When we use a product that offers outstanding results , we like to share it. "Mosquito Barrier is the best thing since sliced bread". That's a quote from one of our customers. Honestly guys, it is that good. Most folks ask for it year after year. Outdoor events can be held with confidence. We spray everything 30 feet high & lower. Results are immediate. Instead of getting bitten to death, all of a sudden....not bites whatsoever. It lasts several weeks, and it's totally safe. I use a J-D9 gun to spray it. Under decks, eaves of houses, grass, small trees & shrubs, etc. Basically anything 30 feet tall & under. Another advantage is you can spray it during work hours instead of going out at dusk to spray an insecticide that does not last. While this is not a "plug" for anybody, we buy ours from Tech-Terra (a lawnsite.com sponsor). Thought I'd share something we believe in 100%. Try it. You will be amazed. rscvp after you try it.
