I purchased this product (at the best price I could find btw) in a effort to knock down the amount of mosquitoes in my yard. I live in the woods, with lots of leaves and a nearby swamp. Last year's as well as this year's spring have been very very rainy, which means lots of water around to breed Mosquitoes...Nothing I could do about that. They would swarm my car windows upon entering my driveway. It was unbearable to even walk from my car to the house, parked inside an attached garage. Using our yard was hopeless without heavy application of high Deet % bug repellents, and even that wasn't enough to stop from having to constantly swat at them. Not fun, practical, or good for us, especially our young kids.
I generally don't like using poisons, but we honestly were to the point of talking about moving as the mosquitoes were simply too much.
I applied Bifen as directed to the underside of my deck, underside of all my plants in the yard, and the perimeter plants and fallen leaves in the woods. Took about 6 gallons in a pump sprayer. That means 6 oz of Bifen. The effect was noticeable the next day, and even more so the following day. I can now use my yard freely without repellent. Still have a few mosquitoes, but NOTHING like it was.
I did get eaten alive while spraying. This stuff does not appear to knock them down right away. Don't be surprised or disappointed by that. It will work.
I've also used this around all my points of entry on my house to control ants and spiders. Which it appears effective as well. As a bonus, I've gone through my yard and sprayed a few second burst down the holes of the large ant population that was killing my grass and have seen dramatic results as well.
I continue to see a normal amount of (for my area) dragon flys in my yard, tree frogs on my deck, as well as toads in the grass, birds by day, and bats at night. I can only assume they are largely unaffected, their welfare was a concern for me as I enjoy ALMOST all the wildlife in the yard.
I've had no problems with the product clogging my sprayer. It seems to mix well at the proper ratio. I pour in measured amount of product, then add required water. I usually give it a couple shakes too for good measure.
With the absurd amount of flooding rain my area has continued to receive, its been about a month, and I feel I need to reapply. Dry season the effects will likely last longer. No worries though, as to date, I've used a total of maybe 15oz, out of the 96oz jug. At this rate, the 40 some dollar jug will last me longer than it's shelf life of a couple years. I'll likely offer some to my neighbors for their yards as it will benefit all of us to have a larger treated area.
