HI Bill, we can get insects from unfortunate dead animals but typically those would be beetles. since you have moths I wonder about Indian meal moths. as I mentioned in this thread they are common. the caterpillars will crawl up walls to find a place to pupate so they can become moths.The adult moths often fly around lights at night. it is a matter of figuring out what is infested and removing it, anything grain based from corn meal , flour to seed craft projects. vacuum cabinets, put grain based items in freezer or in glass or plastic containers. May want to check out some pix online to see if your moths match. good luck, sandy
