Hubs and I are waging a war against cupboard moths. We thought we'd eradicated them by throwing out almost every food item in our kitchen and sanitizing our cupboards. We bought hermetically sealed food containers and vowed to use only those from now on. And yet, they have managed to return. I bought a brand new bag of rice, put it in a hermetically sealed jar, closed the lid, and two days later it's crawling with moth larvae. Apparently we are going to have to throw out the remaining food (some web sites say the larvae get into spices, too), remove the ugly light covers and clean up in that godforsaken area and bleach the whole kitchen.
Meanwhile we are conducting an experiment with the larvae in the rice, waiting to see if they will spin cocoons and become moths. Sort of disgusting. Perhaps I should document with photos!
