In combination with a Cyper or Demon pack I cover 1/4 acre with trees, bushes, low brush places flies, biting flies, gnats, noseeum mosquitos, fleas, and ticks takes care of them. the Bifen is 1oz per gallon and is a great price for the size. I do prefer Proflex but its very expensive...sometimes too expensive.

Sure beats the premixed big box store product of mystery potion. Product shipped promptly. Mixed as per directions and good by mosquitoes.

2oz per gallon in pump sprayer of 2 gallons does my fenced 1/3 acre yard/trees. depending on rainfall, lets say 2x a week i have to reapply every 3 weeks for Mosquitos and gnats. Lasting effects for everything else is much longer. Spraying is nothing fancy, just wand it over the dew in the morning helps the spread, and under tree leaves(mosquito hiding spot). In Florida house Bifen was not effective enough but in Georgia it does great. Only Proflex works great in sub-tropical hands down but it's a small fortune.

This is the best product that I have ever used against fire ants. I use a 2 gallon sprayer filled with 4 ozs of Bifen I/T and if it is sprayed as directioned and the mound is soaked so that the tunnels are filled beneath the ground,the fire ants will be killed totally.

Works great on most outdoor insects and has a residual that kills for months.

Our house is a partly a restored 1784 hewn log cabin. The newer construction has natural cedar siding. It is located in the middle of our 77 acre very rural property where stink bugs have been a major problem for the last 10 or 15 years. I have used other more expensive products with decent results. This product seems to do just as good a job at killing the target species at a lower cost. I applied 6 gallons to our two-story 2200 square-foot home. Dead bodies all over the place.

I just bought a new home in Fort Worth, Texas and we had a lot of insects and around the perimeter. This product worked as advertised. A few days after applying the application, I noticed A LOT of flying insects dead around the perimeter of my home, especially the paved areas. Sometimes I would see a new insect flying into the patio area of my backyard which used to host a lot of other flying critters. But now, when they come in contact with the surfaces that were sprayed, they will start to fly in a strange circling pattern and then eventually die a few minutes later. I used a 3-gallon manual hand pump sprayer from Amazon. I only used what was recommended mixing dosage for a 2,000 sqft perimeter. Make sure to wear your PEE. I used old clothing, shoes, and wore a mask and eye goggles because when you spray overhead the mist gets everywhere so be cautious of that. Overall I'm happy with the product so far.

I have been using this chemical on my mountain home and urban rental. It is easy to mix and apply and seems to be effective for preventing pests. I was paying $500 annually for pest control I can assure at a fraction if the expense.

I've used this (and added Gentrol) two times. The first spray was preventative. The second was in sewer fluid season. There's probably not a season, but for my basement apartment, they seem to surface end of June through the summer. No sewer fly complaints yet. Some background: I've tried the orange gel down the drains daily for months. It did nothing. I deduced they were coming from somewhere else. Customer survive recommended this brand. I have enough product on a basic purchase to last a couple years! Here's hoping this will do it from here on out! I only ranked it four stars. If I see no more flies for the rest of the year, I'll change it to five.

Not much to say other than I have used Bifen for many years and it seems that the insects have a difficult time adapting to it. Works well and does not seem to damage painted surfaces.

I seriously have not seen a mosquito since I used Bifen IT on the perimeter of my yard. I am very happy with the results. Wished it kept flies away too but not complaining!

Seems to work pretty good for major flea problem on the outside of my house. But I have to re-spray about every three days. I'm going to try it with the nygard IGR SOON. Maybe that will help even more.

Didn't kill them all but it reduce the population by 3/4 only sprayed once will buy again?

Summer time, the flies and mosquitoes are back. Used it with a garden sprayer, around the outside of the house. The stuff mixed and spray well, no clogging, has a slight chemical odor that lasted a few hours. The chemical works good, but had to re-spray after about 3 weeks. It eliminated most but not all flies and mosquitoes.

We've followed the clear instructions and have consistently received excellent results especially around the house areas we frequent and also the mailbox, garbage containers etc. We've used Bifen IT with consistent excellent results for over Ten Years.

I have been using this product for years very good all around insect control for outdoor.

Was this review helpful to you?  YesNo

I use every summer. Seems to be best stuff for mosquito control. I use every week after I mow. It says every 3 months or so, but if I use every week, I don't have issues. Live this stuff

Not as good as Tempo SC Ultra. But budget wise it seems fine. I'll probably switch back to Tempo.

Was this review helpful to you?  YesNo

I have used this once, it seems to be ok. However, I don't think it is as good as the Tempo SC Ultra or as long lasting as the Tempo SC Ultra. I wonder if I should have got the oil based Bifen so that it might last longer. The jury is still out on this one.

I’ve bought this product two other times, and it came in the bottle as shown online. I received a very strange and difficult bottle to handle. Awkward to use, at my age. I intentionally chose the straightforward type, but received one with the miserable measuring spout. Not happy with that at all. Love the product and DMO.

Bought this again due to cost and it does work as well as Talstar P.
