Last week, my partner found a small beetle lurking on the windowsill of our small, two-bedroom apartment. We're almost certain it was a varied carpet beetle (it looked just like this
). Since then, we've been finding them fairly frequently—once a day, on average, and my partner found one larva the other night. We haven't found any noticeable damage, but as my partner is a knitter, she's particularly concerned.
Since finding the first couple, we did a massive spring cleaning of our apartment, vacuuming everywhere, including behind furniture, in closets, and everywhere we could possibly reach. We're still finding the bugs though, and can't figure out where they are coming from or going to—they've shown up in every room in our home, but we haven't seen any visible damage to any clothes, nor found them in any foodstuffs.
So, the obvious question: what can we do? We're going to clean and vacuum-seal our natural fibre clothes, but we don't want this infestation to get worse, and we don't want little bugs in our apartment. Is there a readily available and safe product we can use that will get rid of them, even if we can't find the "nest"? Do we have to get an exterminator? How much would that cost for a 2-bedroom apartment? (We're both poor graduate students.) Would it be our responsibility to pay, or the landlord's?
We live in Southern Ontario, and are desperate for help!
