    5 of 5 Stars   It's amazing!
    October 9, 2008

    I bought Bifen IT because I saw it so highly recommended on this website. I had seen at least one cockroach each day since moving into our new house, so I knew that it needed spraying. The instructions for the Bifen IT product were clear and easy to understand. I also got a 2-gallon sprayer to use, and it worked really well. I sprayed around the foundation up to 3 feet and about 2 feet away from the house, along with any other cracks and crevices around doors, etc. I haven't seen any cockroaches in the 6 weeks since I sprayed. It's amazing! I did find a dead one outside the house around the perimeter of the porch. This stuff really works. For the price, it's a bargain, and you can save yourself a lot of money by taking the hour or so to completely do your house. I plan on re-spraying every 3 months to keep the bugs out. If you're looking for a good deal on pest control, do it yourself with Bifen IT. I also had some questions about how to use it and the customer support people here on the site were very prompt and helpful.

    5 of 5 Stars   Outstanding results on spiders, mosquitos, ants, fleas/ticks
    June 18, 2010

    I own a campground in Texas, and I have been using Bifen IT for several years. I mix 1 ounce of Bifen IT per gallon of water and spray a fine mist on the lower branches of the trees in the campground (up to 6 feet off the ground). The mist that does not land on the tree branches falls to the ground, so I don't have to spray the ground. I treat the campground once every 6 months, and I have absolutely no problems with any insect. It kills mosquitos and ants almost immediately upon contact, and it takes about 30 seconds to kill spiders. When spiders are sprayed, they usually remain still for 15 seconds. Then they begin to feel the effects of the insecticide and their legs start moving frantically back and forth. At the end of 30 seconds the spider is dead. I'm not talking about little spiders. The spiders we have around here have bodies the size of a golf ball. By the way, I should mention that I add 1/4 cup of Dawn liquid dishwashing soap to 15 gallons of mixed insecticide. The liquid soap helps the insecticide stick to the foliage. Excellent product!

    5 of 5 Stars   "Secret" solution
    February 21, 2008
    Verified Purchase

    I live in South Florida and about 4 years ago I noticed a 'new' variety of ant which came in fast and furious. The first year wasn't terribly bad but the second year they had multiplied 5x in numbers. I saw a pest control truck at a neighbors house and asked the guy what he knew about this new ant. He called it the "Caribbean Crazy Ant" (I looked it up on the Internet and sure enough, that was the 'new' ant). He told me that he could control this ant with a "secret" solution, and by the third year I called him for help. I live on a 1.3 acre landscaped lot with many trees, bushes, plants. He sprayed my yard and all the foliage for $200. I guess he thought that I would not attempt to spray this huge yard myself so he actually divulged his "secret" solution. He told me he used Talstar. So back to the Internet I went and found the generic Bifen IT brand. I ordered it and sprayed my own yard the next year for less than $30. The ants stayed away from my house and I will use this product each and every spring from this point on! BTW: of course, not only did it control the crazy ants, it has kept all other pests away as well!

    5 of 5 Stars   Great stuff
    June 22, 2009

    I like this better than Malathion and Sevin. I spray our lawn, perennials, annuals, shrubs, trees, rain gutters, under our deck and foundation with Bifen IT. I'm on a wooded acre and spray as much of my property as I can. I give everything a good wet spray with a hose end sprayer which offers more coverage than a tank sprayer. I spray a few days after a rain when everything is dried out. I've always thought that the rain and moisture breeds mosquitoes so that is a good time to spray them. There is no odor. But it's the insect protection that is fantastic. We spend a lot of time outside in the yard and gardens. We also spend a lot of time on our back deck at night. In the past it would be unbearable. This stuff kills bugs dead and keeps killing which seems like weeks at a time. Pesky mosquitoes and gnats are history. If you wanna be able to spend time outside and those flying insects are a problem then this is the stuff you need. I just hope the state doesn't outlaw it.

    5 of 5 Stars   Extremely effective
    June 15, 2008

    I use Bifen IT to control fleas outside where my cat hangs out (front porch and adjacent yard area). It has proven to be extremely effective when applied every 3 to 4 months during the spring and summer. I highly recommend this product.

    5 of 5 Stars   Working great!
    May 31, 2006

    I have applied the Bifen IT using a hose end sprayer at the rate of 1.5 ounces per gallon and power sprayed the entire property. Two weeks later I made another application concentrating more heavily on three feet up the side of the house and a three foot band around the house. Using this method and this product seemed to abate my scorpion problem. My plan is to do another application a month after the last which will be in two weeks from now. Last weekend I did find some dead scorpions that were on the perimeter wall and one live one that was very slow. So this seems to be working. I assume if I can control them outside they will not be inside the house. Oh yeah, I did use delta dust in all the crevices and in the attic just in case these were entry points.

    5 of 5 Stars   Bifen Holds Up To It's Billing
    August 26, 2009

    I was in the pest control industry for eight years and so as an experienced person who has using pesticides such as Demon EC - a synthetic pyrethroid insecticide, I have to say that Bifen IT is fantastic. It was recommended by my brother, a pest control operator, to treat a problem I had with carpenter ants. After applying it as directed (1 oz per gallon) I was able to successfully cut down the population to zero. Obviously it will need reapplication since the EPA has regulated that these chemicals be biodegradable but it's certainly worth the effort. You don't need to hire a company to control your pest problems. Buy this product and follow the directions and you'll be delighted with the results.

    5 of 5 Stars   Works very well
    March 4, 2008

    I use Bifen IT to control roaches and other insects in my home. It dries clear with no stain or smell and kills many kind of insect invaders . The price is right and I feel safe having it as a indoor insecticide around my family and pets once it is dry. I have found it works very well, and I don't have the cost of a exterminator that probably uses the same insecticide .

    5 of 5 Stars   Great product at a great price!
    August 24, 2008

    This stuff, Bifen IT, works great! We had white-footed ants here, and I thought they were just going to be part of Florida living. When the little buggers first moved to town even the state entomologists were scratching their heads! One even stated that they were almost IMPOSSIBLE to eradicate! Whoever invented Bifenthrin should get a gold medal! Not only are the ants history, but I can't even remember the last time I saw one of our lovely American cockroaches (those beauties are sometimes over 2 inches long!). I only have one complaint: now all my neighbors want me to spray at their homes, too! GREAT PRODUCTS, GREAT PRICES, GREAT SERVICE... thanks to DoMyOwnPestControl!

    5 of 5 Stars   Great Service
    April 26, 2010
    Verified Purchase

    I haven't used Bifen IT yet, but this is the same chemical that is in Ortho "Home Defense", that is effective yet non-toxic to animals and people. I have used the Ortho product a lot, including for dry wood termites. Using Bifen IT, you can mix up the same solution for a little over $1 a gallon compared to $8 a gallon for the Ortho product. Local professional exterminators use the same chemical for general insect control, both in liquid and granule form. Also, I received good and prompt service from DoMyOwnPestControl.com, and I will be ordering more products from them. Their website encouraged me to tackle my termite project rather than paying very big bucks to the termite companies.

    Bifen IT works great for mole crickets. One application in the evening and the next morning I had dead mole crickets on the concrete drive.

    5 of 5 Stars   Works so far
    June 28, 2010
    Verified Purchase

    I started to notice more and more bugs/spiders/ants coming into the house. Rather than paying someone 100+ dollars to do it, I looked into a DIY alternative. Being that the house hasn't been sprayed before, I did 1 oz per gallon. I assumed it was working, as I sprayed I saw spiders running for their lives. I didn't think a spider could move that fast. It's been about a week and I haven't had anything in the house. For the amount it makes and how effective it seemingly is - I would highly recommend this in the best bang for your buck category.

    5 of 5 Stars   Awesome...
    June 21, 2010

    I own a motel, and bugs were a big problem for me. We have 1000's of pill bugs (AKA roly poly) infest our property every spring and millipedes every fall. One application of Bifen IT has completely wiped out the bugs... I don't see a single bug out there... This product is great!!

    5 of 5 Stars   Better than the others.
    June 2, 2009
    Verified Purchase

    My uncle told me about this product. Since Diazinon isn't available anymore I had to find something new for the home and the work shop. I have used Bifen IT now for a year and it is a better product than what I used before. We had a time with spiders for awhile but now have them under control. I use it around my trees for ants and in my work shop for spiders. I also use it in my dog kennels and there are no ants or bugs around. It works great at label recommendations in a pump up sprayer.

    5 of 5 Stars   Fabulous
    September 4, 2011

    This works GREAT and FAST. I used it heavily on the outside, inside and garage of our three bdrm home. Have found ( within 24 hrs) nothing but dead insects ( ants, roaches, spiders, silverfish, etc.) . we didn't know we HAD some of the pests we found dead or dying. What great product. It is true, as many have already stated, that the mixing instructions are not clear. Needs to be addressed. However, to be safe, I OVERdid the amount of Bifen the "instructions" seemed t be calling for, per water portion. Either way../IT WORKS and FAST. We live in Central Florida where it rains hard and often in the summer. Rainfalls and winds have done NOTHING to effect the potency ( though the Bifen has dried, is invisible...) outside. I watch ALL bugs stop in their tracks and rythe in pain until they die where they stand after just a few minutes. Amazing stuff. It does not stain walls, carpet, baseboards at all whatsoever. Just keeps working invisibly. Will be getting more for sure, if and when we need it. It surprisingly even has kept mosquitoes and most moths away outside,too, as I sprayed it on the outside patio lights and a small section of the surrounding wall. Get it. You will NOT be sorry. Keep AWAY from your pets for drying time!!!!!! Bug free and, happy, Missy and Dan. Orlando, FL

    5 of 5 Stars   The only thing for Florida Fleas

    This is the only product I've found that keeps the sand fleas under control in our barn. After an Internet search, I came across this product. Wish I'd found it sooner. Would have saved a bundle!

    5 of 5 Stars   My fav broad spectrum
    September 18, 2012

    I use this for indoor and wood since it's water based, and Bifen XTS (oil based) for outdoor as a GP pesticide, mostly targeting earwigs, crickets and ants. Please do not spray your flowering plants, this stuff will kill off bees easily. Keep it on the ground. Ants will find ANY missed spot to invade. Take care to keep veg. from touching your walls, around support poles (like porches) and utility penetrations. A wide band a few feet up the exterior walls and out a couple feet has been very effective.

    5 of 5 Stars   Mosquito Killer!!!
    April 29, 2013

    I have suffered from allergy to mosquito bites as long as I can remember (40+ years) with a distaste to repellants due to hassle with remembering to use them. WOW! this stuff knocks them out stone cold. It has been a week and a half now and I have seen no more than (3) in the yard and they used to wait beside the door by the dozens waiting for anyone. I also added the Nyguard for good measure and I can't say how happy I am that me and my children can truly enjoy being outdoors without being eaten alive.

    5 of 5 Stars   Japanese Beetle Wipeout
    June 30, 2010

    Bifen IT worked great on the beetle infestation we have every year. We have tried many different chemicals and natural remedies to no avail. Bifen is the answer for us. Also did a great job on all other pests.
