The Science behind SENTRY Natural Defense.

To protect themselves, certain plants have developed highly effective defense mechanisms against potentially harmful insects. That's the idea behind SENTRY Natural Defense.

Years of testing went into the development 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 only found in insects. Neurotransmitters control heart rate and metabolism. Insects such as fleas, ticks and mosquitoes produce a neurotransmitter called Octopamine. The natural oils found in SENTRY Natural Defense block Octopamine - Causing a complete breakdown of the central nervous system - killing insects almost instantaneously.

Why is it safe?

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