BioShield is also available in larger sizes for livestock. BioShield is very effective in keeping black flies, mosquitos, ticks, gnats, etc… away from your horses, cows, deer, etc… BioShield is all natural so it doesn’t have any harsh chemicals that would harm your pets or livestock.

BioShield for pets and livestock is a proprietary formula of Portland Outdoors and is powered by NeuroRx which was developed by pharmacists. NeuroRx works by attacking a neurotransmitter only found 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 shut down of the central nervous system… killing insects nearly instantaneously.

Octopamine is only found in insects. Humans and other mammals, birds and fish do not produce octopamine. NeuroRx is safe to use around children, pets, and livestock but is deadly to insects when used as directed.
