My wife and I own a 3 year old home in the Northwest. This winter, larva/pupae were crawling on the walls of multiple rooms. We killed all that we encountered, and determined that we havevaried carpet bettles.
We vacuum the house daily (via a new roomba 960 and regular vacuum for the stars). We washed, dried all clothing and wrapped it in plastic (from the dry cleaners). We went through every food item and threw out anything that looked like it could possibly be infested. We found 2 "boxed goods" with a single carpet beetle in each. We basically threw almost everything out.
Since that time our clothes, and I mean all of them, have either been in plastic bins or plastic. We continue to freeze and then ziplock or glass jar food products that we purchase. As it sounds, this has been a complete and total pain in the ass.
Today we had our first warm sunny day of spring, and found the adult bastards (they are tiny) all over...I bet we killed 10 of them. During the last two months, we killed 2-4 adults per week. Both my wife and I look over every room in the house almost daily; they are easy to spot as our house is a light yellow color and about 1600 sq feet.
Anyone ever deal with this? It has been such a pain in the ass. I don't know that it is worth calling an exterminator. I have read what I could on the internet. Aside from initially going through everything (clothing and food) and continuing to keep stuff packaged up, vacuuming daily and killing everything we see, is there anything else anyone knows of that we can do? Tired of dealing with it....it is a bit draining at this point to wake up at 6am for work and have to untie a plastic bag to get a shirt and pair of pants out.
