With the weather warming up, you can expect to start seeing pantry moths again. Often times, the eggs can go into a holding period, so to speak, from last season and not hatch again until the weather starts to warm up. Like many animals and insects, pantry moths can inherently know when spring is coming, and when it's time to start reproducing. If you have spent the winter months moth-free, you may think that you are done with the pests forever, only to be shocked and horrified when you start seeing these pesky moths come spring.
The best way to avoid a full-blown infestation is to get rid of them before they take hold again. As soon as you see a moth, assume that this moth has hatched from inside the home from a leftover egg. You should immediately check your food and make sure that it is stored in airtight glass or suction sealed containers. I also recommend to put pantry items susceptible to pantry moth infestation (rice, flour, grains) in the freezer for awhile. The easiest way to get a jump on a pantry moth infestation is to clean out the cupboard with Aunt Norma's Pantry Moth Spray and put out a Pantry Moth Trap. Aunt Norma's system works by interrupting the life cycle of the moth, preventing a full-blown infestation.
