Do Cockroach Sprays Work?
WouterOne of the first questions you may have is, do cockroach sprays work? The answer is yes. These pest control products are designed to repel cockroaches and kill them on contact. However, the sprays may not be effective on the first visit. You must remember to shake the can thoroughly before you apply it, and leave at least 18 inches of space between the can and the roaches’ entry point. Then, apply liberally to affected surfaces. If possible, do not spray pet hair or furniture.
Cockroach sprays are available in both contact and residual formulations. Residual sprays are more effective at killing roaches that evade view. Combined with insect growth regulator sprays, residual sprays will eliminate roach infestations over time. Cockroaches pose health risks and should be killed as quickly as possible.
Contact killers are widely available and cheap. They kill roaches on contact and can kill many in a single treatment. Contact killers work best when used in combination with residual or IGR sprays. The problem with contact killers is that they do not target the heart of the colony.
Whether or not you choose to use a cockroach spray is up to you, but if you’re worried about the safety of your family or pets, you should always read the labels. Make sure the product you choose is safe for pets and children and always clean up any residuals after using it.
