Prevasyn is an insect repellant that makes life miserable for bugs. It features a highly concentrated mix of natural oils and capsicum oleoresin (pepper extract). The latter ingredient is the key — soft-bodied insects and mites can't stand its agitating properties.
When applied regularly, Prevasyn keeps bugs from eating, laying eggs on or otherwise inhabiting leaves. It also makes them more mobile, which increases perspiration and thus absorption of other pesticides (e.g. Exile). Prevasyn is one of the few insect repellants on the market that has both natural oils and capsicum oleoresin — and that you can trust to control your bug population naturally and safely.
