We have a roach problem outside near a large pine tree on the side of our house(removing many barrels of pine needles helped) and in our garage - the pine tree is near it (we haven't found them in the house yet). Will the bait and the IGR stations work if placed outside in the sun and rain? Where should they be placed? We do have a pest company spray the exterior monthly with Tengard.
For outdoor control you can use Demon WP but the IGR that comes with the kit is not effective outdoors. Instead you should consider using Demon WP mixed with Nyguard IGR and apply to the infested areas.
