Getting Bats Out of Your Colma Home

Bats in the attic of a Colma home are protected under many state and local rules, so the standard fix is not a trap or a sealed hole. Bats can use a gap narrower than a finger, so the technician walks the whole roofline at dusk to find every exit. The pest control company puts up one-way exits so the bats leave to feed at night and cannot get back in, and times the work around the season when young bats cannot fly. Once the colony is gone, the entry points are sealed and the guano is removed. Never touch a bat, because even a tiny bite may carry rabies.

Before the Exterminator Arrives

  • Never touch a bat with bare hands. Bats can carry rabies, and a bite can be so small you do not feel it. If a bat was in a room with a sleeping person or a child, or anyone was bitten or scratched, call a doctor or your local health department right away. Call 911 for serious symptoms.
  • Do not seal the hole. Closing the entry with bats inside traps them, and they may head into living areas looking for a way out. In summer it can also leave young bats that cannot fly to starve.
  • Keep pets and children away from the area. Do not let anyone sleep under an active roost. If a pet may have touched a bat, call your veterinarian, since rabies vaccines for pets need to be up to date.
  • Stay out of the attic and leave guano alone. Dry bat droppings can carry fungal spores, and stirring them up puts dust in the air. The company wears protective gear for cleanup. If you develop a cough or trouble breathing after exposure, see a doctor.

Signs You Need Bat Removal

  • Bats leaving at dusk. Watch the roofline around sunset. Bats leave to feed soon after dark and return before dawn, so several flying out of one spot is the clearest sign of a roost.
  • Dark stains around a small gap. Oily brown smudges around a gap in the fascia, a vent or the chimney come from fur oils. Bats can squeeze through openings smaller than most people expect.
  • Droppings below the entry. Guano looks like mouse droppings but is crumbly, with shiny bits of insect wings, and it breaks into dust when pressed. It piles up under the entry or in the attic.
  • High-pitched chirping and rustling. Soft squeaking or scratching in the walls and attic around dusk and dawn, and louder chirping in summer when pups are present, can mean a colony.
  • A strong, musty, ammonia-like smell. Guano and urine build up in the attic or upstairs rooms and can leave brown stains spreading across the ceiling.

Local conditions

Bat Removal in Colma: What to Know

California bats include Yuma myotis, big brown bats and large colony-forming species that squeeze into stucco gaps, tile roofs and eaves, and maternity-season limits apply on removal work. Bats are protected in most states, and many restrict removal while pups are in the roost (roughly May through August).

Calls about bat problems come from every Colma ZIP code, day and night.

How the Job Is Done

  • Find every exit. The technician watches the house at dusk, checks the roofline, vents, siding and chimney, and counts the bats leaving to find the main roost and every gap they use.
  • One-way exclusion. Netting or tubes let bats fly out to feed but block the way back, and other gaps are sealed. Many states limit this work while young are in the roost, so timing depends on state and local law.
  • Seal up and clean guano. After all bats have left, the exit is closed for good. Guano and soiled insulation are cleaned up or replaced, with protective gear and, where needed, disinfectant.

  • Any chirping, scratching, staining or smell in the attic, walls or ceiling.
  • Whether a bat has been inside the living space, or touched a person or pet.
  • What the roofline is like, such as siding, soffits, a chimney or a tile roof, and how old the house is.
