SENTRY Natural Defense® works by attacking a neurotransmitter, called octopamine, which is only found in insects such as fleas, ticks and mosquitoes. Octopamine regulates insects’ heart rate and metabolism. The natural oils found in SENTRY Natural Defense® block octopamine — causing a complete breakdown of the central nervous system — killing insects quickly.


The neurotransmitter octopamine is not found in humans or other mammals, birds or fish, thus these products that are deadly to insects are safe to use around children and other pets, when used as directed.
