The Secret To Effective Centipede & Millipede Control For San Antonio Homeowners

January 22, 2021


Centipedes and Millipedes are not insects. They are more closely related to lobsters and shrimp than to insects and don’t spread diseases to plants, animals, or humans. Centipedes and Millipedes are more of a nuisance than anything else; while they’re considered beneficial because they eat insects, most people don’t want them in their homes.

Identifying Centipedes and Millipedes in San Antonio, Texas

Centipedes and millipedes are superficially similar, but if you look closely, you will see many differences between them.

Centipedes:

  • Have slightly flattened and segmented bodies
  • Are usually brown, but can be grey, red, or greenish-blue
  • Have one pair of legs per body segment
  • The first set of legs has claws
  • Injects venom with their bites
  • Are generally smaller than five inches
  • One species (Scolopendra heros) can reach over nine inches as an adult

Millipedes:

  • Have small cylindrical bodies with many segments
  • Have two pairs of legs per body segment
  • Are usually brown, but can also be red, yellow, or orange
  • Curl into a spiral when threatened
  • Produces an irritating fluid when handled

Never handle millipedes because the liquid they produce to defend themselves causes chemical burns. If all else fails and you do need to handle a millipede, wash your hands with soap until every bit of the liquid they produce is off your hands.

Centipedes can pinch your skin and inject venom when handled. This venom is generally not dangerous to people and comparable to bee stings in irritation, but if you are allergic to bees, wasps, or other insects, you could be allergic to centipede venom.

Life Cycle of Centipedes and Millipedes

Centipedes and millipedes have relatively long lifespans compared to other bugs; the former can live up to six years, and the latter can live up to ten. Centipedes prefer moist, protected areas to live such as under logs, stone, bark, and leaves. This is where they lay their eggs and cover them with a sticky substance. The few centipedes that give birth to live young do so here, too, and usually do so during warmer months.

The house centipede (Scutigera Coleoptera) lives in moist, dark places in your house, and is about 1 ½ inches long. This is the only species of centipede that can reproduce in your house.

Millipedes typically don’t reproduce until they are about two to five years old. They live in compost, leaves, and mulch, and lay their eggs through springtime, eggs which take several weeks to hatch. Millipedes are scavengers, eating decaying matter such as leaves and mulch, and a few species eat insects.

Why are Centipedes and Millipedes in My House?

Most centipedes and millipedes live out their lives outside, with the house centipede being the only exception to the rule. When your house is invaded, it is generally because the centipedes and millipedes are fleeing heavy rains or looking for moisture in a drought. Millipedes can migrate inside in large numbers after heavy rains or when the weather starts to cool. 

How Do I Get Rid of Centipedes and Millipedes?

There are two steps to getting rid of centipedes and millipedes. The first step is to spray an insecticide around baseboards, pipes, windows, and doors. Be sure the pesticide you choose has centipedes and millipedes listed as something the pesticide kills and follow the label directions carefully; the last thing you want is to accidentally poison you and your loved ones.
 
The second step is turning your house into a no-go area for centipedes and millipedes.  Spread a band of gravel from your foundation to any flower beds near the house to make it difficult for the pests to get inside. Move firewood and any other items away from the foundation, seal all access points, make sure the window screens have no gaps or holes in them, and check the weatherstripping under your doors too. Spray pesticides around the base of the house outside to kill these pests before they attempt to come in.
