Entomology (Study of Bugs)/Little black bugs
There are little black bugs with white spots/patterns near my patio. In the bathroom, it seems like its coming from under the wall or something. They're about the size of the head of a pin. If one goes ignored, they turn into a white, yellowish larvae. When they're little and black, they move slowly and tend to stay in one spot. It seems like they like to hang on curtains, too.. What are they? How can I get rid of them?
With no image to look at, let alone a specimen, I can only guess at what you are talking about. You also have the life cycle backwards: Larvae turn into beetles, not the other way around.
Pretty sure you are talking about carpet beetles, so here is what I send everyone who has problems with them (and carpet beetles easily account for 60% of my questions):
Nine times out of ten, the insect that best fits such a generic description, and found indoors, is a carpet beetle in the family Dermestidae (genera Anthrenus
, and Attagenus
in particular). Carpet beetle adults are not really a problem, and in fact help pollinate some kinds of wildflowers. The larvae, on the other hand, are the insect equivalent of juvenile delinquents.
Carpet beetle larvae feed on all manner of dried animal products, including, but not limited to: pet food, taxidermy mounts, cured meats, insect collections (like mine, ARG!!), wool blankets and garments, silks, furs, even the accumulated shed hair of pets and people.
All you have to do is find the infested item(s) and discard it (them). To prevent future infestations, store all vulnerable foodstuffs in glass or metal containers with tight-fitting lids. Store woolens, furs, and silks in a container inside a cedar chest, as cedar has proven repellent qualities and is not carcinogenic, unlike moth crystals.
You can find many images of carpet beetles and their larvae online, including:
and also in my book, the "Kaufman Field Guide to Insects of North America." Feel free to get back to me if you can conclusively rule out carpet beetles (keeping in mind there are many species and much individual variation in color and pattern), and I'll try again. You can find more information on their control at any .edu website that addresses carpet beetles or "stored product pests" in general.
Here is more information:
Yours would be the "Varied Carpet Beetle," Anthrenus verbaci
, or a closely-related species.
One of these days I will put together my own fact sheet....Keeping your home clean of accumulating shed hair and skin flakes from people and pets always helps. Storing dry food (including dry pet food) in glass or metal containers with tight-fitting lids is essential. Put woolens and furs in a cedar chest.
Do NOT use chemical controls. Mothballs (naphthelene) are ineffective and moth crystals (paradicholorobenzene) are potentially carcinogenic.
Hope the above links and information help. Simply discard any infested items.
