IdentificationHow to Identify Fleas

Quick Answer

Fleas are tiny dark reddish-brown insects, about 1.5 to 3.3mm long, with flat side-to-side bodies built to slip through pet fur. They don't fly, but they jump up to 150 times their body length, which is how they get from your carpet to your ankle in one hop.

Full identification notes

Bites show up as small red dots, usually in clusters or lines on ankles and lower legs.

Fleas Behavior & Habits

Understanding how fleas behave helps prevent infestations

Adult fleas live on a host (dogs, cats, raccoons, deer) and rarely leave once they're settled in.

More about their habits

Eggs drop off the host into carpets, pet beds, and shaded spots in the yard, then hatch into larvae that hide in protected places. The tricky stage is the cocoon. Pupae can sit dormant for months and only wake up when they sense vibration, body heat, or CO2. That's why families moving into a vacant home sometimes get hit with a flea outbreak the first week.

Fleas Risks & Dangers

What fleas can do to your health and property

Health Risks

Flea bites itch badly and can trigger allergic reactions in people and pets.

Property Damage

No structural damage, but a real infestation means treating the home interior AND the yard.

Full health and property details

Health Risks

They also transmit murine typhus and tapeworms, which can pass to humans (especially kids who play on the floor). Heavy infestations on a small dog or cat can cause anemia, so don't wait if your pet is scratching nonstop.

Property Damage

Half-measures leave the lifecycle running.

Fleas in Boise & the Treasure Valley

In the Treasure Valley we see flea calls peak in late summer and early fall, especially in homes along the Boise foothills, Eagle's wildland edges, and Garden City lots that back up to the greenbelt or canals.

More on what we see locally

Pets pick fleas up from raccoons, feral cats, and deer passing through these yards. Idaho winters slow fleas down but won't wipe them out. Eggs and pupae sitting in carpet or protected outdoor spots ride right into spring.

Our Solution

How We Handle Fleas

What our approach looks like

Flea control takes a few fronts at once: your pets (through your vet), daily vacuuming indoors to pull out eggs and larvae, and the yard where eggs and larvae hide.

Our full approach

Our Lawn & Mosquito Program treats the yard monthly from May through October and covers fleas, ticks, and mosquitoes. Pricing is by lot size, starting at $69 a month for lots up to 0.25 acre, and it's 10% off when you bundle it with general pest control. Pupae are protected inside cocoons and keep emerging for weeks, so one treatment alone won't finish the job.

Fleas Questions Answered

Common questions about identification, prevention, and treatment

Call (208) 297-7947

Why do I still have fleas after treatment?

Quick answerFlea pupae sit inside protective cocoons that shrug off most treatments.

They keep emerging for 2 to 4 weeks after the first service, which is why one visit isn't enough. Stick with the schedule and keep vacuuming daily to trigger pupae early, and the cycle breaks.

Can I get fleas without pets?

Quick answerYes.

Fleas hitch in on wildlife passing through the yard, on used furniture, or from previous occupants' pets. We see this most often in Boise rentals and Garden City homes near the greenbelt. The pupae can wait months for a warm body to walk in.

When is flea season in Boise?

Quick answerFlea pressure in the Treasure Valley climbs from June through October, with the worst weeks usually in August and September.

Pets pick them up from wildlife during warm months. Indoors, where it stays heated year-round, an infestation can keep running through winter if it isn't treated.
