MILLIPEDE CONTROL
Millipede invasions have long been a problem for many homeowners. Although these invasions seem more likely to occur in the spring and after heavy rains, they have been reported in every month of the calendar year. Thousands of migratory millipedes can create a mess. Once they die, expect a smell that can last for several weeks.
MILLIPEDE BIOLOGY
There are over 1000 species of millipedes in the United States. They are slow crawling, appear to have hundreds of legs and generally gray to light brown in color. Most species take 1-2 years to reach reproductive maturity and can live 5-10 years. They love to live in decomposing thatch, leaves and mulch. They will get nutrition from these locations and may choose a root system of a nearby plant on which to feed. When they breed, the eggs hatch larva which will feed right where they emerge. This leads to large populations or nests which can number in the hundreds. They will remain feeding as long as there is a food supply to support the nest. This could be for a year or two but at some point expect a migration.
MILLIPEDE MIGRATION
Excessive rain, drought or lack of food will cause them to migrate. This phenomenon can occur at any time of the year and may result in several thousand moving in a direction that is in line with your home. The author has dealt with several infestations of millipedes that have numbered in the hundreds of thousands. One customer had so many he used a gas powered blower to round up all the dead ones and 14 Hefty bags to haul them away! This happened over a three day period, but if he didn’t have the right materials or know how to use them, he would have had a mess in his home. Other infestations have lead to thousands stacking up or climbing the side of a house. The migrating millipedes will reach a certain height and simply stop. It is unsure why they do this but it will lead to huge numbers accumulating and a nasty smell when they die.
MILLIPEDE CONTROL
Controlling millipedes involves a series of steps. The first is identifying nest sights. This will allow you to minimize the conditions these pests need which will lead to less getting inside. Look to see where they are invading. In most cases, you will find them along one side or wall of your home. Look around this side of the property. Inspect nearby mulch, compost piles, wood piles, large rocks, pinestraw, sheds, cracks in cement walkways or driveways and stoops. Any of these locations can breed, feed and shelter these pests. If you know where they are coming from, you will be able to treat the area precisely and even remove excessive organic matter available for them. Clean up leaves. Replace old straw that is decomposed. Move log piles away from the home. Seal cracks in cement which allow water to gather. Rake thatch buildup from your lawn. By reducing these conditions, you take away food and harborage these pests need for survival.
MILLIPEDE CONTROL SEALANT
Lastly, if you have a lot of access points through the siding of the home, you should consider a “seal” job. Most homes that get invaded have lots and lots of small cracks, crevices and gaps through which millipedes enter. These entry points should be reduced and/or eliminated with the use of some FOAM SEALENT. These cans are self charged and good for small jobs.
If you have a lot of work to do, it would be wise to invest in one of the professional FOAM GUNS and maybe even the 24″ FOAM GUN. These tools will enable you to apply the sealent quickly and precisely without much waste or missed applications. In other words, they will more then pay for themselves. You’ll need the FOAM CANNISTERS for these guns, which easily fit on either applicator, and cover a much larger area then the smaller cans.
If your home is prone to animal invasions, consider the FOAM WITH REPELLENT. This cannister comes with expanding foam but includes a strong repellent which insects and animals do not like. It may be just what you need to make sure ladybugs and other undesirable home invaders aren’t able to find their way inside quite as easily as they have in the past. Be sure to keep your guns clean by using some FOAM GUN CLEANER. This will help keep the gun functioning and ready to go to work when next needed.
MILLIPEDE CONTROL SPRAY
Once you have done step one, you can treat the problem. Step two is deciding which method of control you need to employ to stop the invasion. Millipedes are not insects. Although many insecticides have millipedes on their labels, most don’t work well for controlling a migration. If you want to stop them quickly and keep them from getting into your home, use a product called BIFENTHRIN. It works well because the liquid form is a micro encapsulate. This means it is essentially a bunch of small capsules which will open up over time exposing the active ingredient. Because these “capsules” are too big to sink down into porous surfaces, they’re able to provide longer residual compared to normal or more traditional liquid concentrates. The end result is that you’ll have more of the active ingredient up high on top of the ground where millipedes are active.
Although you can use it inside, treating outside will keep them from coming in. Spray around the home using one of the SPRAYERS we offer. Be sure to treat on the foundation spraying a deliberate swath at least three feet up from the ground. Go as high as you have them crawling on the home to kill what is there and stop new ones from re infesting. It is most common that one or two sides of the house will have the most activity. Be sure to concentrate your efforts where the activity is. Since both pests like to live adjacent to the foundation, it is recommended that you treat the ground around the home as well. Pay attention to the plants, shrubs and root systems of plants. Spray around the trunks and the ground of any plant you think may have a nest. Watering after you spray will help the product to sink down and work it’s way deep to where nests may be feeding.
MILLIPEDE CONTROL GRANULES
If you simply have too much mulch or turf area to treat with liquid, use BIFEN GRANULES. This product is a granule material which works by killing as well as repelling these pests. Broadcast the granules into mulch or turf that you think is infested. The GRANULE SPREADER applicator is easy to use and will let you get even and uniform coverage when making the application. The granules are weather resistant and will last longer than the spray. The granules won’t work as quickly as the spray, but they will enable you to treat large areas economically and effectively.
MILLIPEDE CONTROL AEROSOL
If you have a lot of activity in the home, you may use the Bifenthrin inside. If you believe the nests may are behind walls or in hard to treat cracks, DFORCE AEROSOL is designed to let you treat these areas. It uses Deltamethrin as the active ingredient and with it’s special tube injector, you will be able to get into tight cracks and joints these pests like to hide. Use the Dforce aerosol for neat and penetrating applications.
Step three is the ongoing maintenance of watching and making sure to minimize nest locations. By stopping the nests from being able to develop, you are stopping the invasions which would undoubtedly follow. In most cases, homes which experience migrations are more likely to have it happen again. In fact, most people believe the migration to be a “freakish” occurrence that doesn’t need to be attended to. The fact of the matter is that millipedes take a long time to develop. This period of development may be several years before enough have matured to migrate. Once they begin to move and relocate or die, the cycle is forced to start again. Don’t expect to see any for a year or more. However, next time could be a lot worse if left untreated.
Millipedes are not insects but are most definitely considered pests. They like to live in the same area but do not eat the same food. If left untreated, populations can build up and lead to mass migrations. These migrations can infest your home with messy, smelly dead bodies that seem to get everywhere. To stop them from coming inside, treat with Bifenthrin. If you have large turf or mulch areas where you think they may be living, treat with Bifen Granules for better coverage. If you have them in the walls, Dforce Aerosol is easy to use and will reach deep into the voids they like to live.

We have been living at a property on one of the Finger Lakes in New York State for three + years. Each year the millipede migration seems to get worse. The small blackish/brown milipedes cover one side of our two story house at times. They seem to have a route across our livingroom rug and they we find them in various other places in the house too but not to the same extent as in the living room. I am forever vacuming them up around three weeks of the beginning of the Summer or so. It is very freakish, but once the invasion stops I forget all about them and can go back to enjoying our Summer on a beautiful lake. My problem is the odor. I saw a show on t.v. that said the order is Hydrogen Cyanide. I have discovered that during the invasion period I get headaches and feel ill. I am worried about our health now and also worried about using chemicals in the house. Please advise about any health issues from the millipede odor or pesticides. I want to tackle this problem this year before the invastion starts. I’m afraid with our weird and mild Winter here this year that the invastion could start sooner than most years.

@P.T.: First and foremost, odors can have a wide range of impact on people. Decaying odor, like that released from dead or migrating millipedes, has been reported as making people feel ill. But it’s not lasting or unhealthy and though annoying and in come cases nauseating, it will pass.
As for odors from pesticides; these can be more hazardous if someone is exposed to certain products for extended periods of time. This can happen when treating with aerosols inside the home. This is also why we recommend most treatments for millipedes to be done outside and in fact, very little if anything should be applied inside even if you’re seeing some like you describe. Stick with the “vacuum only” approach inside and spraying outside which in the end will work fine.
By using this approach you’ll both minimize and even eliminate exposure to the people living in the home and in fact you’ll even solve the problem faster. The main reason for using this approach is to address the millipedes where they are living. As explained in our article above, millipedes thrive under grass clippings (make sure you’re removing and recycling grass clippings! This is a major contributor of millipede problems), lawn thatch, pine straw and other mulch. And if you leave the millipedes to live as they please, they will populate to extreme numbers eventually migrating all over the property. And it’s this migration that leads to them getting inside homes. Based on the millipede live cycle, it only makes sense to get them where they’re nesting and this means mostly if not only outside treatments are needed.
So for now, I suggest applying Complete Insect Killer Granules to the lawn and mulch areas of your property ASAP. Millipedes will feed year long and though they tend to slow in the winter, mild temps mean they’ll be more active which in turn leads to bigger numbers and larger migrations come the spring following a mild winter. I have family in upstate NY and they are reporting a mild winter which leads me to believe the millipede migrations this year will be big.
After applying the granules, spray over the top with Cyonara RTS. This will provide the quick kill needed to knock down existing millipedes. The granules will provide 1-2 months of protection so if you treat now, you’ll want to do another application around the end of March and then again in the beginning of May. Treating for millipedes during the first six months of the year can really cut down on how many you see so the time to strike is now. With any luck, you won’t see them the second half of the year if you do a good job now.
FYI, I’m listing different granules and liquid from our article because the Bifen isn’t registered for sale into your state but the Complete and Cyonara will work just as well. And they’re odorless so they’re better suited for use around your home. Here are links for these two:
