Dominion 2L Termiticide can be sprayed around and on the tree up to breast height. The holes you do see are best to be sprayed and completely covered.
Dominion 2L Termiticide/Insecticide can be used in the soil and/or around the foundation. Where you are using the product will depend on what you are treating for. For termites, you will dig a trench around the structure and apply directly to the soil. For pests, such as ants, you will apply topically one foot up and one foot out.
Dominion 2L Termiticide Concentrate cannot be used inside so is not labeled for bedbugs nor is it labeled for common crickets. It can be used as a perimeter spray outside around the foundation for ants and roaches or as a systemic soil drench on plants/trees for aphids. You can review the product label for the list of insects it controls and application instructions.
