How to Get Rid of Centipedes at Home

October 20, 2026

Why Centipedes Enter Your Home

Centipedes follow moisture, warmth, and food — mainly other insects. If you see them, it usually means smaller pests are already present.

They enter through cracks in walls, gaps under doors, and drains. Basements, bathrooms, and laundry rooms are their favorite spots.

Are Centipedes Dangerous?

Most house centipedes are not deadly to humans. Their bite can cause brief pain and minor swelling, similar to a bee sting.

Still, no one wants them crawling across the floor at 2am. Here is how to deal with them effectively.

Step 1 — Remove Their Food Source

Centipedes eat other insects. Eliminate their prey and they will leave on their own.

Start by treating crawling pests with Sulguy Crawling Pest Control Powder Spray. It is odorless and dissolves easily in water, making it safe for indoor use.

For broader crawling pest control, Sulguy Diatomaceous Earth with Peppermint is a natural powder that damages the exoskeletons of insects without toxic chemicals.

Step 2 — Reduce Moisture

Fix leaking pipes. Run a dehumidifier in your basement. Keep bathroom floors dry after use.

Centipedes cannot survive in dry environments. Moisture control alone can cut their population significantly.

Step 3 — Seal Entry Points

Use caulk to seal gaps around pipes, window frames, and door edges. Check behind appliances for hidden cracks.

Place Sulguy Crawling Insect Glue Traps along baseboards and in corners. These catch centipedes and any other crawling insects moving along walls.

Step 4 — Repel With Peppermint

Centipedes dislike strong scents. Spray Sulguy Peppermint Bug Spray along baseboards, around drains, and near entry points.

The natural peppermint oil creates a scent barrier that discourages centipedes and many other crawling insects from crossing.

Step 5 — For Serious Infestations

If centipedes are appearing frequently in large numbers, a stronger approach may be needed. Sulguy Bifenthrin Concentrate is a professional-grade insecticide that creates a long-lasting barrier around your home's perimeter when diluted and applied correctly.

Always follow label directions and ventilate treated areas before re-entry.

How to Prevent Centipedes From Returning

Keep glue traps in place as ongoing monitors. Replace them monthly. A trap with no centipedes means your control methods are working.

Maintain a dry, clean home with sealed entry points. Centipedes need three things: moisture, food, and shelter. Eliminate any one of them and they will move on.
