Flea & Tick Elimination
Flea & Tick Control in San Jose, CA
101 Exterminators handles flea and tick control in San Jose by treating the house and the yard, not only the pet — the adult fleas on an animal are a small share of the actual population. We are California licensed under SPCB Lic. #9119, Santa Clara County. Cat fleas (Ctenocephalides felis) are the species here, and the reservoir is usually shaded ground where wildlife crosses.
Home maintenance
How do you keep fleas and ticks away from a San Jose foothill home?
Keep wildlife from settling under the house and deck, protect every pet, and dry out the shaded parts of the yard. Homes in the East Foothills, Evergreen and above Almaden Valley back onto open space where raccoons, opossums and ground squirrels travel at night. With summers near 81 degrees and winter lows near 42, fleas stay active most of the year.
Close the space under the deck
Fit hardware cloth around decks, sheds and porch steps, buried a few inches into the soil, so wildlife can't den there. If your home has a crawl space, keep its vent screens intact and its access door closed.
Seal gaps under the back fence
Animals coming off Alum Rock Park, Joseph D. Grant County Park and Almaden Quicksilver dig under fences. Fill gaps under the back fence with buried wire or a gravel strip.
Dry the shaded fence line
Flea larvae survive the rainless months in irrigated shade. Rake leaf litter from north-facing fence lines and under shrubs, and keep sprinklers off the spot where the dog lies down.
Keep pets on a vet-recommended preventive
Ask your veterinarian which flea and tick product fits each dog and cat, and keep every pet in the household on it year-round.
Check after open space walks
After walks in the foothill parks, check yourself, children and dogs at the hairline, behind the ears and between the toes. Stay on the trail center, away from grass and brush.
When to do it
Pet protection year-round; seal decks and fences in spring, before the dry season concentrates fleas in shaded, watered ground.

Warning Signs
When to Ask About Flea & Tick Control in San Jose
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.
Pets scratching or chewing at the base of the tail, the belly, and behind the ears
Flea dirt in pet bedding: dark pepper-like specks that turn rust red on a damp paper towel
Bites in tight clusters on ankles and lower legs, usually a few in a row
Small dark insects that disappear into carpet pile the moment you part the fur
A burst of biting a day or two after a vacation, or on the first day in a vacant rental
Fleas in a home with no pets, which usually points to wildlife living under the structure
Ticks found on a dog after time in the yard rather than after a hike
An attached tick on a family member, or a rash, fever, or joint ache in the weeks after a bite
How It Works
What to Expect from Flea & Tick Control in San Jose
Tell us whether you have found fleas or ticks indoors, on pets or outside. We can discuss which areas need to be checked.
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
Why Choose 101 Exterminators for Flea & Tick Control in San Jose
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 Jose
Why do fleas keep coming back at my San Jose home even though the dog is treated?
Because the pet is the smallest part of the population. Adult fleas on the animal are a fraction of the total; the eggs, larvae and pupae sit in carpet, pet bedding, the crawl space and the shaded ground outside. If the yard reservoir goes untreated — particularly on properties backing open space in the East Foothills or above Almaden Valley — wildlife and the dog keep restocking the house. Treating pet, interior and yard inside the same window is what breaks the cycle.
Can I get fleas in a San Jose house with no pets?
Yes, and it usually traces to wildlife that nested under or inside the structure. Raccoons and opossums under a deck, feral cats in a crawl space, or roof rats in the attic all carry cat fleas, and when the animal leaves or is removed the hungry fleas move toward the nearest host indoors. The same thing happens after moving into a San Jose rental where the previous tenant had pets, since pupae can wait months and hatch on the vibration of new footsteps.
Do I need to worry about ticks in San Jose yards, or only on the trails?
Mostly on the trails. Western black-legged ticks live in leaf litter, grass edges and brush along the trail systems at Alum Rock Park, Almaden Quicksilver County Park and the Sierra Azul preserve edge, and they typically ride home on a dog or on clothing rather than establishing in an irrigated San Jose yard. Properties sitting directly against open space are the exception. Check dogs after hikes, keep the grass cut along the fence line, and clear leaf litter where the yard meets the brush.
