Dominion 2L is not labeled for indoor use as a pest control spray, meaning it is not permitted to apply out in the open indoors. We are not sure of the exact reasons why the manufacturer has placed this restriction on it. However, you can use Dominion 2L as a spot treatment indoors if you are treating for termites. You can spot treat inside for termites by treating inside wall voids or expansion joints since you are not spraying out in the open.
Dominion 2L would not work for elm bark beetles as it would not reach to the areas of the trees these beetles infest. Effective treatment involves killing the beetles before they bore into bark in fall and when they first emerge in spring so protecting healthy trees is best. Timing is critical to reach the pests before they're under the protective bark. You can use a product like Permethrin SFR for this. There are also articles linked below that can help

For treating Sea Grape Borers, unfortunately, there have not been any studies in recent years to show that any insecticide is effective on them. The best recommendation for control is pruning and destroying twigs infested with the borers as a method of reducing populations.
