How to Keep Ants Off Hummingbird Feeders

Repelling Ants

Invest in an ant moat. An ant moat is a small cup. You place it between the feeder and the tree branch the feeder hangs from. Ants are unable to go through the water and get into the feeder. You can buy a moat and attach it to your feeder, following the instructions. If you don't already have a hummingbird feed, buy one with an ant moat already installed.

Add oily substances outside the feeder. Take a sticky substance, such as vaseline, and spread it on the outside of the feeder. Ants will be unable to crawl through this substance to get to the nectar.

Hang the feeder on fishing line. Fishing line tends to be very slippery. Ants have a difficult time moving across fishing wire. Hanging the hummingbird feeder from fishing line will make it harder for ants to get to the feeder.

Add bay leaves or mint leaves. Ants do not like the smell of these leaves. They normally tend to stay away from these leaves.

Adjusting the Feeder

Check for leaks. Check the feeder carefully on all sides. See if you notice any cracks that are causing leaks. Leaks are one of the easiest ways to attract ants. If you notice any leaks, get a replacement feeder.

Clean the feeder. Each time you add new feed to the hummingbird feeder, wipe down the exterior to remove any built up sugar residue. Ants are attracted to sugar residue, so cleaning the feeder can keep them away. Wipe the feeder down using very hot water, but make sure the water is not hot enough to burn your hands. Keep wiping the feeder until all the sugar residue is gone.

Adjust the food you're using. Homemade hummingbird nectar is generally one parts sugar to four parts water. However, to deter ants, try using slightly less than one part sugar. Hummingbirds will still feed on the nectar but less sugar will draw in less ants.

Changing the Feeder Location

Move the feeder frequently. Ants build habitats around food sources. Periodically moving the feeder will keep a colony of ants from settling near the feeder. Every couple of weeks, move the feeder to a different location in your yard.

Hang the feeder in the shade. Ants may be less likely to invade a feeder found in a shaded area. However, a completely shaded area will fail to attract hummingbirds. Look for an area that's partially shaded so hummingbirds can still access the feeder.

Place the feeder over water. If you have a fountain or other body of water in your yard, hang the feeder over that. This will prevent ants from crawling towards the feeder as ants will stay out of water.
