We all get them at one time of another-pantry pests-Indian meal moths,
grain/flour beetles and many other tiny bugs that infiltrate our
pantries, cupboards and storage areas.
Pantry moths most likely got into your house with some type
of purchased food. They are found in flour, dog food, biscuits,
pasta, cereal, dried beans, bread, spices, cookies and very often
in bird seed, because it's not regulated the same as food. Store
birdseed, dog food and that type of thing in a shed or garage if
possible. Many times the eggs hatch after you bring these items
home, and before you realize it, you have a problem.
The larva are very small, not much bigger than a piece of rice.
The moths are small too, but easier to see and identify.
If you see small moths flying around, especially near or in
your cupboards or pantry, then you need to start searching!
Look everywhere--grains, nuts, spices, dried peppers, and
even things you wouldn't consider suspect. If you find it,
you'll know. Most likely you'll see webbing, or larva. If you
throw out that item--outside in the trash-and use a few of the
following tips you may get on top of it quickly. A note on
the Indian meal moth---they may not be limited to kitchen
areas if you've had them for awhile. Check all dark places
for the webbing.
Traps: Buy non-toxic moth traps that use pheromones to lure
the moths. One trap per room is all you need-more than that
will confuse the moths and it won't be effective. Usually this
method will work if combined with cleaning and finding the
source of the moths.
Alternative trap: Mix boric acid with cornmeal-at a 1 to 3 ratio.
Place mixture in jar lids or washed tuna cans in pantries and
cupboards. Keep this away from kids and pets.
Clean: Remove everything from cupboards or pantries. Vacuum
out every nook and cranny-top and bottom! Take the vacuum
outside, remove the bag, and place it in a garbage bag. Tie and
place in the trash can---don't keep it near the door. Afterwards,
wipe down the cabinets with a vinegar solution. Use a sponge
or a rag, but make sure it's really saturated. You want to get in
all the crooks and crannies.
Essential oils: consider washing everything down once a month
or so, and putting cotton balls with 10 to 15 drops of Eucalyptus
essential oil in the corners of the cupboards, pantry and closets.
Extreme cases: IF your moth infestation is really bad, you will
need to throw out all items made of grain and the other things
we've talked about today. Get rid of it all and clean, clean, clean.
I came close to having to do this, but managed to limit it to one
cupboard that I knew was the problem. I also had them in the
basement and discovered it was birdseed I was storing. I now
store that in the garage in a large can with a tight lid.
PREVENTION
What can you do to prevent pantry moths? Sometimes nothing,
but you can follow these tips to minimize the chance.
-When you purchase items that I've mentioned today put them
in the freezer for 3 days to kill anything that may have come
home with you.
-Store your rice, flour and cornmeal in the refrigerator or freezer.
I do this mostly when I buy a lot of extra that doesn't get used right
away. Don't mix old and new grains or flour. Use up the old, then
wash and dry the container before storing the new batch.
-Place bay leaves in your grains--but this is only prevention. It won't
kill the eggs or larva, but it will usually keep them away. Use 2-3
leaves in each container.
-Watch your rodent population. The pantry pests can breed in their
nests AND in the bate traps for rodents.
