Using the crack and crevice tip supplied, hard to treat cracks can be treated effectively for excellent roach control. It dries clear, but does have an initial odor. There are numerous types of monitors, but if you have children or pets or both I strongly recommend the D-sect. It is a plastic covering for the monitor board and can be mounted most anywhere. It will prevent dust, food particles etc. out of your glue board and keep the monitor where you want it.
Inserts are cheap, and trays can be installed for baits.
It is waterproof, and can be used anywhere it is labeled for such as kitchens, attics, etc. It can be used directly from the bottle, but I recommend buying a hand duster for a more even application. Delta Dust is safe, a .001 percent active ingredient but lethal to a wide variety of insects and spiders. Insecticide dust formulations generally last longer than liquids, inexpensive, dermally toxic as well as a contact poison.
