Biological pest control


Mechanical pest control


Electronic pest control


Cockroaches respond to electronic pest control devices by moving about a bit more than usual, but don't appear eager to escape from the sound waves. This includes devices that emit a uniform frequency as well as those that emit changing frequencies of ultrasound. Researchers were able to use the increased cockroach activity to good effect by increasing the rate at which they caught the roaches in sticky traps.
