Bug retardant insulation, usually made of natural cellulose insulation, is a loose fill material applied in attics. To use this type of insulation in the attic. you will need baffles installed to help keep the material away from soffit vents. The baffles will also prevent wind from blowing up into the soffit vents and moving the insulation around in the attic. Make sure you don’t cover recessed light fixtures unless the fixtures are certified to accept insulation.
