After every heavy rain, millipedes crawl through your foundation cracks by the dozens. Our perimeter barrier treatment stops them before they get inside and keeps your basement millipede-free.
Millipedes are dark brown or black, worm-like creatures with many tiny legs — two pairs per body segment. They typically grow 1 to 2 inches long, move slowly, and curl into a tight coil when disturbed. Despite their name (which means "thousand legs"), most species have between 30 and 400 legs.
Millipedes need moisture to survive. They live in damp soil and leaf litter outdoors, and migrate indoors when rain floods their habitat or drought dries it out.
They crawl through foundation cracks, window wells, and gaps around pipes to reach your damp basement. Dozens can appear overnight after a heavy rain.
When threatened or after they die, millipedes curl into a tight spiral. Some species also release a defensive fluid that can stain surfaces and irritate skin.
Watch for these signs in your Michigan home:
Finding live or curled-up dead millipedes on your basement floor, especially near walls, drains, and foundation cracks.
A sudden appearance of many millipedes inside your home following heavy rain — they can go from zero to dozens overnight.
Millipedes crawling up your home's exterior walls, foundation, or gathering in window wells, especially in the evening.
Millipedes appearing in bathrooms, laundry rooms, and other damp areas of your home beyond just the basement.
A noticeable musty or unpleasant smell in your basement during large millipede invasions, from their defensive secretions.
Michigan's wet climate makes it prime territory for millipede problems. Our frequent spring rains, humid summers, and fall storms repeatedly saturate the soil around foundations — driving wave after wave of millipedes toward your home. Ann Arbor, Jackson, and Lansing homeowners with mulch beds, leaf litter, or gardens close to their foundation are especially at risk.
Michigan's older homes with stone or block foundations and basement window wells are particularly vulnerable to millipede invasions. The tiny cracks and gaps that naturally develop in these foundations are perfect entry points. Without professional perimeter treatment, millipede invasions will happen every time it rains heavily.
We don't just sweep up the millipedes already inside — we create a barrier that stops them from ever getting in.
We inspect your foundation, window wells, and perimeter to identify all entry points and moisture conditions that are attracting millipedes to your home.
We apply a professional-grade perimeter barrier around your foundation that kills millipedes on contact before they can enter your home. We also treat interior areas where they are currently active.
We provide specific recommendations for reducing moisture around your foundation — including drainage improvements, mulch management, and sealing entry points — to make your home less attractive to millipedes long-term.
EPA-approved perimeter treatments that are safe for your children and pets once dry.
We understand Michigan's moisture challenges and address the root cause — not just the symptoms.
Same-day and next-day appointments available throughout Ann Arbor, Jackson, and Lansing.

Millipedes live in moist soil outdoors. When heavy rain saturates the soil, they migrate toward buildings seeking shelter. Michigan's frequent rains drive them through foundation cracks, window wells, and gaps around pipes into your damp basement.
Millipedes do not bite, sting, or damage your home's structure. Some species secrete a mild defensive fluid that can stain surfaces and irritate skin. Their main impact is the unpleasant experience of finding dozens of curled-up millipedes in your basement.
Dark brown or black, worm-like creatures with many tiny legs — two pairs per body segment. Michigan species are typically 1 to 2 inches long. They move slowly and curl into a tight spiral when disturbed. Despite the name, most have between 30 and 400 legs.
Most common in spring (April-May) and fall (September-October) following heavy rain. They can also come indoors during dry spells. Mass migrations happen suddenly — zero millipedes one day, dozens the next after a storm.
Reduce moisture around your foundation: keep gutters clear, reduce mulch near the house, fix leaks, and use a dehumidifier. Professional perimeter treatment creates a barrier that kills millipedes before they enter. Sealing foundation cracks also helps.
The next rainstorm will drive another wave of millipedes toward your home. Call now for professional perimeter protection.
