To control the moths, you can purchase pesticide-free “moth traps” which have a pheromone that lures the moths in. But because each moth can lay 400 eggs into birdseed or our own cereals, pasta, and other food made from grain, it’s important to keep both our birdseed and our own food carefully sealed.
In winter in cold climates, keeping birdseed of all kinds stored in an unheated garage or back porch will keep any larvae from being active, and cold enough temperatures will kill most of them. But even in the garage, it’s important to keep birdseed well sealed in chew-proof containers to prevent other pests from gaining access. Metal garbage cans with tight covers can be ideal for keeping squirrels, raccoons, mice, rats, and other mammals out.
In warm climates or where you must store your seed indoors, make sure to keep it well sealed. Even if you don’t feed birds, noticing small moths is a good idea—they sometimes get into human food supplies before they even reach our homes. If you do notice small gray moths flying about, seal all your food, your pets’ food, and any birdseed in airtight containers and set out a moth trap or two.
