Where the Fluff Collects in a Sudbury House
Pull the plinth off the bottom of a run of kitchen units and you find a shallow, undisturbed tray of dust, hair and crumbs running the whole length of the room. The same thing sits behind a wardrobe that has never been moved, under a fitted cupboard, and in the gap under a built-in oven. Larvae a few millimetres long can spend months in there and only show up when one crosses a carpet in daylight. Where they hide around the home lists the rest of the places worth a torch.
The Garage, the Utility Room and the Shed
A Sudbury house usually has somewhere to put things that are not quite rubbish, and that is a carpet beetle's idea of a larder. Offcuts of old wool carpet kept in case of a repair, bags of clothes for the charity shop, camping gear, a sheepskin, a felt-lined tool roll — and, along every garage and shed window channel, a line of dead flies. Larvae feed on all of it, and every so often some of it is carried back into the house.
Nests in the Eaves and Over the Porch
Interwar timber eaves and soffits shrink and split, and starlings and sparrows use the openings; so does the gap above a porch or a bay roof, and the space under a garage or shed roof. With open ground and playing fields close by there is no shortage of birds. Once a nest is finished with, the feathers, down and dead insects in it feed beetle larvae for a long time, and the young beetles work downwards into the bedrooms through the loft hatch, ceiling roses and the tops of the walls. It is an offence to damage or destroy a wild bird's nest while it is being built or in use, so an active nest is left alone; when it is finished with, a roofer or builder clears it and closes the gap. Do not go up a ladder to do it yourself.
Beetles on the Windowsill in Spring
Adults feed on pollen outdoors, so when they emerge indoors they head for the brightest window they can find. That is why a bedroom sill, a landing window or the garage window fills up with small mottled beetles in April and May. Why they appear on windowsills explains the timing, and how to know if you have them covers the whole picture.
- Small round beetles patterned in brown, cream and black, most noticeable in spring
- Short brown larvae covered in bristles, usually along a carpet edge or under a bed
- Empty larval skins in drawers, on a wardrobe floor or under boxes in the garage
- Ragged holes in wool jumpers, blankets and the edges of carpet
Pale smooth larvae leaving fine webbing behind them are carpet moths in Sudbury instead; the two are compared here, and the damage is priced the same way either way.
The Bristles and Itchy Skin
The hairs on the larvae irritate some people's skin, which is why a rash in a bedroom with nothing at all on the mattress is sometimes carpet beetles rather than bites. This guide explains the difference. If you have a rash or other symptoms, speak to a pharmacist or GP, and call 999 if there are signs of a severe allergic reaction. If there is dark spotting along the mattress seams as well, check for bed bugs in Sudbury before assuming.
Booking and Getting the Rooms Ready
Tell us which rooms you have found larvae or damage in, whether you have watched birds going in and out of the eaves, and what is stored in the garage, the shed and the loft. Each affected room counts once; halls, landings and stairs are not counted. Before the visit, vacuum carpet edges, under beds and inside wardrobes in those rooms, empty the cleaner outside, and bag stored textiles where they are rather than carrying them through the house.
Adults can carry on appearing at the windows for a while afterwards, particularly in spring, and how long it takes to settle depends on the house and on whether the source outside has been dealt with. If you are finding new larvae once the time we give you has passed, call us again.
Keeping the Numbers Down in an Interwar Semi
- Once a nest is finished with, have the old material cleared and the eaves, soffit or porch gap repaired by a roofer
- Keep garage, shed and loft storage in sealed boxes rather than open bags, and lift it off the floor
- Take the kitchen plinths off once a year and vacuum the length of the run behind them
- Clear dead flies out of window channels, light fittings and the garage before spring
- Vacuum up the adults you find on sills instead of leaving them to find their way back in
