Termites eat dead wood and often they can find it on live trees. They can eat the bark or sometimes a tree limb will die and they can eat that.

 

Here is Arizona they consume dead grass, dead cactus and anything that contains cellulose.

 

Don’t panic, they are just doing what they are supposed to do – consume dead wood.

 

I often recommend just keeping any eye out for the termites, it isn’t always necessary to treat especially since they are just eating the dead wood.
