I’m a frequent buyer of your products and have a question about a product of yours, perethrin. I was curious if it stains fabric. The type of pest I see is the varied carpet beetle. I’m not seeing a lot but like 5 at a time and I’m looking at your pamphlet for this pest. It suggests I apply some perethrin, but it doesn’t state if it stains fabric (i.e. sectional couch).
Perethrin, also known as permethrin, can be applied inside to carpeting and fabric and generally will not stain. We always suggest applying it to a “test” area first to see. This area should be a small section, preferably some area out of sight, like the bottom side of a cushion. Let it dry for an hour or two and you should be able to tell. In most cases, the area might appear “wet” when applied but once dry, won’t be noticeable.
Although you don’t feel like you’re seeing a lot, there probably are many others not being seen and most importantly, there is definitely the chance of a lot of eggs being laid. These eggs could turn into a major infestation if left untreated as explained in our Carpet Beetle Control article. Tackling this problem now will prove a lot more efficient and the permethrin would be a good choice for the treatment.
