FLEA CONTROL IS EASY AS 1-2-3!

1. Keep them out

  • Frequently vacuum floors, carpets, and furniture
  • Wash pet and human bedding
  • Regularly clean or caulk cracks and crevices in floors and baseboards

2. Monitor

  • Use flea traps to monitor your household
  • Check your pet for fleas using a flea comb and a dish of soapy water, which will also get rid of any adult fleas

3. Treat your pets

  • Wash your pet with pesticide-free shampoo and warm water
  • Instead of topical treatment, ask your veterinarian if oral treatment is an option

Flea facts

Fleas make pets and people uncomfortable, and can transmit tapeworms to pets and sometimes to children. Fleas in your home spend the vast majority of their lifetime — up to 18 months — as eggs, larvae or pupae, not as biting fleas on your pet. Adult fleas can live on your pet for up to 40 days and females lay 20-50 eggs every day, which means flea problems can get out of control quickly, especially in warmer weather when fleas are more active. This is why getting rid of all life stages of fleas by vacuuming and washing pet bedding — not just getting rid of adult fleas — is needed to prevent or stop a flea infestation.

Finding fleas in the home

  • Adult fleas spend much of their time on an animal’s body. If you haven’t seen fleas but your dog or cat is scratching, your pet may have fleas.
  • You may be able to see tiny white flea eggs and white, worm-like flea larvae on the floor, in cracks and crevices, in carpets, and where pets rest or sleep. You may also see “flea dirt” (flea droppings) where your pet sleeps. These black specks contain blood, and turn red when wet.
  • Use a light trap to monitor your home for fleas. Light traps attract fleas and trap them on sticky paper. Traps work better if people and pets are not around — fleas prefer warm bodies to traps.

PreventingFleas

In your home

The vast majority of fleas (in several life stages) live throughout your home rather than on your pet. Therefore indoor flea prevention is a key part of flea control.

  • Frequently vacuum carpets, floors, couches, and chairs to pick up adult fleas, larvae, and eggs. Empty vacuum or dispose of bags in the trash, outdoors.
  • Frequently wash pet bedding in hot soapy water.
  • Thoroughly clean cracks and crevices in floors or baseboards, or permanently seal with caulk..
  • Blow or hand dust diatomaceous earth (DE) into cracks and crevices. Use DE labeled for use on pests, or use “food-grade” DE; avoid swimming pool DE. Wear a dust mask and goggles to keep DE out of your lungs and eyes. 
  • Avoid using indoor foggers as the pesticides transfer onto you, your clothing, and indoor surfaces. Upon washing, these pesticides go down the sewer drain and impact water quality. 
On your pet
  • Wash your pet with a pesticide free pet shampoo and warm water. Avoid shampoos containing the pesticide bifenthrin. When bifenthrin ends up in our waters, it harms crustaceans, aquatic insects, and fish.
  • Use a flea comb (available at pet stores) to remove adult fleas on your cat or dog. Drown fleas caught in the comb in a cup of warm soapy water and flush
    or pour down the drain. Make sure to comb well around your pet’s neck and base of the tail.
  • Ask your veterinarian if chewable (oral) flea medications are an option for your pet. These products are safer for the environment than indoor foggers and topical (“spot-on”) pet treatments, sprays and collars.
  • If you use spot-on flea treatments, avoid products that contain fipronil, bifenthrin, imidacloprid, indoxacarb, deltamethrin, or permethrin — chemicals that cause water quality programs in creeks, rivers, or bays, and the ocean.
Outdoors
  • Don’t treat for fleas outdoors unless you know you have a major problem there. Spray insecticidal soap only in those areas where you find fleas. 
  • Apply beneficial nematodes (H. bacteriophora or S. carpocapse) to soil where you have found fleas. Soil temperature must be between 60 ̊F and 90 ̊F, and the soil should be moist. Water before and after application, but don’t soak the area.

Using Pesticides Indoors Isn't Healthy for You, Your pets, or the Environment

Pesticides used on your pet or throughout your home transfer onto you and indoor surfaces around your home. For example, exposure to fipronil — a common ingredient in many spot-on topical treatments — may lead to adverse human health impacts to those applying the treatment and to children (California Department of Pesticide Regulation, 2023).

When washing pets, bedding, clothing, and your hands, these pesticides go down the sewer drain and impact water quality. Wastewater treatment plants cannot fully remove complex chemicals like pesticides. Wastewater agencies are concerned that pesticides in spot-on flea treatments can wash off a pet — even weeks after being applied — and end up in California waterways.
