Why Does Cockroach Spray Work?

A cockroach spray is a chemical product that is used to kill cockroaches. These pesticides have two main components: a chemical that can kill on contact with roaches and a residual spray that works to poison them over time. The chemical will last for a period of time after it is sprayed, varying from a few hours to as long as four weeks. Regardless of the type of spray you choose, there are certain tips to use it effectively.

A cockroach spray contains pyrethroids, a chemical compound that interferes with the neurons in a cockroach’s body. It works by interfering with the activity of proteins that carry sodium and potassium across the neuron membrane. This interferes with the nerve signals, causing the cockroach to die or be incapacitated. This chemical compound is generally harmless to humans, but it can be toxic to aquatic organisms and sensitive individuals.

Cockroach sprays can be highly effective. Some products contain essential oils that have been proven to be effective against roaches. Some of these essential oils have repellent qualities and others kill roaches on contact. To make them effective, they must be delivered at a concentration high enough to reach the areas where roaches travel.

Cockroaches are often attracted to dark, moist areas. They congregate in floor drains, sump pumps, laundry areas, and boiler rooms. They can also be found outdoors in trash containers and yards.
