Indian Meal Moths

Lindsay and I have for several weeks noticed little gnat/fly/mothy creatures around the apartment, particularly in our pantry. At first it was an annoyance, but as we started taking notice, it became especially annoying for 2 people who are relatively (ok, ok very) clean and tidy. Bugs in our apartment?? Seriously, what kind of crap is that?? An exterminator came for the whole building, and we thought it would be fine. Nope, still there. So we were informed they live in grains and oats and stuff and we should get rid of those types of food, as they can come in from food purchased outside, and then lay eggs places. So we got rid of those things. But they're still there. This we discovered when Linds wanted to eat oatmeal this morning and discovered tiny little maggot-like larvae in said oatmeal container. Mmmm what a great way to start a Monday. So, we are informed by our building owner that they are in fact Indian Meal Moths and in order to get rid of them we have to dispose of all food in which they could possibly lay their eggs. First of all, why/how did he know that they were indian meal moths? And really, who has them?? Fruit flies, cockroaches, mice... all "normal" apartment critters... but INDIAN MEAL MOTHS??? Seriously. Tonight begins the purging of all possible sites of IMM breeding. Updates on the status of the IMM situation at a later date.
