Pest Control in City of Westminster

It depends on the pest. Wasp nests and one-off ant trails are usually solved in a single visit. Cockroaches, bed bugs, fleas and rodents almost always need 2-3 visits, because eggs laid before the first treatment hatch after it. Ask upfront whether follow-up visits are included in the quoted price.

For standard sprays and gels, you typically only need to stay out of treated rooms for 2-4 hours until surfaces dry. Fogging or flea treatments may require 4-6 hours away. Whole-structure fumigation (rare, mostly for termites or severe bed bugs) means vacating for 1-3 days. Your technician must give you re-entry instructions — ask if they don't.

Clear access to skirting boards, under sinks and behind appliances; store open food and utensils away; note where and when you've seen pests (photos help); secure pets and cover fish tanks. For bed bug jobs, follow the company's prep sheet exactly — bagging laundry and decluttering — or the treatment can fail.

That's usually the flush-out effect: insecticides drive insects out of harborage areas, so activity spikes for 1-2 weeks before dropping sharply. If you're still seeing live pests after 2-3 weeks, call the company back — most guarantee retreatment within 30-90 days.

Professionally applied products are used at low concentrations and are generally safe once dry, but ask the technician for the exact product names and labels before treatment. Keep children and pets off treated surfaces until dry (usually 2-4 hours), cover aquariums, and mention pets in advance — some treatments (e.g. certain flea products near cats) need adjusting.

Termites have straight antennae, a thick uniform waist, and two pairs of wings of equal length; ants have elbowed antennae, pinched waists and unequal wings. Mud tubes on foundations, hollow-sounding timber and piles of shed wings near windows point to termites — get a professional inspection quickly, since termite damage compounds.

Some councils still offer free or subsidised treatment for public-health pests (rats, mice, bed bugs), but many have cut services or charge £50-£150 per course. Check your council's website first — where the service exists it's often cheaper than private firms, though waiting times are longer.

Wasp nest treatment is one of the cheapest pest jobs at roughly £45-£120, typically around £70. Beware of national call-centre firms quoting £150+ for the same 20-minute job — local BPCA members are usually cheaper.
