Last year, some of you may recall, I had
grain moths in my house. These creatures disgusted me no end, and I was filled with the fiery hatred of a thousand light bulbs for these pestilent little buggers.
Many of you gave me excellent advice, and I have had what looks like 100% success in stopping the infestation from recurring this year, in the hot weather. I know some of you have also suffered from this problem, so I thought I'd let you know what I did - and how I did it without using any poison or toxic stuff at all.
1.
Clean out the pantry. If you open a bag or box of rice, pasta, cereal, flour, or whatever and see a
single moth, throw it away. If you see any little pin holes in a plastic bag that's holding bulk goods, throw it away. Basically, anything that's already infested or shows the slightest sign of it: get rid of it.
Next, empty out and scrub down the places you keep food. I used baking soda and water.
2.
Change your storage habits. Get plastic or metal containers with airtight lids for keeping
any dry starchy goods outside of the refrigerator: pasta, rice, flour, oatmeal, cereal, bread crumbs, grains, legumes, and so on. Some people who commented on my original post have had problems with sugar, nuts, tea, cocoa and dried fruit, and other more sweet items, but I had no such problems - these particular guys were interested in grains and grains only, especially rice and whole flours. I also have had success keeping pasta in its bag, inside another strong Ziploc freezer bag.
3.
Kill any you bring home. You may not want to think about it, but when you buy in bulk from the bins in the store, there are sometimes going to be critters or eggs hiding in the food. When you bring home your grains, put them in the freezer or cold refrigerator overnight. The bugs can't survive the cold. Then put them in your containers for storage.
4.
Consolidate. If you can have all of your not-in-the-fridge food stored in one area of your kitchen, do so - it will limit the blast radius of any infestation.
5.
Discourage from the area. Cedar blocks thrown in dresser drawers help to keep moths away from your clothes; they do the same thing in food storage drawers, and don't affect the flavor of things at all. You can buy cedar blocks, drawer liners, or balls in many places, usually in the clothing storage area rather than food storage areas. Throw a couple in your cabinets and drawers and replenish them every 6 months or so with cedar spray.
6.
Pheromone traps. When the warmer weather came around again, you can bet that whatever moths were left from last year woke up or hatched or whatever those wretched bastards do, and I would see them in the house, one and two at a time. Whole Foods and health food stores carry pheromone traps for pantry pests, and they are brilliant. Basically, they're a triangle of light cardboard with sticky stuff on the inside surfaces, and a lure. The lure attracts the males, and they stick to the sticky stuff and die die die. I have mine on top of my fridge, which is a good height for them to fly into it; it currently has about 20 dead moths in it, most of which I never saw before they bit it. You may wind up with some females left over, but they can't make more little assholes without the menfolk.
7.
Integrated pest management. It's important that you do
all of these things together to destroy or prevent an infestation, or it won't work.
Thanks, everyone, for your fantastic advice.
