|Color||House centipedes are dark yellow in color with a trio of dark, longitudinal stripes on the body. Their legs are patterned with alternating dark and light stripes.|
|Size||They range from 1-1.5″ in length. Including the length of their antennae and hind legs, centipedes may appear as long as 3-4″.|
|Appearance||In general, centipedes are easily identified by their long, flat bodies and numerous legs. The black lines that run down the back of the house centipede also serve as a distinguishing characteristic. Additionally, the last pair of hind legs on an adult female is approximate twice the length of the body. Though their name implies that they have 100 legs, centipedes actually only possess a pair of legs per body segment for an approximate total of 30.|
In their lifetime, female house centipedes lay a maximum of 150 eggs in damp soil during the spring and summer and care for the eggs until they hatch. Centipedes pass through an egg, larval and nymph stage before reaching adulthood. Immature centipedes undergo 10 instars that cause their bodies to grow to accommodate additional pairs of legs. Adult centipedes live for approximately one year and overwinter in warm, moist places.
Despite the ecological benefits centipedes provide by preying on insects and other pests, they often cause psychological distress for the occupants of the homes they invade due to their disturbing appearance and darting motions. For this reason, pest control professionals regard the arthropod as a nuisance pest and will take action to remove the creature from homes, if necessary.
Signs of Infestation
May notice adult centipedes in gardens, around house plants or near other sources of vegetation.
Often found in basements and other dark areas.
Look for centipedes around sources of moisture, such as leaky pipes, drains, and bathrooms.
Centipedes are solitary creatures that rarely invade homes in large numbers unless the structure is already infested with other pests that the arthropods typically prey upon.
Prevention & Control
Since centipedes are secondary pests that enter structures to pursue sources of food, prevention should center on making homes and buildings less favorable to prey like carpet beetles, flies, cockroaches, and similar insects.
- Traps: Sticky traps can help determine which pests are attracting the centipedes.
- Habitats: Any sites that make ideal centipede habitats (mainly moisture) should be modified or eliminated.
- Exclusion: Caulk cracks in concrete slabs and block walls. Seal the covers to sump pumps.
- Moisture: Reduce humidity levels by grading the soil around the building to facilitate water movement. The use of dehumidifiers may prove helpful.
A Batzner Service Specialist provides treatment to the perimeter of the building foundation, paying special attention to cracks and crevices in a concrete slab or block walls, sump pumps, and floor drains. The treatment is outside and inside the building depending on the situation. The service specialist also makes sanitation recommendations to help prevent future infestations.
While centipedes in yards or gardens should be left alone, the ones that move indoors may require the attention of a pest professional. They can be controlled by eliminating their harborage areas or removed with a vacuum.
