Ants in hives

Elevating hives on stands and applying grease to the stand legs is a widely used and effective method for preventing ants from accessing beehives. The elevation makes it more difficult for ants to climb, and the grease creates a sticky barrier they cannot cross. Food-grade grease or specialized ant grease products are applied to the legs of hive stands, typically in a band a few inches wide. The grease barrier needs to be reapplied periodically, especially after rain or when it becomes contaminated with debris or insects. This method is inexpensive, easy to implement, and provides reliable ant control for elevated hives.

Using cinnamon as an ant repellent is a natural and less toxic approach to deterring ants from beehives. Cinnamon powder or cinnamon essential oil can be sprinkled around the hive base and entrance areas. Cinnamon is believed to disrupt ant trails and deter them due to its strong scent and irritant properties. While cinnamon is generally safe for bees, direct application inside the hive should be avoided. Cinnamon's effectiveness may be limited to mild ant infestations and needs to be reapplied regularly, especially after rain or watering. It is a low-cost and readily available option for beekeepers seeking a natural ant deterrent.

Applying food-grade diatomaceous earth (DE) around the hive base is another natural method to control ants. DE is a fine powder made from fossilized diatoms that is abrasive to insects' exoskeletons, causing dehydration and death. Food-grade DE is safe for bees and the environment when used correctly. It should be sprinkled in a dry ring around the hive base, creating a barrier ants must cross. DE is most effective in dry conditions and needs to be reapplied after rain or watering. While DE can deter ants, it should be used cautiously and avoided from direct contact with bees inside the hive, as it can also be abrasive to them. It is a relatively inexpensive and effective option for ant control.
