Centipede and millipede control in South San Francisco is a damp-ground story. The irrigated landscaping, the leaf litter, and the moist soil around the older homes keep the population supplied, and the fall rains push both pests toward the structures. The house centipedes move indoors through the foundation gaps, and the millipedes gather in the large numbers at the door thresholds and the weep holes.

The two pests need different handling. The house centipede is a beneficial predator, and the control program is about the moisture and the harborage rather than eliminating it outright. The millipede is a nuisance feeder that invades in the mass after the rains, and the barrier treatment and the harborage removal are the main defense.

Signs of centipedes and millipedes in a South San Francisco home

  • Fast, leggy insects darting across the bathroom and the bedroom floors at night — the house centipede activity, most visible in the evening.
  • Slow, segmented insects crawling across the foundation and the door thresholds — the millipede activity, most common in the fall after the rains.
  • Millipedes gathered in the garage, the basement, and the porch — the mass invasion at the damp, sheltered entry points.
  • Large numbers on the exterior foundation walls and the walkways — the fall migration of the millipedes toward the structures.
  • Curled-up dead millipedes in the corners and the doorways — the pest activity after the mass migration.
  • Centipedes in the damp bathroom, the laundry room, and the basement — the house centipede following the moisture and the prey.

Why South San Francisco homes get centipedes and millipedes

The moisture is the headline. The coastal climate, the irrigated landscaping, the leaf litter, and the mulch keep the soil and the harborage damp through the year, and both pests need the moisture to thrive. The fall rains push the moisture higher, and the millipedes in particular move toward the drier structures in the large numbers.

The landscaping and the housing stock add the second layer. The established beds, the mulch, and the leaf litter give the millipedes the breeding habitat, and the older homes have the foundation gaps, the weep holes, and the damp basements that let both pests indoors. The program has to cut the harborage, correct the moisture, and treat the entry points together.

How we treat centipedes and millipedes in South San Francisco

  1. Inspection and harborage mapping. We walk the beds, the mulch, the leaf litter, the foundation line, and the indoor moisture areas, identifying the harborage and the entry points.
  2. Exterior barrier treatment. We treat the foundation line, the beds, and the perimeter where both pests travel and gather.
  3. Harborage reduction. We remove or treat the mulch, the leaf litter, and the debris that shelter the millipedes and the centipedes.
  4. Moisture correction. We address the overwatering, the leaky spigots, and the drainage issues that keep the ground damp.
  5. Indoor treatment and sealing. We treat the damp interior areas and seal the foundation gaps, the weep holes, and the door thresholds.

Preventing centipedes and millipedes in South San Francisco

  • Pull the mulch and the leaf litter away from the foundation. The damp harborage is the source, and the clearance cuts the population.
  • Rake the fallen leaves before the fall rains. The leaves hold the moisture and shelter the millipedes, and the removal cuts the mass migration.
  • Fix the leaky spigots and the drainage. The damp ground keeps both pests active, and the dry conditions cut the pressure.
  • Seal the foundation gaps, the weep holes, and the door thresholds. The entry points are the route indoors, and the sealing closes them.
  • Keep the garage and the basement dry. The damp, sheltered spaces hold the population, and the dehumidifier and the ventilation cut it.

In the years we’ve treated the Bay Area, the South San Francisco millipede calls are almost always a fall rain story. The homeowner wakes up to the hundred millipedes on the porch and thinks the house is infested, but the mulch bed along the foundation has been breeding them all summer, and the first rain pushes them toward the dry walls. The mulch pull-back and the foundation barrier in the September stop the October invasion.

Frequently Asked Questions

Are centipedes and millipedes a problem in South San Francisco?
The house centipedes and the millipedes show up in the older homes and the damp landscaping. The house centipede is the faster, leggier predator that feeds on the other pests, while the millipede is the slow, segmented feeder that moves indoors after the heavy rains and the fall cooling.
How much does centipede and millipede control cost in South San Francisco?
A treatment runs $120 to $300 depending on the home size and the harborage areas. The combined exterior treatment and the moisture correction typically land between $250 and $600.
Are house centipedes dangerous?
No. The house centipede is a beneficial predator that feeds on the other pests like the roaches, the silverfish, and the spiders. The bite is rare and mild, and the control program targets the damp harborage and the moisture, not the centipede alone.
Why do the millipedes invade my house every fall?
The millipedes breed in the damp leaf litter and the mulch, and the fall rains and the cooling push them toward the drier structures. The large numbers gather on the foundations and move indoors through the gaps and the weep holes, and the barrier treatment and the harborage removal cut the pressure.
Do you treat the damp areas and the landscaping together?
Yes. The centipede and the millipede problem starts in the damp mulch, the leaf litter, and the foundation beds. We treat the exterior harborage and the foundation line, correct the moisture issues, and treat the indoor entry points together.
