The pesticides used on avocado trees are not effective against all of them. Some are beneficial to the avocado tree, but they aren’t safe for the trees themselves.

Observation is also important. Caterpillars can kill your avocado crop in a matter of months if they are not controlled. Fortunately, there is an easy way to stop them.
