Using the RoachBane Cockroach Gel is very easy and can be used both in/outdoors.
Simply put a few dabs of the gel bait in areas where cockroaches have been seen.
Common areas are plumbing pipes, near holes to wall voids, under sinks, in closets, cabinets and behind appliances such as the fridge and microwave.
The gel should be applied in small dots, about the size of a pea, spaced 12 to 18 inches apart.
