I came upon your site by accident trying to identify a species of moth that’s been living with me. I just moved into a new apartment a few months ago and noticed that there were several moths in the apartment. I have no picture, but they are small, maybe 1/4 inch long, and very thin – they look a lot like a tiny segment of a stick. The head end tapers down slightly narrower than the wingtips. They are a mottled dark brown colour. They tend to sit on walls for long periods of time very still and only fly away when approached. Their style of flying is erratic and fluttery. I found a dead one in my pancake mix and the mix itself had a sour smell to it. I also found a small larva about the same size as the moth, white with an orange head, hiding under my teapot. I’m not sure if this was a larva of the moth or something else, though. These moths tend to hang out in the kitchen, so I have a sneaking suspicion that they may be after food. In some corners under or inside the cupboards I have found dead (or possibly the molted skins of) moths attached to the corner within a thin layer of silk. Any ideas on what these are, and if they are bad to have in the house?
You have pantry moths which will infest all types of grain products in the pantry, hence the appearance in the pancake mix. The larvae do the damage by devouring the foods. Mature moths will lay new eggs and the infestation perpetuates. Clean out the pantry and store drygoods that you
are not going to use immediately in a tightly sealed container (though this does not prevent eggs that have already been laid from developing) and better yet, refrigerate or freeze flour products. Do not stockpile drygoods when you have a potential problem in the pantry.
