Flea Treatment in Bakersfield

If your dog or cat is scratching and you are finding bites around your ankles, you almost certainly have cat fleas, which the UC Statewide IPM Program calls the most common external parasite on both cats and dogs. Here is how fleas live, what a full treatment looks like, and how to keep kids and pets safe while you do it.

The flea life cycle, and why it matters

The adult fleas you see on the pet are only one stage. The others are eggs, larvae and pupae, found in carpet and pet bedding or in shaded spots outside. UC IPM gives this timeline:

• Eggs hatch in about 2 to 5 days.
• Larvae crawl and feed for 8 to 15 days, then spin cocoons and pupate.
• Fully formed fleas can wait inside the cocoon for up to 12 months when it is cool.
• At normal room temperature, the whole cycle can finish in about 18 days.
• Adults live about 30 to 40 days on the host.

The cocoon is the problem stage. UC IPM says sprays with an insect growth regulator kill larvae but not pupae, so "fleas will continue to emerge for about 2 weeks after treatment." Warmth and pressure from footsteps or a vacuum trigger them to come out. That is why people often think a treatment failed when it is working on schedule.

If you are not sure the bites are fleas, a photo of the bug can help a technician confirm it.

Step one: treat the pet

Treating the pet is the step that stops reinfestation. UC IPM says treating the pet normally prevents fleas from coming back in from outdoors. Talk to your veterinarian. UC IPM lists oral products such as lufenuron, nitenpyram and spinosad, some of which are FDA-registered veterinary drugs that need a prescription, plus spot-on products sold by vets and in stores.

Pet safety is where people get hurt. UC IPM warns that "not all products are safe for all animals" and that products containing permethrin or amitraz "never should be applied to cats." Do not put a dog product on a cat, and read every label. Treat every dog and cat in the household at the same time; an untreated pet keeps feeding the cycle.

Step two: treat the house

UC IPM recommends these steps, and they are where most of the work is:

1. Vacuum floors and carpets daily or every other day, along with upholstered furniture, focusing on where pets sleep.
2. Wash pet bedding in hot, soapy water at least once a week.
3. Wash throw rugs. Infested carpets can be treated with a spray that contains an insect growth regulator.
4. Keep vacuuming for 10 days to 2 weeks after treatment, since that pulls out adults as they emerge.
5. Do not retreat right away. UC IPM advises waiting at least several weeks before a second application.

A licensed technician will usually handle the indoor application and tell you how long to keep kids and pets off treated floors. Follow those re-entry instructions exactly.

If you are fighting fleas in more than one room, an inspection is a good next step.

Step three: the yard, only where it counts

UC IPM says outdoor sprays are seldom needed unless many adult fleas are present, and "it is seldom necessary to treat the entire yard or lawn areas." Focus on the shaded, protected spots where pets rest: under decks, along the north side of the house, in a dog run. I would not pay for a whole-yard spray for fleas unless a technician finds heavy activity across the yard.

Why one treatment is rarely enough

Three reasons. The pupae survive the first application and keep hatching for about two weeks. An untreated pet keeps bringing new fleas in. And in a warm house the cycle can turn over in about 18 days. This Old House also notes that "a single-visit treatment often isn't enough" for moderate to severe cases and that exterminators often schedule follow-ups. Ask whether a follow-up visit is included in the quote.

Can you handle fleas yourself?

Sometimes. The core of the UC IPM approach costs little. It is a vet-recommended product on every dog and cat plus daily vacuuming, along with hot washes of pet bedding for at least two weeks. If you caught it early and the bites are limited to one room, I would start there. I would call a licensed company when people are getting bitten in several rooms, when the house has carpet throughout, or when two to three weeks of that routine has not cut the numbers. In that case, the pest company handles the home and your vet handles the pet. Neither one replaces the other.

Are fleas a health risk?

UC IPM says cat fleas can transmit a typhus-like illness to people, called cat flea rickettsiosis, and they are intermediate hosts of dog and cat tapeworms, which children occasionally pick up. That is a reason to treat promptly, especially with young kids crawling on carpets where pets sleep.

What flea treatment costs

This Old House (updated April 2026) puts professional flea extermination at $75 to $400 per visit in most cases nationally, with professional spraying at $150 to $350 and whole-house treatment at $300 to $800. These are published national figures, not our quote. Ask for a quote before any treatment. More pest prices are in our pest control cost guide.

Getting help

We only refer companies licensed by the California Structural Pest Control Board, and you can verify a license yourself. If bites continue after the fleas are gone, ask the technician to check for bed bugs. If rodents or strays are bringing fleas in, see rodent control.

Ask a licensed local company to inspect and quote a plan.
