Question: Will this work on backyard small flies?  We have a new yard so is it OK for the grass and to use where my kids play?
Document: I've used this product many times and I'm really satisfied with the result. I use it in Florida for all kinds of critters in the yard and it works great. I also use it to control spiders around and under a deck, and it seems to keep them at bay. Buying in this quantity makes this stuff really reasonable, and the only down side is this big bottle doesn't have the measuring unit that the small bottles do. Other than that this is the way to go.
I have a chinch bug problem in my St Augustine grass, so I researched ways to stop the damage. A few lawn care forums recommended a product with Bifenthrin as one solution. So I came to Amazon, and decided to give this Bifen a shot.This product should be used with great care according to all I've researched about it, so I made sure to use the proper protective gear (gloves, mask, goggles, proper clothing).
At the farm come August the flies start their congregating! We spray all the eaves and the base of our home with the Bifen as soon as they start, then again about a month later and voila.......the flies do not bother anymore! We are fly free (so to speak) till the next season!Thank you Bifen.
We saw immediate results. My workshop tools were covered with spiders and their webs, but not now! It is so nice to work without the little critters crawling around and on me. I would recommend it a hundred time over.
That is great considering I was finding numerous bugs in each 1 X 1 foot area of grass previously. Definitely worth the price.
Worked great for my target insect (mosquito). I am surrounded by woods and would have to literally run into the house to avoid them, now I can enjoy my yard. Great stuff!
Works great on fire ants. Add two or three tablespoons to a 1 gallon sprayer and spray dead center on the hill for 15 seconds. Next day the nest is dead. Doesn't work on any other ants.
Best bargain I have gotten on a product of this type. I was paying twice the price from a local store. Product worked great in my yard and i had immediate results. Great buy!! !
Kills a lot of bugs.... but you will need to treat fairly often for continued results. I would say between 30-60 days. I got it mainly for cutworms in my grass, but it helps with the ants, scorpions and all sorts of other creepy crawly's.
OK, it's poison. What's not to like? I do like the container over the Talstar packaging. It allows you to pour out unmeasured amounts so that you can pour it into your sprayer that does the premix ratio.
Answer: no
