How to Get Rid of Carpet Beetles in a Greenwich Property

Two Halves, and Most Treatments Only Do One

The first half is the rooms: treatment to floor perimeters, beneath furniture, along skirting lines and into affected drawers, wardrobes and storage. That deals with the larvae currently causing damage and it is necessary.

The second half is the search. Loft where it is accessible, eaves, airing cupboards, chimney breasts, and every stored textile in the property. That is what decides whether the first half lasts.

Treating the floor beneath a reservoir buys a few good months. It does not outlast the reservoir.

What the Search Is Looking For

• Old bird nesting material in the eaves, a roof void or a disused chimney. The classic, and full of feathers.
• Old wasp or bee nests in a roof space, which leave the same kind of debris.
• Stored wool - blankets, throws, jumpers, a rolled rug.
• Sheepskin, felt and hides.
• Feather-filled items - pillows, duvets, cushions.
• Anything natural-fibre that has been in a loft or a cupboard for years without being looked at.

Three Outcomes, and Which One You Are In

1. No reservoir, or an accessible one. The commonest case. Rooms treated, source dealt with, done. The published room price is the whole cost.
2. A reservoir in an accessible loft. Also common. Removing old nesting material is usually straightforward once it has been found, and finding it is part of the survey.
3. A reservoir behind a sealed roofline or in an inaccessible eaves space. Here the honest answer is that reaching it is roofing work, not pest control. We will describe what we believe is up there and where, and a roofer will quote it separately. We are not going to keep treating the carpet underneath it.

Before the Visit

1. Vacuum edges, under furniture, and inside affected drawers and wardrobes, then empty the vacuum into an outside bin.
2. Move furniture where you can, so the perimeter can be reached.
3. Bag damaged items rather than carrying them from room to room.
4. Do not clear the loft. Leave anything up there where it is until it has been looked at - carrying old material down through the house distributes the problem.
5. Gather what you have found - a shed skin in a pot, a photograph of the holes - so identification is settled quickly.

What to Do With Affected Items

• Washable wool and natural fibres: the hottest wash the fabric allows.
• Items that cannot be washed: professional cleaning, or freezing for a sustained period where the item can take it.
• Badly damaged items: bag and dispose of them rather than storing them elsewhere in the property.
• Feather-filled items near the damage: worth checking even if they look fine, because they are a food source in their own right.

Afterwards

Leave treated floors and cupboards alone for the period we specify on the day. Cleaning removes the treatment before it has dealt with what is still to emerge.

After that, the ongoing measures are the same ones that work against carpet moth: vacuum the edges and under the furniture regularly, move things occasionally, and do not let stored wool sit untouched for years. Undisturbed conditions are what both pests need.

The Roof Is Worth Sorting Even If You Do Nothing Else

Where the survey finds old nesting material, dealing with it does two things beyond the pest problem: it removes a reservoir that would otherwise feed the next population, and it usually means closing an opening at the roofline that let the bird in - which is worth having closed anyway.

That last part may be proofing work at £180, up to 1 hour, or it may be a roofing repair, depending on what is failing. We will tell you which rather than quoting for something we should not be doing.

What Does Not Work

• Treating the floor and stopping there, where a reservoir exists. The whole of this article, really.
• Replacing the carpet without treating. A new wool carpet in an untreated room is fresh food.
• Moth balls. Aimed at a different pest in a different place.
• Clearing the loft yourself the day before. Distributes the problem through the house on the way down.

If the Damage Is to Clothing Rather Than Carpet

Common, and it changes what gets treated rather than whether.

Carpet beetle is entirely willing to work through stored wool clothing, and where the damage is in a wardrobe rather than on the floor the population is living in the storage. Treating the carpet in that room will not reach it.

1. Empty the wardrobe and the drawers completely. Everything out, so the carcass and the corners can be treated.
2. Hot wash what can be washed, at the highest temperature the fabric allows. Professional cleaning or a sustained period in a freezer for what cannot.
3. Check the back panel and the underside of drawers, and the floor of the wardrobe - that is where the shed skins collect.
4. Bag and dispose of badly damaged items rather than putting them somewhere else in the house.
5. Do not repack until the treatment period is over, and put clean items back rather than the ones that came out.

If there is damage in a wardrobe and on the floor, tell us both - it does not usually change the room count and it changes what gets done within the room.
