Millipede control in Orange County, NY

Millipede Exterminators for Orange County Basements, Garages and Slabs

One millipede is a curiosity. Two hundred of them dead on the basement floor every morning in October is a problem with a cause, and it is almost always outside. Call to reach a local pro who treats the source, not just the floor.

Why they all show up at once

Millipedes live in the leaf litter, mulch and damp soil around your house, eating decaying plant material. Most of the year you never see them. Then a stretch of heavy rain floods their habitat, or a dry spell sends them hunting for moisture, or the first cold nights of fall push them to move, and they march. Mass migrations, sometimes huge ones, are a known millipede behavior, and your foundation just happens to be in the way.

Indoors they don't last. Millipedes need damp conditions and usually dry out and die within a few days in a heated, dehumidified room. That is why many homeowners find more dead ones than live ones. The real fix is reducing the population and the moisture right against the house, and closing the gaps they crawl through.

Millipede or something else?

Three long, many-legged critters turn up in Orange County basements. Telling them apart changes the plan.

MillipedeHouse centipedeWireworm
LegsTwo pairs on most body segments, short and wave-likeFifteen pairs, very long, sticking out all aroundThree pairs near the head only
BodyRounded or slightly flattened, brown to black, often 1 to 1.5 inchesYellowish gray with dark stripes, long antennaeHard, shiny, tan or copper, worm-like
MovementSlow and steady, curls into a coil when touchedVery fast, darts awaySlow, mostly found in soil
What it eatsDecaying leaves, mulch, rotting woodOther insects and spidersRoots and seeds in gardens
Bites?No. Some release a smelly fluid that can stainRarely, and only if handledNo

If yours is fast and leggy, see our house centipede page instead. Centipedes hunt the very bugs that live in damp basements, so the two often show up together.

Sweeping up millipedes every morning?

A perimeter treatment during the migration usually cuts the numbers fast. Local pros can often get out within a day or two in the fall rush.

When millipedes move around here

  1. April – May

    Activity picks up as soil warms. Small numbers wander into garages and walkout basements after spring rains.

  2. June – August

    Heavy summer thunderstorms can trigger sudden movements, especially on lots with deep mulch beds or poor drainage.

  3. September – October

    The main event. Cool nights and fall rain send the biggest waves toward foundations. This is when most calls come in.

  4. November – March

    Millipedes go quiet in the soil. A few may still turn up in finished basements built partly below grade.

What makes some Orange County houses millipede magnets

The houses that get hammered share three things: organic material piled against the foundation, soil that stays wet, and an easy way in. Orange County has plenty of all three.

Newer subdivisions in Monroe, Chester and the Town of Wallkill are landscaped with thick mulch beds right up to the siding, often on top of heavy clay fill that drains slowly. The millipedes breed in that mulch all summer. When they move in fall, the sill plate of a slab-on-grade house or the gap under the garage door is inches away. You will see the same thing across Goshen, Chester and Blooming Grove.

Older homes have their own problems. Fieldstone and block foundations in villages like Walden and Goshen have mortar joints that have crumbled enough to let small arthropods through, and basements that are damp most of the year. Houses along the Wallkill River, the Moodna and the low ground in the Black Dirt region see high water tables that keep the soil soaked well into fall.

Wooded lots add another layer. Homes backing onto forest around Tuxedo and the Upper Delaware collect deep leaf litter every year, and leaves left along the foundation over winter turn into prime millipede habitat by summer.

Changes that cut down the next wave

Treatment knocks numbers down, but these are what keep the problem from coming back every fall.

  • Pull mulch back so there is a 12 to 18 inch strip of bare ground or stone along the foundation
  • Rake leaves away from the house in fall, and don't store leaf piles or compost against the wall
  • Clean out window wells and add covers
  • Extend downspouts several feet away from the foundation
  • Regrade low spots where water pools against the house
  • Replace worn door sweeps and garage door bottom seals
  • Seal sill plate gaps and slab cracks with caulk or foam
  • Run a dehumidifier in the basement, aiming for roughly 50 percent humidity
  • Move firewood, stone piles and landscape timbers away from the house
  • Trim shrubs so sun and air reach the soil along the foundation

What a professional millipede treatment involves

Find the source

The technician walks the outside of the house looking for the habitat: mulch depth, leaf buildup, wet soil, and where water from the gutters is going. Inside, they look at where millipedes are concentrated to pin down the entry points.

Treat the perimeter

A residual insecticide is applied as a band around the foundation, usually several feet out on the soil and mulch and a short way up the wall. Granular products may be used in heavy mulch beds. This is the step that stops a migration in its tracks.

Handle the inside

Live and dead millipedes are vacuumed up, and cracks and gaps at the slab edge or sill may get a targeted crack-and-crevice treatment. Spraying the whole basement floor isn't needed and doesn't help much.

Seal and advise

Many pros will seal the obvious gaps on the spot and give you a short list of drainage and landscaping fixes. If the house also has crickets, earwigs or spiders, the same perimeter work usually covers them.

What affects the cost

Size of the perimeter
A big house with a long foundation and wraparound beds takes more product and time than a ranch.
Landscaping
Deep mulch, stone walls and dense plantings along the house all need treating.
One visit or a plan
A single fall treatment works for many homes. Bad sites do better on a seasonal perimeter plan that also covers ants and spiders.
Sealing work
Replacing door sweeps or sealing a long sill plate adds labor but saves repeat visits.
Other pests
Bundling millipedes with centipedes, crickets or ants is often cheaper than separate calls.

Millipede FAQs

Are millipedes dangerous to kids or pets?

No. They don't bite or sting. Some species release a defensive fluid with a strong odor that can irritate skin or stain surfaces, so wash your hands if you pick one up, and don't let a dog chew on a pile of them.

Will they damage my house?

They don't eat wood framing, wiring or food. The damage is mostly the mess and the smell of dead ones. Their presence does tell you there is excess moisture around the foundation, which is worth fixing on its own.

Why did they show up after we redid the landscaping?

Fresh, deep mulch is ideal millipede habitat. Beds installed one spring often produce a big migration that fall. Thinning the mulch near the house and leaving a stone or gravel strip helps a lot.

Do I need treatment every year?

Not always. If you fix drainage and pull back the mulch, a single treatment may be enough. Houses on wet lots or next to woods often benefit from a fall perimeter treatment each year.

Need a millipede exterminator near me?

Typing "millipede exterminator near me" into your phone with a dustpan in your other hand is a very Orange County fall experience. The good news is that this is quick, routine work for local pest control companies, and most of them can fit a perimeter treatment in quickly once the migrations start.

Call us from Warwick, Middletown, Newburgh or anywhere in between. We will connect you with an independent pro who works your part of the county and can also look at the centipedes or ants that tend to come with a damp foundation.

Doing it yourself first?

A shop vac and a broom handle the ones already inside. Store-bought granules spread along the foundation can help on a small house, but read the label and keep kids and pets off treated areas. If you are still finding dozens a day after a week, or the house sits on a wet lot, the source is bigger than a bag of granules will reach.
