To protect themselves, certain plants have developed highly effective defense mechanisms against potentially harmful insects. That's the idea behind SENTRY Natural Defense®. SENTRY has harnessed the power of these natural botanical extracts to produce a line of flea, tick and mosquito control products.
Years of testing went into the development of SENTRY Natural Defense®. Many natural active ingredients were tested and the best performers were combined to form a natural pest control barrier for your pet.

HOW DOES SENTRY NATURAL DEFENSE® WORK?
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.
WHY IS IT SAFE?
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.
