What works best in getting rid of roaches?
The best method I found, and the one we use for the storage rooms at the local food bank is a simple little ultrasonic screamer device … most bugs, roaches included, just do not like the constant noise in the ultrasonic range that these things produce … they may hunker down for a little while, but they will all just leave in search of a more peacefully quiet location within a day or two … the power cost to run such a device is far less than the cost of continuously replacing poisons … and these devices are harmless to humans and we can not even hear the ultrasonic noise being blasted out.
