House centipedes tend to enter or remain where they find moisture, shelter, and other small arthropods to eat. Seeing an occasional individual does not necessarily mean a serious infestation. Reducing dampness, sealing entry points, and lowering other pest populations is usually more effective than chasing individual centipedes.
Look for moisture in bathrooms, basements, and utility areas
Condensation, leaks, and damp corners support both centipedes and the prey they eat. Repair leaks, improve ventilation, and use dehumidification when a space remains humid.
Reduce the other insects they feed on
Silverfish, small cockroaches, and other arthropods can support their presence. Cleaning, food storage, and exclusion reduce the whole pest chain rather than focusing only on the visible predator.
Seal cracks and gaps around service penetrations
Inspect baseboards, frames, floor joints, and pipe penetrations. Use materials appropriate to the gap and do not seal drains, ventilation openings, or required building vents.
Frequent sightings can signal a moisture or prey problem
If many appear for weeks, look for the condition keeping them indoors. Integrated pest management prioritizes correcting water, shelter, and food sources before broad chemical treatment.
