Flea & Tick Elimination
Flea & Tick Control in Pacifica, CA
101 Exterminators does flea and tick control in Pacifica across the whole property — interior, yard, and the crawl-space and deck openings wildlife uses — California licensed under SPCB Lic. #9119 since 2005. Cat fleas (Ctenocephalides felis) get no seasonal break in this climate. Ticks here are a Sweeney Ridge and San Pedro Valley trail problem far more than a backyard one.
Warning Signs
Signs You Need Fleas & Ticks Service in Pacifica
Inside the home we pair an adulticide with an insect growth regulator, which keeps eggs and larvae from ever reaching the breeding stage. Outside we treat the shaded ground where larvae survive, plus the fence lines, wood piles, and crawl space openings that wildlife uses as a highway. Tick work concentrates on the boundary between mowed yard and unmanaged brush, since that strip is where questing ticks meet people and dogs. We also walk the property for the entry points that keep bringing fleas back, and we explain what your veterinarian needs to handle on the animal, because the environment and the pet only work when they are handled together.

How It Works
Our Fleas & Ticks Process in Pacifica
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Pacifica.
Inspection & Source Identification
We look for flea dirt where it collects, check crawl spaces and the shaded ground under decks and hedges, and note where opossums, raccoons, and ground squirrels are moving through the property. For ticks we walk the line where kept lawn meets brush, since that strip carries most of the exposure. What the inspection turns up sets the treatment, rather than a standard package set in advance.
Interior Treatment
Interior work pairs an adulticide for the fleas you can see with an insect growth regulator for the ones you cannot. The growth regulator keeps eggs and larvae from developing into breeding adults, and it goes where eggs settle: carpet, the base of upholstered furniture, pet resting spots, and along baseboards. On hard floors we work the edges and cracks, where debris feeds developing larvae.
Yard & Property Edge
Flea larvae do not survive in open sun, so yard treatment targets shade: under decks and stairs, beneath dense shrubs, along the north side of the house, and wherever the dog lies down. Tick treatment follows a different line, the border where mowed yard gives way to tall grass, leaf litter, and brush. Treating the whole lawn misses both.
Pet Coordination & Follow-Through
Treating the house without the animal, or the animal without the house, puts you back where you started. We coordinate timing so your veterinarian's product goes on the pet the same day we treat, and we walk you through the vacuuming schedule that pulls pupae out of the carpet. Vacuuming does more than clean here, since the warmth and pressure signal cocooned adults to emerge onto treated surfaces.
Why 101 Exterminators
Fleas & Ticks You Can Count On in Pacifica
Growth Regulator in the Plan
An adulticide handles the fleas jumping today. The insect growth regulator works on the eggs and larvae buried in carpet and yard shade, which is where the great majority of the population is sitting at any moment.
Yard and Property Edge Treated
Indoor-only treatment leaves the outdoor source running. We treat the shaded ground where flea larvae survive and the brush line where ticks wait for a host to walk by.
Wildlife Source Assessment
Homes along open space, creek corridors, and farm edges get fleas delivered by opossums, raccoons, and ground squirrels. We find the openings those animals are using and tell you what needs closing.
Coordinated With Your Veterinarian
We time the visit around the product your vet has prescribed, and you get written prep and re-entry steps so the two halves of the job line up instead of canceling each other out.
Common Questions
Flea & Tick Control FAQs for Pacifica
We have no pets but keep finding fleas in our Pacifica house. Where are they coming from?
Wildlife under the floor is the usual answer. Raccoons, skunks and opossums den in crawl spaces, under decks and in garage gaps throughout Pacifica, especially on blocks near the creek corridors and the Golden Gate National Recreation Area open space, and cat fleas drop off wherever the animal rests. Once the host leaves or is excluded, the hungry fleas move up through the floor looking for a replacement. Sealing the crawl space and skirting the deck is the durable half of the fix.
Do we need to check for ticks after hiking Sweeney Ridge or San Pedro Valley?
Check every time, and check the dog too. Western black-legged ticks (Ixodes pacificus) sit on grass and low brush along the trail edges at Sweeney Ridge, Milagra Ridge, Mori Point and San Pedro Valley County Park, and they attach during the walk rather than in a mowed yard. Stay on the trail, then check ears, neck, waistline and legs before getting in the car. If one is attached, pull it straight out with fine-tipped tweezers and keep it in case identification matters later.
Do fleas die off over a Pacifica winter?
No — the population never crashes here. Winter lows in the mid-40s slow the cycle without breaking it, and indoor eggs and pupae keep developing on schedule regardless of the weather outside. That is why treating through winter matters more on this coast than it does inland, where a hard freeze does part of the work. In those months the interior treatment carries more weight than the yard treatment.
