Fleas in the San Gabriel Valley
Fleas ride in on pets and wildlife, then breed in the carpet and yard. Here's how to spot them, the bites they leave, and why the home and pet are treated together.
- Tiny (about 1/8 inch), dark, flat-bodied, wingless
- Jump remarkably far when disturbed
- Itchy bites clustered around ankles and lower legs
- “Flea dirt” (black specks that turn red when wet) in pet fur
- Worse in warm, humid stretches
What they look like
Fleas are tiny — about 1/8 inch — dark reddish-brown, and flattened side to side so they slip through fur. They have no wings but powerful back legs that let them jump many times their length, which is usually the first thing people notice: a small dark speck that vanishes with a leap.
The one in nearly every SGV home is the cat flea, which despite the name bites cats, dogs and people alike. You rarely see a single flea clearly; more often you see the evidence — bites on your ankles and “flea dirt” in a pet's coat.

Where they live
Adult fleas live on the animal, but most of a flea population — the eggs, larvae and pupae — lives off the host: in carpet, rugs, upholstery, pet bedding and the cracks of hardwood floors. Outdoors they wait in shaded, moist spots where pets and wildlife rest, like under decks, in crawlspaces and along fence lines.
That hidden, off-host majority is why fleas are so stubborn. Treating only the pet leaves the carpet and yard full of developing fleas that hatch days later, which is why the problem seems to come back.
Signs of a problem
The usual first sign is your pet scratching, biting or grooming more than normal, often with red, irritated skin at the base of the tail. Parting the fur may reveal fast-moving fleas or “flea dirt” — black, pepper-like specks of droppings that turn rusty red on a damp paper towel.
People notice small, intensely itchy bites, usually in clusters around the ankles and lower legs. Seeing fleas hop off carpet or pet bedding, especially in warm weather, confirms it.
How they are controlled
Fleas are a two-front problem: the pet and the home have to be handled together. Your veterinarian's flea preventive treats the animal; treating the home and yard handles the eggs, larvae and pupae the pet treatment can't reach. Skip either side and the cycle restarts.
Thorough, frequent vacuuming (then emptying it outside) and washing pet bedding remove a lot of the developing fleas, and a targeted treatment of the carpet, resting areas and shaded yard spots breaks the cycle. Since fleas often arrive with rodents and wildlife, sealing those out helps too. Ask us for a free quote if an infestation has taken hold.

Quick Answers
Quick Answers.
Why do I have fleas if my pet is on flea medication?
Flea preventives kill fleas on the animal, but most of the population — eggs, larvae and pupae — is in your carpet, bedding and yard, not on the pet. Those keep hatching for weeks, so the home and yard need treating alongside the pet preventive.
Can I get fleas without having a pet?
Yes. Fleas come in on rodents, opossums, raccoons, feral cats and even on your own clothing from an infested area. A home that backs onto wildlife or had a rodent problem can get fleas with no pet of its own.
Do flea bites on people look different?
Flea bites on people are small, red and very itchy, usually in clusters or lines around the ankles and lower legs — the areas easiest for a jumping flea to reach. They differ from mosquito bites, which tend to be larger, single welts.
How long does it take to get rid of fleas?
Because of the egg-to-adult cycle, it usually takes a few weeks and sometimes a follow-up. Treating the pet and home together, plus frequent vacuuming and washing bedding, is what shortens it. Treating only one side is what drags it out for months.
Are fleas a health concern?
For pets, heavy flea loads can cause skin allergies, hair loss and anemia, and fleas can carry tapeworm. For people the main issue is itchy bites and the occasional reaction. It's worth handling promptly rather than waiting it out.
How do I keep fleas from coming back?
Keep pets on a year-round vet preventive, vacuum often and wash bedding, and reduce the shaded, moist yard spots where fleas and wildlife rest. Sealing out rodents and other animals that carry fleas in is the last piece.
