Hi all,
Do you have trouble with gnats and smelly trash cans? I have been saving my potato chip bags and other plastic type freezer bags, (like french fry and frozen meat patties) to put my veggie waste into before throwing it in the trash can. It doesn’t completely get rid of all the problems, but the odor is less and the flying pests seem to be kept at bay. I keep the bags rolled up and stashed in an old coffee-type can. If you put the plastic lid on the bottom, it acts as a scratch barrier. Hope this helps.
Enjoy!
