Flea Control in Gaithersburg, MD

Why do fleas come back after one treatment?

Because the pupal stage resists treatment and emerges over weeks. A treatment kills adults and reaches larvae, but pupae in carpet and soil hatch on their own schedule, triggered by warmth and vibration. A follow-up visit and steady vacuuming are part of the plan rather than an admission of failure.

This is also why the reinfestation story is so common after a holiday. The house sits quiet, pupae hold, and the family walks back in and triggers a mass emergence. Vacuuming hard in the days after treatment is genuinely useful because it brings pupae out early.

The other reason for a relapse is a treated house and an untreated animal, or the opposite. The two halves have to land in the same week.

What do I need to do before the technician arrives?

Vacuum every floor the pet uses, including under furniture and along skirting edges, and empty the vacuum outside. Wash pet bedding and any blankets or cushions the animal lies on at the hottest setting the fabric allows. Clear toys, shoes and clutter off the floor so treatment can reach it.

Think about where the animal rests rather than where you spend time. The dog's corner by the back door, the cat's chair, the spot at the bottom of the stairs and the base of the sofa are where eggs and larvae concentrate.

Do not shampoo or steam-clean carpets straight after treatment, because that can lift what was just applied. Ask the technician when wet cleaning can resume.

• Vacuum all carpets, rugs and floor edges, then empty the vacuum outdoors
• Wash pet bedding and soft furnishings the animal uses on the hottest safe setting
• Clear floors, including under beds and behind furniture where possible
• Arrange the vet's treatment for the animal around the same time
• Tell the technician about fish tanks, birds, reptiles and bee hives
• Plan to keep vacuuming for the following few weeks

Can I get fleas without owning a pet?

Yes. A property with a previous pet, a shared wall in a townhouse or apartment, a crawl space or shed that animals use, and visiting animals in the yard can all supply fleas. In a vacant property the pupae simply wait, which is why new occupants sometimes get bitten in week one.

This is a regular pattern in rentals and in houses being sold. Nobody has seen a flea for weeks because nothing has been walking on the carpet, and then the moving boxes arrive.

In a multi-unit building the source may not be your unit at all. Our apartment pest control page covers how work in shared buildings is coordinated, and the county's Department of Housing and Community Affairs enforces housing maintenance standards under Chapter 26, with tenants directed to MC311 for pest complaints.

Does the yard need treating as well?

Often, but only parts of it. Fleas outdoors survive in shade and moisture: under a deck, beside a crawl space vent, in the kennel, in the shaded soil along a fence. Open sunny lawn is poor flea habitat, so broadcast lawn spraying is both unnecessary and not what the local rules are written for.

Montgomery County restricts cosmetic pesticide use on private lawns, with products aimed at stinging and biting insects and at disease carriers such as mosquitoes and ticks reported exempt. The exact code language was not sourced here, so ask the technician what applies to your property before work is booked. The county's Department of Environmental Protection publishes the exemptions.

Where the yard backs onto woods or parkland there is usually a tick question alongside the flea one, and the two often get handled together. The tick control page covers the edge work that involves.

What moves the price of flea work?

The number of rooms and the amount of carpet, how long the infestation has run, how many animals are involved, whether outdoor areas and a crawl space are included, how much preparation is done before the visit, and how many follow-up visits the plan needs. The price is confirmed on site.

Preparation genuinely changes the job. A house vacuumed through, with bedding washed and floors clear, lets a technician treat properly in one pass. A house where furniture cannot be reached takes longer and works less well.
