What are you seeing?

Most people notice a sign before they see the pest itself. Find the closest match below.

  • Droppings

    Small, dark, rice-sized droppings (about 3 to 6mm) usually mean mice. Larger, capsule-shaped droppings (about 10 to 14mm) usually mean rats.

    Likely: Mice, Rats

  • Scratching in the loft, walls or floors

    Scurrying at night is usually rats or mice. Heavier thumping early in the morning and during the day points to grey squirrels.

    Likely: Rats, Mice, Grey squirrels

  • Gnawed wood, cables or packaging

    Fresh gnaw marks, chewed food packaging or damaged cables are a sign of rodents or squirrels, and a fire risk where cables are affected.

    Likely: Rats, Mice, Grey squirrels

  • Itchy bites when you wake up

    Bites in lines or clusters on the arms, neck or shoulders, with small dark spots on mattress seams, often mean bed bugs. Bites around the ankles, especially with pets in the house, usually mean fleas.

    Likely: Bed bugs, Fleas

  • Insects flying in and out of one spot

    A steady stream of wasps going in and out of a gap in the eaves, an airbrick or a shed means a nest. Hairier, golden-brown insects, or a large cluster on a branch or wall, are likely honey bees.

    Likely: Wasps, Bees

  • Lots of slow flies in upstairs rooms

    Flies gathering at windows in lofts and upper rooms in autumn, or on warm spring days, are probably cluster flies.

    Likely: Flies

  • Small round holes in timber

    Holes about 1 to 2mm across, with fine powdery dust below, are the classic sign of woodworm. Fresh, pale dust suggests it may still be active.

    Likely: Woodworm

  • Holes in carpets, rugs or woollens

    Look for small, hairy brown larvae, known as woolly bears, at the edges of carpets, under furniture and in dark cupboards.

    Likely: Carpet beetle

  • Trails of small insects in the kitchen

    Black ants coming in from outside in summer are usually black garden ants. Tiny, pale ants in a warm building could be Pharaoh ants, which need professional treatment.

    Likely: Ants

  • Insects that run when the light goes on

    In kitchens at night, often with a musty smell, they may be cockroaches. Small, silvery insects darting away in a bathroom are usually silverfish.

    Likely: Cockroaches, Silverfish

  • Grey bugs near doors and damp walls

    Small, grey, armoured bugs on ground floors are woodlice, and usually a sign of damp nearby.

    Likely: Woodlice

  • Damage to lawns and gardens

    Mounds of soil and raised tunnels mean moles. Scrapes, burrows, grazed plants and small round droppings point to rabbits.

    Likely: Moles, Rabbits

  • Birds on the roof or droppings on ledges

    Droppings building up under ledges, solar panels or loading bays mean roosting pigeons. Large, noisy birds nesting on flat roofs and chimneys are usually gulls.

    Likely: Pigeons, Gulls
