Top Secret BioShield Spray 4 oz.
BioShield is powered by NeuroRX. NeuroRX works by attacking a neurotransmitter found only in insects. Neurotransmitters control the heart rate and metabolism. Fleas, ticks, mosquitoes and bed bugs produce a neurotransmitter called octopamine. NeuroRX blocks the octopamine, causing a complete shutdown of the central nervous system killing insects nearly instantaneously. NeuroRX is safe to use around children and pets but is deadly to insects when used as directed.
