Flea & Tick Elimination
Flea & Tick Control in San Carlos, CA
101 Exterminators does flea and tick control in San Carlos with an interior treatment built around a growth regulator, plus outdoor work where wildlife actually travels — California licensed, SPCB Lic. #9119, since 2005. Cat fleas (Ctenocephalides felis) ride in on opossums, raccoons and ground squirrels whether or not you own a pet, and the properties along the open-space edge get restocked all summer.
Warning Signs
Signs You Need Fleas & Ticks Service in San Carlos
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 San Carlos
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in San Carlos.
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 San Carlos
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 San Carlos
Why does my San Carlos house have fleas when I do not own a pet?
Wildlife brought them. Cat fleas infest opossums, raccoons, feral cats and ground squirrels, all of which move through San Carlos yards — especially along the western edge where the canyon parkland meets residential fences. If one of those animals has been denning under a deck, a shed or through an open crawl vent, eggs and larvae accumulate in that void and adults work their way indoors. Closing off the denning space is as important as the treatment.
We walk our dog at Edgewood Park — how do we keep ticks out of the house?
Check the dog before it comes inside, every time, focusing on the ears, neck, armpits and between the toes. Ixodes pacificus waits on grass and low brush at the trail edge, so it transfers on contact rather than dropping from trees. At home, keeping the fence-line grass cut and the leaf litter cleared removes the yard habitat, and your veterinarian can advise on a preventive product for the animal. Yard treatment targets that shaded edge, not the open lawn.
Why did fleas come back a couple of weeks after treatment in my San Carlos home?
Almost always pupae. The pupal stage is protected inside a cocoon that resists treatment, and it hatches on vibration and warmth days or weeks later — so a second wave after an initial knockdown is expected, not a failure. Vacuuming daily during that window triggers hatching and removes the emerging adults. The growth regulator applied in the first visit is what prevents that second generation from breeding, and a follow-up visit covers what is left.
