A carpet beetle is usually a pest you have to worry about outside the home, but on occasion, an inside infestation can occur. They like to lay their eggs in carpets and other fabrics.
Once you have larvae in the home they can be quite damaging and it is best to get rid of them.
The carpet beetle larvae will create holes in the fabric and will invade any animal product, like leather or food.
The first sign that you may have a problem is that the adults will try to get back outside once they lay their eggs, so you will often see them at windows and other areas that access the outside. At that point, you need to find where they are laying their eggs and how the larvae are feeding to get rid of them.
Once you find these areas you should:
- Vacuum frequently (be sure to do all areas with carpet and fabrics, including furniture and drapes)
- Eliminate any piles of clothes or other materials that larvae could feed on
- Remove bee or birds nest around your home (these are hot spots for laying eggs)
- Use an insect spray and spray around the floorboards and furniture
When you do these things you will be removing new eggs, removing larvae, preventing the carpet beetles from having anywhere to lay their eggs and removing food sources. At this point, there will be no reason for them to want to be inside.
Fortunately, these are not too difficult to control. You will have a hard time keeping them out once they start coming in, but getting rid of them is not too hard.
As long as you do a good cleaning of carpets, furniture, rugs, and drapes then you should be able to get rid of them. If you seem to have a persistent issue with carpet beetles, just use an insect spray and this should do the trick.
Consider washing your fabrics. Use hot water to clean them. Stuff, such as towels and linens should be washed in a washing machine containing hot water.
For very bad infestation, consider steam cleaning all your carpets as well as upholstered furniture. You may know that carpet beetles tend to be resilient. So, using hot water is better than using cold water.
Lastly, if you do find the specific area where the carpet beetles are getting in then you can simply close it up so they can no longer get in.
Be aware, though, that most will enter from the attic area or in some area where they can easily get inside.
You may not find the actual entrance, but as mentioned, if you do everything to get rid of them then you will be eliminating the perfect environment for them to live and they will not be interested anymore in coming inside.
