Could the holes in your couch and clothes be caused by a carpet beetle?

We sit down with expert Daniel Neves of Inoculand Pest Control Services to find the culprit responsible for the damage in your home and what you can do about it.

Q: What are carpet beetles?

A: They are tiny insects and a common household pest in the UK. They measure between 2 and 4 mm and are often likened to small caterpillars. The distinctive orange, yellow, white and black markings on their backs easily distinguish them from other beetles.

Q: How do carpet beetles get into your home?

A: They can enter through an open window or door, or enter the house through other routes. For example, a plant from outside, second-hand furniture, stuffed animals or already contaminated fabrics.

Q: Are carpet beetles dangerous?

A: They can cause skin, eye and respiratory irritation, but otherwise pose little threat to your health. They can, however, wreak havoc on your home and possessions.

Q: How do you detect a carpet beetle infestation?

A: The four most common signs of a carpet beetle problem are:

  • Holes in your clothes, furniture and carpets.
  • Damage to book covers and photos.
  • Spot dead skin in the corners of your home, around baseboards, windows and light fixtures.
  • Find an adult carpet beetle in dry foods such as pasta, cookies, and flour.

Q: How quickly does an infestation spread?

A: A carpet beetle can lay over 100 eggs, which means an infestation can quickly become a big problem. Since adults can fly, it is easy for them to reach other areas of your home and even your car.

Q: What can you do to prevent an infestation?

A: There are several things you can do to prevent a carpet beetle problem:

  • Vacuum your carpets, rugs and under furniture regularly.
  • Hot wash your bath mats, curtains, cushion covers and throws every few months.
  • Place all dry foods in closed containers or airtight packaging.
  • Wipe off the leaves of all outdoor plants before bringing them indoors.
  • Clean vintage furniture and antiques before entering the house.
  • Seal the cracks around your windows and doors and install screens.

Q: How do you get rid of a carpet beetle infestation?

A: You can attempt to eliminate an infestation without using pesticides. You should immediately vacuum the infected area, discard the bag, and steam clean all fabrics and areas of the room. However, since the eggs are difficult to spot and can take up to a month to hatch, it can be difficult to eliminate an infestation yourself. In most cases, it is best to contact a pest control expert.

We will assess the extent of the problem and recommend the most effective treatment to eliminate them. To completely eliminate carpet beetles, it is essential to break their life cycle by killing both the adults and the eggs.

We use a fogging machine to generate an insecticidal mist that reaches every nook and crevice where the beetles can hide. This instantly kills adults and larvae and remains active long after application to kill remaining eggs as they hatch. Two weeks later, we’ll do a follow-up procedure to make sure all the carpet beetles are gone.

Q: How long does the treatment take and is it safe?

A: Each treatment takes less than a few hours. We only use HSE approved pesticides which are completely safe and will allow you to go home two hours after the treatment is finished.

Q: Will I need to prepare my home for pest control?

A: It is best to tidy up your home before we arrive, however, we advise you not to vacuum between visits as this can remove some of the pesticides and make the treatment less effective.

Q: How much does carpet beetle treatment cost?

A: Before arriving at the property, we can recommend the best treatment and provide you with a quote to help you decide what is best for you.
