Flea & Tick Elimination
Flea & Tick Control in Palo Alto, CA
101 Exterminators does flea and tick control in Palo Alto by treating the environment rather than just the animal — interior treatment with an insect growth regulator, plus the shaded outdoor areas where eggs actually accumulate. We are licensed in California under SPCB Lic. #9119 since 2005. In Palo Alto the source is often wildlife: opossums, raccoons and squirrels crossing yards from the creek corridors and the foothill preserves.
Warning Signs
Signs You Need Fleas & Ticks Service in Palo Alto
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 Palo Alto
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Palo Alto.
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 Palo Alto
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 Palo Alto
I have no pets. Why does my Palo Alto house have fleas?
Because a wild animal has been resting under or against the structure. Opossums, raccoons, skunks and squirrels all carry cat fleas, and a den under a deck, in a sub-area or in a shed puts eggs and larvae right against the building — when the animal leaves or dies, the hungry adults move indoors looking for a host. This is common in Palo Alto near the creek corridors and along the Pearson-Arastradero and Foothills edge. Closing the sub-area and deck access is what stops it recurring.
Do I need to treat the whole yard for fleas in Palo Alto?
No — open sunny lawn is one of the worst places for flea larvae, which dry out and die in direct sun. Treatment targets the shaded, humid, protected ground: under decks and stairs, along hedges and fence lines, the sub-area opening, the dog's resting spot in the shade, and anywhere wildlife travels. That keeps the treated area small and puts the product where the life stages actually are. We walk the yard and mark those areas before anything is applied.
Are ticks a real risk on the Palo Alto foothill trails?
Yes, on the western trails specifically. Western black-legged ticks (Ixodes pacificus) quest from grass tips and low brush along shaded trail edges at Pearson-Arastradero, the Foothills preserve and in the Palo Alto Hills, and this is the species associated with Lyme disease transmission in California. Check dogs and yourself after every walk on that side of the city — behind the ears, in the groin, and between the toes on a dog. Remove an attached tick with fine-tipped tweezers, close to the skin, straight out.
