An interesting question popped into my inbox this weekend, about prevention from insect infestations, and use of pesticides.
Dear Don't Move Firewood,
I lost several ash trees to pests this last couple seasons here in n.w. Ohio. I am concerned about a large maple tree. Nothing visible yet but as a precaution I wonder if a treatment of Lambda-cyhalothrin would be in order. It is a product that has worked well on the beetle (lady bug). Your thoughts would be appreciated.
