How Do Ants Kill Trees?

Depending on the species, ants can be good or bad for trees. Some species feed on aphids and honeydew, which may destroy tree leaves. Other species live in tree trunks. But some species, such as red fire ants, can be destructive to lemon trees. They chew bark all the way around the trunk, which can kill the tree.

Some ants will also tunnel into a tree. This can be especially damaging to young trees. It can also expose the roots, drying them out.

Fortunately, there are ways to deal with ants. The most common is to spray ant powder around the base of the tree. You can also use baits to catch them. This may be illegal in your county.

There are also horticultural insecticides that can be used to kill sap-feeding insects. If you don’t have the equipment to do this, a qualified arborist can help you. They can also determine if the tree will survive or if it will become a hazard.

If you find ants on your tree, you may want to try peppermint oil. A mixture of peppermint oil and water can be sprayed on the tree. The solution should be sprayed several times a week.

If you have a larger tree, you may need a systemic insecticide. Some pesticides can be harmful to bees. However, you may want to contact your local environmental department before using any pesticide.

Carpenter ants can be especially destructive to trees. They dig tunnels through wood, forming a nest. They are also attracted to moist areas.
