Carpet moths / beetles

Although there are several types of carpet beetle the most common is the varied carpet beetle. 

It is the larval stage of the beetle's life cycle which causes the most damage to carpets by feeding on any natural fibres within the carpet.

The female beetle lay around 35-100 eggs in batches.

The beetles in their larvae stage are sometimes called 'woolly bears' due to bristles which can be seen around the edge of the body.

The larvae (woolly bears) emerge from the eggs and start feeding.

The larvae are repelled by the light and as a result cause deep burrowing into their food which is carpets.

  • Holes appearing in jumpers and similar clothing
  • Tufts of carpeting coming away when vacuum cleaning
  • Holes in carpets may be found when moving standing furniture as often the damage occurs underneath
  • However, if you see “woolly bears” crawling on walls, carpets and clothing then you know you have a problem
  • Once an appointment has been made you should ensure that the affected areas of carpets are thoroughly vacuumed and the vacuum bag is disposed of in an outside bin. Floors should be left as free as possible from loose objects eg toys, but rugs will need to be sprayed
  • The pest control officer will visit to assess the extent of the problem and identify that it is carpet beetles. We can only treat when we are satisfied that there is an infestation
  • Floor surfaces in the affected property will be sprayed with an insecticide. Occupants of the house will need to remain out of the house until the insecticide is dried; this is usually about 4 hours. The floors areas should not be vacuumed for a week to allow the residual insecticide to continue working; carpets should not be shampooed for 4 weeks after
  • The carpet moth./beetle treatment needs to be carried out when the occupiers are out and they should not return until the insecticide that has been sprayed and is completely dry, this is usually about 4 hours
  • The officer will leave you with details of the insecticide used and any safety precautions that should be followed
  • Carpet moths / beetles neither carry germs nor do they spread disease hence their presence does not constitute a risk to health
  • However, the activities of carpet moths/beetle will cause considerable damage
The best way to prevent a carpet moths/beetle problem is to:
  • Vacuum regularly (especially in areas under storage heaters or at the skirting junction)
  • Remove old bird nests, animal remains and dead insects are sometimes the cause of infestation
  • Destroy any pieces of old carpet or similar material in lofts or roof voids
