As a Master Beekeeper, I always look for potential problems during routine hive inspections. Seeing a line of ants crawling up the side of the hive means it is past time to take action against this honey bee pest.

Effective Strategies

There are many different ways to keep ants from destroying your hives. But it is important to understand that dealing with ant infestations requires some trial and error. What works in one region may not work for your hives.

3 Approaches to Ant Control

  • prevention
  • repellents
  • physical barriers
  • mound control


Avoiding a problem is often easier than fixing one. There are things you can do to make your hive area less attractive to ant colonies. And honestly, if you are feeding sugar water to your bees, don’t spill it.

Keep Your Bee Yard Clean

When you are working your colonies, avoid throwing down pieces of honey comb, burr comb and other types of hive debris. This attracts many types of predators and pests that are looking for a free meal.

Trim grass and tall weeds in the bee yard – put something under the beehives or use a close cut ground cover. This will aid in the visibility of ant mounds.

Monitor Conditions Near the Hive

Stroll through the apiary on a warm afternoon and look for external problems. A small ant trail is no cause for alarm, but it may signal the need to take a closer look. When you see mounds, destroy them.

Natural Repellents

Some beekeepers have success with various types of natural repellents. Essential oils such as peppermint, cinnamon, and citronella can be strategically applied around the hive (but not on the hive) to create a deterrent barrier against invading ants.

Herbal plants such as mint and basil may deter ants due to their aromatic properties. If you live in an area with Small Hive Beetles, avoid planting anything too close to the hive. 

The ground moisture will aid beetle production and the tall plants will serve as a bridge for crawling insects entering the hive.

Local beekeepers often use ground cinnamon (spread in a ring on the ground around a hive.) My ants seem to like it-but it works for some folks.

Another substance – DE (diatomaceous earth) is a fine powder derived from fossilized algae. It is really more of a physical barrier than a repellent but it is natural.

Do not get it on the landing board (entrance) of your hive and take care not to breath in the fine dust. Wood ash is sometimes used in the same manner.

Physical Barriers

One of the easiest things you can do to help keep ants out of a beehive is to use a hive stand.  Yes, ants can still invade because they can crawl almost anywhere.

But, if the legs of your hive stand are small enough, you can create an “ant proof hive stand” by putting the legs in a can of vegetable oil or soapy water.

Another way to keep ants out of the beehive is by using something sticky on the legs of the stand. Vaseline, grease or a product called tanglefoot will keep those legs from becoming an ant highway.

Mound Control

If the ants have already set up housekeeping near your beehives, you many need to do some mound control.

Because ants and bees are closely related, finding a pesticide that will not harm the bees is almost impossible.

Granular Bee Friendly Ant Killer

Be very cautious with any spray or powdery product that may drift onto the hive or blooming plants-use a granular ant killer to destroy mounds near the hives.

This is not a completely safe alternative but using a granular pesticide (instead of powder) will reduce risk to bees.

Read the label carefully for any cautions and spread it gently to avoid pesticide particles landing on the hive entrance.

Expert Tip

After many years of beekeeping, I know that prevention is the key to avoiding problems with ants in your hives. Practice good bee yard hygiene (no spills or discarded sweet comb) and create a barrier around your hives to discourage foraging ants.

If you have an active infestation, the preventive measures may solve the problem. However, if the ants have moved in and are living in your hive – you may have to move it to a new location to get them out.
