Because Laying Poison Is Only Half The Battle!
Hear a scratch at 2 a.m.? See one ant on the worktop? Notice a pin-sized hole in a wool jumper? Small signs often point to a bigger problem nearby.
Most pests start out of sight. They settle in cupboards, skirting gaps, lofts, and beds. They spread fast if you miss the first clues.
This guide covers the household pests UK homeowners meet most, how to spot them quickly, and what to do first. It draws on leading UK advice, plus field insight from CCS Environmental in London.
Below, you’ll find simple checks, clear fixes, and red flags you should never ignore. Catch them early and you stay in control.
Use this quick checklist before you call for help:
If you are unsure, keep a photo, note the room, and call a professional.
Listen for scratching in walls or under floors. Look for droppings and gnawed packaging. Rats and mice spread disease and breed quickly, so act fast.
What to do now: Seal gaps bigger than a pencil. Store food in sealed tubs. Clear refuse often. If activity continues, book a survey.
Black garden ants (Lasius niger) trail to sweet foods and often enter from patios and under paving. Nests sit under slabs and foundations. Pharaoh ants are tiny, yellow-brown, and can split into new colonies if treated the wrong way, so use the right bait strategy.
What to do now: Wipe trails, fix spills, and block entry points. Avoid random sprays for pharaoh ants; targeted gels are the standard approach.
UK homes most often see German cockroaches (small, tan, two dark head stripes) and Oriental cockroaches (larger, dark, prefer cool, damp areas). They hide behind fridges, in cupboards, and pipe voids. Control needs baits, growth regulators, and strict hygiene.
What to do now: Reduce moisture and clutter. Don’t spray randomly; it can scatter them. Book professional baiting and monitoring.
Look for bites on exposed skin, small blood spots on sheets, and dark specks (faeces) near mattress seams and headboards. Adults are about 5 mm and hide in cracks, fabric folds, and even behind pictures. DIY rarely clears an established issue.
What to do now: Bag bedding, wash hot, and vacuum slowly with a crevice tool. Arrange a professional heat treatment /chemical program if signs persist.
Bites are small, red bumps, often in clusters around ankles. Pets may scratch or show hair loss. Eggs and flea dirt can sit in carpets and pet bedding. Treat pets and the home at the same time to break the cycle.
What to do now: Wash pet bedding hot. Vacuum edges and under furniture daily during treatment. Use vet-approved pet products plus a home treatment plan.
Small, silver-grey, fast insects that love damp rooms like bathrooms and kitchens. They leave irregular holes or graze marks in paper, photos, and cardboard. Reduce humidity and fix leaks to push them out.
What to do now: Improve ventilation, run a dehumidifier, and seal cracks around skirtings and pipe entries.
