Why there is no one timescale
A carpet beetle can spend many months, sometimes a couple of years, as a larva before it becomes an adult. At any moment, a house may contain eggs, larvae of different sizes, pupae and adults, spread across carpets, drawers and floor voids. Timescales depend on the infestation and the property, so they vary from home to home. Two homes with the same number of rooms can take quite different amounts of time to settle.
What affects it
- How many rooms are involved and how long the problem has been building
- Whether there is a source in the loft, such as an old birds' nest
- Old floorboards with deep gaps full of fluff
- How much clutter and stored textile there is in the affected rooms, which can be a lot in the larger period homes of Dollis Hill
- How closely the aftercare advice is followed
A single room with a clear source, found early, is a very different job from a whole house where larvae have been feeding under the floorboards for a long time.
Before the visit
Clearing floors, emptying the bottom of wardrobes and sorting clothes into washed and bagged piles make the rooms easier to reach. The steps for clothing are in can carpet beetles damage clothes and furniture. You will be told anything specific to your home when you book. If birds have nested in the loft, it also helps to know whether the hatch can be reached.
After the visit
Follow the aftercare instructions you are given on the day, including when to vacuum and when rooms can be used normally. Keep treated rooms as they were left until you have been told otherwise. Carry on washing and checking stored clothes, keep sealed items sealed, and return cleaned textiles to the room once they have been checked.
Seeing beetles in the weeks that follow
It is not unusual to find a few adults at windows after a visit, particularly in spring and early summer. Some will have been pupae or late-stage larvae at the time. The reasons they head for the glass are in why carpet beetles appear on windowsills. Vacuum them up and note the date and the room, so any pattern is easy to see.
Signs that things are improving
Over time you should notice fewer adults at the windows, no fresh skins in places you have cleaned, and no new holes in items you have been watching, using the patterns described in what damage carpet beetle larvae cause. Clean a patch thoroughly, note the date, and check it again later; that gives you a clear comparison rather than a vague impression.
When to get back in touch
If you keep finding live larvae or fresh cast skins in cleaned areas, or damage continues to spread, contact us with photos and the rooms involved. A source nobody knew about, such as a nest in the eaves, can be one reason. Dates from your notes show whether numbers are falling or holding steady.
Empty properties and changes of tenant
An empty house or flat is easier to work in, because floors and cupboards are clear. Landlords between tenancies in Kenton often choose that gap between tenants, so the next occupants start with clean carpets and cupboards. In an occupied home, the same preparation simply means clearing floors and cupboards in the rooms concerned.
Keeping them away afterwards
The routine that stops a new generation building up is in how to prevent carpet beetles returning.
