Everyone thinks of roaches as tiny creatures which invade dirty homes and apartments. In fact, there are many species of roaches in North America and most of them live outside. If given the chance, these “other roaches” will readily move into any home. Like most roaches, these creatures are active at night, crawl in kitchens and bathrooms, and is too fast to catch.
In case this is not the roach informatioin you were looking for, we have other in depth articles here: AMERICAN ROACHES GERMAN ROACHES WATERBUG ROACHES
LARGE ROACH INFESTATIONS
Large roaches are common in North America. One of the most common is the American Roach. These large roaches generally exist outside. They live in wood piles, pine straw or wood chips. They may live in trees, bushes or plants. And since they exist alongside our apartment buildings and homes, they will forage inside for food and shelter. Once foraging inside, it is not unusual for them to start nesting in crawl spaces, attics or cabinets. And even though they do not breed as fast as German Cockroaches, they will infest a home or apartment over time.
If you are seeing Large Roaches in the kitchen area, the void between the kitchen cabinet bottom and the floor is a common nest site. Many times they will crawl into the holes around a pipe which is coming through a wall. Other times they may nest in ovens, refrigerators or dish washers. If you are experiencing a problem in upper level units, Large Roaches may be nesting in the attic. They love to take advantage of moisture which will build up around clogged gutters. When these gutters are cleaned, the Large Roaches will move into the attic. And since they travel further than a German Cockroach, it is not unusual for one nest to have foraging roaches getting into numerous units. If your house has a crawl space, you will find nests around points of entry. Typical points of entry include water pipes under the kitchen and bathroom, cable lines, or gas lines. All entry points from a crawl space must be treated to prevent infestations.
LARGE ROACH CONTROL
There are two ways to deal with these Large Roaches. The first is preventive maintenance and we believe this is the best way. Make sure your gutters do not become clogged. They should be cleaned when needed and inspected to make sure they are doing their job. If any roof shingles need to be replaced, do not wait until major water damage occurs. When roof shingles are damaged, replace immediately. Water leaks may be small and hard to identify but insects quickly take advantage of such moisture. And when the leak is repaired, the bugs will persist. We know air conditioning leads to many pest problems. Moisture will accumulate around the units and pests will nest here. Make sure air conditioning units are draining away from the structure. Air conditioners are turned off in the fall and when you turn them off, you dry up the water supply for many pests. Once this supply of water dries up, these pests will forage inside.
If there is no water for them around the air conditioning units, you do not have to worry about these pests moving inside come the fall. Most people love a pretty garden. Pine straw and wood chips around the foundation are common. Such mulch provides year round nest sites. Whatever material you use will be breaking down and this breakdown creates heat and food. Large Roaches love this nest site and will live comfortably even when outside temperatures are freezing. If you have such sites, try to keep them dry. If you must water, periodic treatments of such sites will reduce the nesting and reproduction of Large Roaches. Other preventive measures include sealing windows, pipes, cables and siding with caulking. Vents to crawl spaces must be functional. Damaged siding should be repaired. Cracks in concrete walkways should be filled. Large Roaches are opportunistic. They will take advantage of any site which provides moisture and protection.
LARGE ROACH OUTSIDE BAIT
The second way of dealing with these Large Roaches is to treat their nest sites. Instead of waiting till they move inside, treat outside areas such as mulch beds. We recommend MAXFORCE GRANULES in these mulch areas. The granules will sink down to where it counts. Maxforce is labeled for ants and crickets, but Large Roaches find them very attractive. They are attracted to it and once they feed they will die.
Maxforce Granules: http://www.bugspraycart.com/bait/granule/maxforce-gran
LARGE ROACH CONTROL SPRAY
In addition to the Maxforce Granules, you should be spraying the foundation, window frames, door frames, decks, patios, and any route of entry with a liquid residual. ORTHENE WP is a great product as is DEFENSE SC. By treating the outside perimeter of your home, you will create a barrier the Large Roaches cannot get through. Use one of our SPRAYERS for applying the material. This treatment will work for other invaders as well, but really helps in controlling these large Large Roaches. If you feed your pet outside or have bird feeders, chances are some of these outdoor roaches are feeding as well. Over time, their population will swell. If left to nest on the side of your home around decks and windows, it is only a matter of time before they get inside. Start perimeter pest control to keep them out.

Solo 454 Sprayer: http://www.bugspraycart.com/equipment/sprayers/solo-1-gallon-sprayer
If the attic is infested, it’s best to use a dry formulation called “dust”. This treatment is very effective and lasts a long time. Spraying a liquid in the attic is almost useless because it is so dry and porous. Dusting lasts long and works a lot better. Large Large Roaches will move into attics if given the chance. Many attics which have roach problems had conditions outside the home which were conducive to having an infestation. The most common attractant is having your gutters clogged. The moisture which builds up supplies much needed water. Once established in the soffits and facia boards, they will move inside.
LARGE ROACH CONTROL DUST
If your attic is dry, use the DRIONE. If you live in a humid area or have high levels of moisture in your attic, you will get better results using the DELTAMETHRIN DUST. Apply either of these products with a DUSTIN MIZER. It is easy to use and will distribute the dust ten to twenty feet. If the infestation has gotten into your crawl space, use the Deltamethrin Dust. It is formulated to handle the higher levels of moisture you would expect to encounter in a crawl. Either of these dusts can be used inside and can be applied with a HAND DUSTER but you will get better results using either of the following baits.

Dustin Mizer: http://www.bugspraycart.com/equipment/dusters/dustin-mizerdeflector
Hand Duster: http://www.bugspraycart.com/equipment/dusters/crusader
If the infestation has made it to the living areas of the home, use a bait for quick and complete control. In general, these insects have come inside seeking food and water. The bait formulations we use today have high levels of moisture built in and have food additives Large Roaches cannot resist. Baiting requires less preparation and presents little if no hazard in the home to pets and children. The biggest advantage of using a bait for Large Roaches is that it takes the guess work out of getting control.
LARGE ROACH CONTROL – THE OLD WAY
The old time approach to Large Roach control involved spraying everywhere. We treated all surfaces with the hope that nesting Large Roaches would walk over the residual pesticide. The end result is that you spray a lot and the roaches learn to avoid treated surfaces. If you are not able to deliver the product where the roaches are living and nesting, they will continue to prosper. This is no longer a problem when using the baits. Simply make placements where you are seeing activity. Keep these placements clean, dry and discreet. Make them about two feet apart.
LARGE ROACH CONTROL BAIT – INSIDE BAITING
Large Roaches like to feed where they are nesting and you will be able to see their droppings when populations build up. Although there are many baits being produced, MAXFORCE GEL and ADVION are the two Large Roaches seem to like. These products will lure roaches and once they feed, they will die. If left undisturbed, these products will remain active for up to three months.

LARGE ROACH TRAPS
There are a few other tools which may help in your battle with these large Large Roaches. First, the installation of ROACH TRAPS can help by both catching any foraging as well serving as an early detection monitor. They are easy to use, can be set out anywhere without posing any type of hazard and are easy to maintain. It’s a good idea to have them installed where you either know or think there may be some Large Roach activity; check them daily to see if your concerns were warranted. If you find any trapped, step up your control effort by installing some bait or doing some treatments.
Roach Traps: http://www.bugspraycart.com/traps/pheromone-and-food/roach-trap-6-pack
LARGE ROACH HAND HELD ZAPPERS
For the occasional pest that is seen during the summer months or after long periods of rain, get either the HAND HELD ZAPPER or our BUG VACUUM/ZAPPER. These tools are handy, easy to use and excellent to have around for most any pest. The Hand Held Zapper is better suited for flying insects though when placed over any large Large Roach and turned on, it will “fry” them in a few seconds. The Bug Vacuum is ideal because it allows you to both “trap” and “remove” crawling insects easily whether you are trying to do this on the floor, wall or ceiling. None of these tools are likely to control any type of infestation but all will help and are certainly adequate for the “occasional”s unwanted “intruder”.

Most Large Roach infestations are easier to control than German roaches. They take more time to develop and do so in smaller numbers. However, they are still roaches and most people will not tolerate sharing their living space with them. Preventive maintenance will stop them getting in; treating key nest sites will knock out existing populations.

michelle @ 4:57 am
we live in oakland fl. no matter how clean we keep the house what or how much bait, dust or spray we use the roaches are horrible. at any point in time day or night thousands of roaches are on the ceiling, floors, walls, counters, cupboards, oven and fridge. my fiances mom is in icu for pnuemonia and our dogs are getting eaten alive. please help us.
Tech Support @ 7:11 am
For now, read through our Roach Control article which goes over all the products you’d need. Based on what you’re describing, I would say to stop spraying and dusting and instead use nothing but the Roach Gel mentioned above. When problems get bad like you describe, using at least two flavors is suggested so get the following:
Roach Gel: http://www.bugspraycart.com/bait/gel/maxforce-magnum-roach-gel-1-oz
Advion Roach Gel: http://www.bugspraycart.com/bait/gel/advion-roach-gel
I also suggest getting our Bait Gun for dispensing the gel because it will enable you to apply it easier and more accurately.
Bait Gun: http://www.bugspraycart.com/equipment/bait-applicator/blue-bait-gun
Get a box of each (4 tubes of each) along with a bait gun and start placing small dabs every 2 feet where you see them. Use 1 tube of each flavor every 2 weeks. This means you’ll have enough bait to last 8 weeks. If you follow this routine, by the end of the 8 weeks most if not all of the roaches will be gone. Give us a call toll free at 1-800-877-7290 if you need further assistance.

We are having more of an issue with seeing “baby” American roaches in our downstairs room (used to be a garage). We only see about 2-3 per week but I want to do something before it gets worse. Does this sound like an “infestation” problem with roaches in the walls…since we see more babies than big roaches? We have been pretty good with sprays and baits so I wonder if this is a sign that these are old eggs hatching.
Tech Support @ 8:25 am
Unlike small German Cockroaches, large roaches like American, Oriental and Wood roaches tend to originate from outside. For this reason, the focus of your attention should be outside and you should use the strongest products available for this if you want to get the best results. That’s because outside treatments don’t last long and most any common, over the counter product won’t be designed for this kind of job.
So in this case, my first concern is what you’re using. Make sure inside it’s nothing but the Roach Gel listed above along with some Roach Traps and spray’s we recommend. Also, do not spray inside as this can interfere with any bait applied making it useless. More importantly, the gel we recommend is one of the only gels we’ve seen work well on large roaches so it’s important you use this exact brand.
Roach Gel: http://www.bugspraycart.com/bait/gel/maxforce-magnum-roach-gel-1-oz
Roach Traps: http://www.bugspraycart.com/traps/pheromone-and-food/roach-trap-6-pack
Now since these roaches come in from the outside, there is usually 1-2 areas of any home which tend to be more vulnerable compared to others. My guess is the room you reported seeing them in – because it used to be a garage – has something different about it either on it’s outside shell or inner wall structure that makes it more likely to harbor a roach population. So for starters, we need to sure up this part of your structure with some Drione Dust.
Drione: http://www.bugspraycart.com/insecticide/dust/drione-dust
Drione should be applied to as many “ports” in the room as possible. A port would be a route of entry and includes areas like electric wall outlets, under electric switch plate covers, in light fixtures where they attach to the wall or ceiling, under any “fixed in place” counter or cabinet as well as any hole where electric lines or water pipes pass. Apply the dust with a Hand Duster and do this throughout as much of the home as you can because once you treat these areas with Drione, all pests will avoid the area making this kind of treatment a great way to “exclude” insects from any home.
Hand Duster: http://www.bugspraycart.com/equipment/dusters/crusader
Lastly, don’t forget the outside of the home. This is where most people fail when it comes to large roach control. In fact, I bet this is the area you really need to target around your home and for this I recommend two main treatments.
First, apply a band of Bifen Granules around the home coming out at least 10 feet and applied to every turf section around the perimeter including grass, pine straw, flower beds, etc. Roaches thrive in these areas and from there commonly migrate inside when it gets too hot, dry, moist or cold outside. Keep this are insect free and chances are good your home will be insect free inside.
Bifen Granules: http://www.bugspraycart.com/insecticide/granule/bifenthrin-g-25-lb
Next, spray the foundation thoroughly coming 3-5 feet up the siding with Cypermethrin or Deltamethrin. These residual products will keep insect pests off the home and should be applied around windows, door frames, gutters and even the roof line where it meets any gutters you have installed. This area, around rain gutters, is especially important when it comes to roaches they tend to thrive in such areas if left untreated. Clogged gutters are really a roach magnet but even clean ones tend to attract all kinds of pests including wasps, ants, bees, roaches and scorpions. From there any of these can get into your attic and/or wall void which in turn leads to inside activity.

We have seen three giant roaches at night in the past 2 months. Always in the same place – running from under the bed in the bedroom – which has no food in it ever, no drains, no connected bathroom, and is on the 15th floor of a prewar building.
Is it possible that there is a nest under the bed or in the wall behind the bed?
Tech Support @ 11:55 pm
If there is someone sleeping in the bed, they are most likely the “food” you think isn’t present. Let me explain…
Large roaches like Oriental, American and others will routinely feed on peoples hair and dead skin. I’ve seen them come out at night and feed upon people as they sleep. As horrible as this might sound, they don’t eat a lot and in most cases, target hair, fingernails and shed skin. For this reason it’s easy to miss them and not even know they’re around.
Now if you’re seeing them around the bed, my guess is they’re living close by. Regardless of where they’re living, large roaches are easy to control so if you want them gone, here’s what you do.
Just set out some of the Roach Traps we have listed above along with some of the Roach Gel. Apply both around the room where you see activity but focus on the bed area. After making the application, make sure no one is sleeping in the bed for a week. This way the roaches will surely find the gel and within 1-2 nights any active in the room will feed and then die in a few days. In most cases, the problem will be resolved in 7-10 days.

I recently had my house in Los Angeles painted and gutters replaced. Shortly thereafter, over the course of two nights, I found two huge beatles. First one on the kitchen floor and then one on the carpet in the adjacent bedroom. When found, they were already dead. I’ve laid no poisons or baits, but want to ensure myself that no long term problem exists. Can you offer a suggestion in how to proceed, on what may have started this issue, and what might be killing them?
Tech Support @ 7:58 am
Many exterior paints contain solvents which are plenty toxic enough to kill insects. And because these solvents are highly volatile, they’ll affect any insect living close to the newly painted surface. So in this case, I wouldn’t be surprised if fumes from the paint affect them which in turn caused them to migrate and die.
I’ve also seen the act of washing with bleach or detergent have a similar impact so if the exterior of your home was power washed or prepped in some manner prior to getting painted, this could lead to insects migrating out and dying as well. And during the course of this migration, some could have ended up inside the home (which you found).
In the end, trying to learn if it was the paint, a cleaner, a paint remover or just old age that killed these bugs would be near to impossible. But one thing is for sure, you’ve got them living on your home and if you don’t do some of the treatments recommended above, more will show up inside and eventually, you’ll get some nesting inside too.
To prevent this from happening, you’ll need to employ some of the products listed above. I suggest you start by dusting your attic space with Drione Dust. You see, gutters attach to homes along facia boards and these boards adjoin the home where the roofing meets soffits. This area is a “weak” area for many homes as a lot of cracks, seams and entry ways exist along this line (where the gutters mount) and large roaches love this area. They typically nest in the insulation of the attic and then forage out to the gutters to get moisture and food. Dusting the attic and paying extra attention to this area around the perimeter of the attic space can work really help at removing insects that might want to use it as a prime nest site.
Drione: http://www.bugspraycart.com/insecticide/dust/drione-dust
Use a power duster to do the application or a Dustin Mizer.
BG 2300: http://www.bugspraycart.com/equipment/foggers/bg-my-t-lite-2300-120-v
Dustin Mizer: http://www.bugspraycart.com/equipment/dusters/dustin-mizerdeflector
Now Drione can also be used inside to keep roaches and other pests out of the home. It’s highly repellent to insects and once applied to voids like those behind electric outlet covers, electric light switches, light fixtures, etc., roaches won’t be able to use these pathways to enter living spaces. Use a Hand Duster for these applications and treat any room where activity is found. The good news here is once applied, the treatment will last a year so you don’t have to continually apply the material.
Hand Duster: http://www.bugspraycart.com/equipment/dusters/crusader
I also suggest you do a good treatment to the exterior of the home with the Suspend listed above. This long lasting active should be sprayed up to the roof focusing on the soffits and gutters. If you treat the entire perimeter of your home every 1-2 months, you should be able to remove this location as a nesting location for any insect which in turn will keep them out of the home.
Suspend SC: http://www.bugspraycart.com/insecticide/liquid/suspend-sc
Eliminator: http://www.bugspraycart.com/equipment/sprayers/eliminator-gallon-sprayer
Lastly, set out some Roach Traps inside the home. This way if any do come inside, you’ll have in place a trap to collect them. Now if you start catching 1 or more roaches a month, you should then either spray your baseboards with Suspend or set out some Roach Gel where you’re finding the activity. Either will take care of the problem equally and really, it’s just a matter of you deciding if you prefer to spray or bait in the living area.

Ariel @ 6:06 pm
Thank you for this very informative article. We have seen several roaches ranging from tiny to alarmingly large in and around our kitchen cabinets. We saw a few medium sized ones when we first moved in, killed every one we saw, then didn’t see any for a few weeks. Then suddenly we saw a HUGE one in the kitchen cabinet (an upper cabinet) and then many tiny ones. We’ve suspected that perhaps they were living under the sink cabinet since there is a huge hole in the cabinet bottom by the pipe. Some of the other kitchen cabinets are also deformed and needing replaced so it could also be one of those. We’ve decided to replace the cabinet bottoms right away to hopefully help fix this bug problem!
My question now is, when we go to fix the cabinets and if we find a nest there, how do we keep them all from scurrying away and then migrating to other places in our home?? And what kind of followup should we do after replacing the kitchen cabinet bottoms and destroying the supposed nest?
Tech Support @ 6:57 pm
In general, it’s never a good idea to mess around with an insect or animals nest for the exact reason you’re concerned; there is a high likelihood during the work some will up and relocate. This is especially true with bees, wasps, ants and roaches.
And though there is a chance you’ll be fast enough to kill a few when a nest is disturbed, the odds are almost certain that several will relocate and in the process, set up new nests which in turn will be harder to control.
So avoid this scenario, the solution is simple. Get some of the Roach Gel mentioned in our article and place it out in these areas now, before you do any work. Let the gel do it’s thing for at least 2-4 weeks and I would say anytime after 4 weeks you could safely do the cabinet replacement work without any chance of roaches relocating and forming a new nest.
Roach Gel: http://www.bugspraycart.com/bait/gel/maxforce-magnum-roach-gel-1-oz
And once the new cabinets are in place, I’d place out some more gel just be sure they’re gone. Nothing is more nasty than roaches in a kitchen cabinet so don’t give them any chance of relocating and moving throughout your home! Currently you know just where they’re at and this gives you a big advantage. Don’t waste it; take action with the gel now and get rid of them for good.
NK @ 11:32 pm
I’m glad I found your article online. I moved to the US from the UK and roaches have been a rude awakening as I had never seen one until I moved here. Roaches have been a problem in each house we have leased. The first house I hired people to spray which never worked permanently. The second house I took control and used sprays from local stores which worked temporarily but never permanently.
Now we have purchased our new home and the roaches are appearing. One small one every other week and today a huge one on the kitchen cabinet. Obviously out of panic I headed to my local store and stocked up on everything I could find to tackle this problem from the outside to the inside. But I feel these regular products are not the answer. Please can you advise what can I do to get rid of roaches long term? Thank you.
Tech Support @ 8:06 am
The products you’ll need to get rid of these roaches long term are all listed in our article above. Just click on them where they appear in our article if you want to read up more on what they are, how to use them and how to purchase them from us.
Keep in mind, these true are professional grade products, not standard over the counter retail products like big box stores or home centers sell. In fact, we have a Lowes on one side of us and a Home Depot on the other and they send us customers all the time. Why? Because what we carry is what the pest control companies use and if you want to get professional results, you’ll need to treat like they do using the products they’d be using.
To start, you’ll need some Maxforce Granules. Apply 2-4 oz to the ground, mulch, pine straw, flower beds, etc. around the home.
Maxforce Granules: http://www.bugspraycart.com/bait/granule/maxforce-gran
Next, spray the siding of the home right up the gutters, around windows, garage doors, windows, etc. where the roaches might be nesting and/or entering. A good material for this is the Suspend.
Suspend SC: http://www.bugspraycart.com/insecticide/liquid/suspend-sc
Lastly, set out some Maxforce Gel ins the home anywhere the roaches are seen. Make discreet placements where the roaches are thought to be active and once the gel is in place, the roaches won’t be able miss it.
Roach Gel: http://www.bugspraycart.com/bait/gel/maxforce-magnum-roach-gel-1-oz
More details on how to best use these products can be found above in our article.
