Don't Worry about Ants!
If you see columns of ants marching up and down the trunks of mesquite or other trees, don't worry. This is a natural occurrence. According to my friend the entomologist, ants do not harm trees; they are collecting food to take back to the colony in the form of insects or sap. When trees are in flower, ants assist with pollination.
Bark Beetles and Firewood
If you live in the Southwest, you've likely heard how the combo of extended drought and bark beetles adds up to devastated forests susceptible to wildfire. Firewood and Bark Beetles in the Southwest, an updated downloadable publication from University of Arizona Cooperative Extension, helps you identify infested trees as well as learn how to handle and store firewood appropriately to reduce the risk of spreading beetles. The publication also warns against treating firewood with insecticides.
