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. In Palo Alto the source is often wildlife: opossums, raccoons and squirrels crossing yards from the creek corridors and the foothill preserves.

Local Context

The Fleas in a Palo Alto House Usually Belong to an Animal That Does Not Live There

Cat fleas (Ctenocephalides felis) are the species in almost every Palo Alto flea call, and they are not particular about the host. Opossums, raccoons, skunks and ground squirrels carry them, and those animals move through the city on established routes — the creek corridors along San Francisquito, Matadero, Adobe and Barron creeks, the mature back-yard canopy, and the open space edge at Pearson-Arastradero, the Foothills preserve and the Palo Alto Hills. A house with no pets can still get fleas, and that is usually where they came from.

The reason treating the dog alone fails is arithmetic, not effort. Adult fleas on an animal are a small share of the population; the eggs, larvae and pupae sitting in carpet, upholstery, pet bedding and shaded soil are the rest. Eggs roll off the host wherever the animal rests, which in a Palo Alto house means the sofa, the rug and the warm spot by the sliding door, and outside means shaded soil under a deck or a hedge. Pupae can wait weeks inside the cocoon and then hatch once the pet is back.

Ticks work differently and follow the trail system. Western black-legged ticks quest from grass tips and low brush along shaded trail edges, which is why dogs walked at Pearson-Arastradero or the Foothills preserve come home with them and dogs walked along Middlefield Road generally do not. Palo Alto's rain falls November through April and the vegetation stays green into early summer, so that is the window worth checking an animal carefully after every walk on the western edge.

How We Work in Palo Alto

We inspect the interior for where the animal actually rests, since that is where eggs and larvae concentrate, and treat those areas with an adulticide plus an insect growth regulator so the next generation never reaches breeding age. Outside we treat the shaded, protected ground under decks, hedges and sub-area openings rather than the open lawn, where fleas cannot survive anyway. Then we look for the wildlife entry: an open sub-area vent, a gap in a deck skirt, a crawl space an opossum has been using.

Palo Alto Climate

Palo Alto has warm summers and seasonal rain. Nearby creeks do not establish soil-foraging termites at a home.

Housing Stock

Older houses in Professorville and Crescent Park stand alongside later Palo Alto construction. The construction and later alterations determine which wood is visible.

Why Local Expertise Matters

In Palo Alto, preserving finishes matters when evaluating how concealed wood might be inspected or treated. Ask for the inspected areas, any limits, and the written basis for a treatment recommendation. A separate Section I/Section II report is available on request; the report itself does not decide a transaction’s repair terms.

Warning Signs

When to Ask About Flea & Tick Control 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.

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 Palo Alto

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 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.
