Once you have dealt with a pantry moth infestation, you know how important it is to keep these pests from returning. There are several steps you can take to avoid having this problem again.
1. First, check the places you frequently buy grains and organic products: Grocery stores, pet stores, nursery and home depot type stores... if you SEE pantry moths flying around, there's a good chance that they, too, have pantry moths and that whatever you buy there might be infested or have eggs waiting to hatch. If you see pantry moths flying around, you might want to shop someplace else for awhile.
2. Next, you can avoid a pantry moth problem by freezing andy new dried foods that you bring into the house before putting them in your pantry. In my experience, most foods can be safely frozen with no ill-effects when you use them later. I was surprised to find that I could freeze flour, rice, cereal, dogfood, and even powdered sugar and then safely use them later when they thawed out. Freezing these items will kill any miscroscopic eggs or larvae in the food and make sure that they don't get a chance to hatch into adult pantry moths. Even though it might seem kind of gross, pantry moth remains will NOT hurt you and cause no harm if they were in your grains. Either way, it's a good way to give yourself peace of mind about not having another moth problem on your hands. All of my recently purchased grains and baking suppplies spend a week in my freezer before hitting my pantry shelves!
3. Change your trash frequently to keep bugs out and don't leave old, outdated items (like spices) in your cupboards. If you haven't used something in, say, 6 months, chances are you aren't going to need it and is has probably lost it's freshness anyways. Those old boxes of cakemix, bags of seeds and nuts, and ancient spices are not worth the risk of pantry moth infestation.
4. Keep all your grains and high-risk items in glass sealed containers. Many pantry moths can make their way into plastic, cardboard, and baggies. Suction-sealed galss containers and jars are best because they don't have the screw-tops that moths can wiggle their way up, through, and INTO your food.
5. Finally, keep your kitchen as clean as possible. Mostly, I am referring to food particles that could be left around for the moths to feed and reproduce on. Simple things like a little bit of spilled flour near the container or on the lid can be a perfect meal for pantry moths. Make sure your family is careful during mealsand snacking to clean up after themselves and not leave crumbs of food around.
If you follow these tips, you can help avoid pantry moths returning to your home. Also, spraying Aunt Norma's Pantry Moth Spray on the outside of closed cupboard doors can send a "not-welcome" message to the moths in case they do find their way in (or you have some left over from a recent infestation). They ned to eat to survive and reproduce, so keeping them away from your food will make your home a less than ideal environment for them.
