Ant infestation in oak trees

We have several large oak trees in our yard that are severely infested with small black ants. The ants apparently live/nest in the trees but have recently started moving around our yard a lot and are everywhere. Now they are even in our house, specifically in our attic. No other products have been successful in exterminating them so my mom suggested we use Sevin products. The product states it is specifically for outdoor use so is it safe to spray in the attic? We also have a large population of squirrels that we feed so which of your products would be safe to use that would not be harmful to our squirrel population?


Sevin Concentrate is labeled to be used outdoors only. For ants indoors, we would recommend using something like Phantom Aerosol. This can be sprayed around the baseboards, cracks and crevices, void treatment where pests harbor, nest, trail, run, and/or breed or hide. Treat into voids or to surfaces beneath cabinets, furniture, spaces between equipment, expansion joints, surfaces behind sinks, floor drains (to sewers), lockers, and water pipes.
