When a single adult is found climbing up a wall in an office during the day and the office does not have a sink or other water source, than it is a good bet that the cockroach was recently introduced into the office from another infested site. This cockroach could have come out from under the wheel casters of a cleaning cart, crawled through plumbing lines from a neighbor or was flushed into the area because of the use of insecticide sprays at another location. The trap surface must be tacky enough to hold these light insects as they scamper onto the glue. In recent years there has been considerable improvement in the design and function of insect sticky traps. Set several sticky traps around at floor level and others near sources of moisture.
Temperature extremes are excellent tools for preventing normal life cycle activity.
Baits are very promising, in recent years the improvements in bait formulations has resulted in dramatically reduced cockroach populations. The toxicant may vary from bait to bait as well as the food-based attractants. Synthetic hormones in baits show value in locations where bait stations cannot be used due to extreme conditions of moisture. These chemicals interrupt the molting process and prevent cockroaches from reaching adulthood. Over time, resistance may develop to either the bait attractant or to the toxicant but today, baits are producing remarkable results.
