How to maintain the yard to prevent centipedes?

The yard acts as a transit point for centipedes entering the house. Proper yard maintenance reduces them at the source. The key is to eliminate hiding places and food sources.

Remove yard debris

• Bricks, tiles, and stones stacked against walls are favorite hiding spots; move them away from the wall or elevate them.
• Keep firewood and logs at least 30 cm away from the exterior wall.
• Turn unused flower pots and buckets upside down to prevent standing water and insect harborage.
• Regularly clean tool sheds and storage areas; do not leave clutter on the floor.
• Remove or discard old wood, metal sheets, and plastic sheeting promptly.
• Centipedes lay eggs in May-July; focus on yard clearing in late spring to reduce breeding opportunities.

Plant and lawn management

1. Lawn, mow regularly to keep grass height below 10 cm. Dense, thick grass creates damp, dark conditions favorable for centipedes and their prey.
2. Plants near walls, avoid dense planting along the foundation; leave a 30-50 cm clear zone.
3. Leaf litter removal, sweep up leaf piles in corners promptly; do not leave dead branches around the foundation.
4. Mulch, do not apply bark or straw mulch too thickly; turn it over periodically to prevent moisture buildup underneath.

Foundation and wall maintenance

• Fill foundation cracks with cement or expanding foam to prevent entry.
• Check exterior wall openings for air conditioner pipes and electrical conduits; seal gaps with foam.
• Keep drainage ditches clear to prevent leaf blockage and standing water.

Combine with chemical control

After yard cleaning, spray bifenthrin-containing household insecticide around the foundation, wall bases, and door frames to form a chemical barrier. Cleaning + spraying gives the best centipede prevention.
