Ants are smart, and if you have food lying around, chances are they will find it and invite their buddies over for a feast. If your dog or cat leaves food in the bowl, deter ants with a little petroleum jelly.

You can rub a little jelly around your door jambs or the cracks of your windows, but if ants still find a way to sneak in and take over your dog or cat food bowl, try rubbing jelly directly on the bowl itself. The trick comes via Good Housekeeping:
Flip the food bowl upside down and dab some of the petroleum jelly near the base to create a slippery barrier. Ants won't be able to climb over it to approach your pet's food, and since it's on the bottom of the bowl, your cat or dog won't eat it with their dinner.
I tried this with outdoor food bowls, too, and it worked well. It's an easy enough solution if you can't keep ants out of your home or apartment. For more tips, head to the full post below.
