PRODUCT DESCRIPTION: Granulated material which is designed to last longer in the rain and sun than ordinary sprays. Bifen will release slowly into treated areas and provide over two months of control.

TARGET PESTS: Just about everything.

WHERE TO USE IT: Around homes in turf, flower beds and mulch areas. Anywhere grubs are active where armadillos are digging. By treating the turf you will kill off the very food source luring armadillos and they will be forced to find food elsewhere.

PESTS CONTROLLED: Ants, armyworms, billbugs, centipedes, chinch bugs, crane flies, fleas, fire ants, leafhoppers, mealybugs, millipedes, mole crickets, pillbugs, scorpions, sowbugs, spiders, ticks and others.

RATE OF APPLICATION:    A 25 lb bag will treat as much as 1/2 acre (approximately 20,000 sq/ft). That breaks down to about 1.25 lbs per 1,000 sq/ft.

So lets say you wanted to treat a 10 foot band around your homes perimeter, you’d first want to calculate how many feet you have. If the home is 60 feet wide by 40 feet deep, it would have a 200 linear feet perimeter. If we multiply that by 10, we come up with 2,000 sq/ft. That means it would take about 2.5 lbs to treat a 10 foot band around a home that size.

HOW OFTEN SHOULD IT BE APPLIED:   This will vary depending on the problem. So for initial infestations, renew the granules once a month. But once the problem is under control, treat once every 3 months to make sure the problem pest does not return.

Hi, I have a small dog (12 pounds). If she accidentally ingested some of the granules would they cause her harm or make her sick? I have a spider and roach problem and want to get it under control, but want to make sure the pellets don’t harm her. I was also going to get the Delta spray – is it best to have both for the exterior? Thanks.

@admin: I am having a problem with Black Widows on the outside of my house. Will this product be helpful in getting rid of them? Thanks.

Spencer Hansen @ 1:12 pm #

@admin: Thanks for the quick reply. So far all of my black widows have been no more than 1 foot of the ground….around the bottom of the siding and where the concrete blocks meet. So I’m thinking the granular might work. Thanks for the other suggestions as well!

Are these granules safe to use over a septic tank and drain field?

What is the rate of application with a hand spreader?

I have springtails in my kitchen area. We had a leak under the sink and it was infested. Currently replacing the cabinet/drywall and sink. Hoping to rid all wet/moldy areas. Can I lay this behind my sink area? What would be the best alternative for inside use to treat springtails?

@admin: Should I order the PT-221 or the Phantom? Both seem very similar. Thank you – Katie

You were mentioned on another website for controlling Cicada wasps. I have an infestation of them. Will your product get them before they reemerge in late spring? Also, is your product not to be spread in vegetable garden areas?

End of November in NC. Is it too late to spread Bifenthrin to eradicate grubs? Moles have suddenly become very active and are destroying a lot of lawn.

Is this effective against grasshoppers?

After many attempts to rid my patio and yard of springtails, even using a Terminix service, I researched your site and followed your recommendations using Bifenthrin and Cyonara spray. It appears we have beat this little devils. Thank you so much for your help!

Having a bit of a springtail issue and just purchased bifen granules and Cyonara RTS to treat outside. As I was removing mulch from up against our foundation to replace with gravel, saw a TON of springtails in the mulch. We have a weed liner under the mulch. Will the granules work if we sprinkle on top the mulch and liner? Will they sink into the soil beneath the liner without having to pick it up?

Have a springtail problem. Really dont see a lot inside but tons on my deck, window sills, house siding, patio etc. We have mulch and plantings all around the house. SO, if I spread spread granules around the house and in the mulch should this start to control the problem? Where are you located?

I have found 3 brown recluse spiders in my home over the last couple months. They were all in different rooms. I have an inside cat. I also have an outside cat. How can I treat this problem without harming my animals?

Have had a major problem with infestation of spring tail insects located in the master bathroom of a our home that just happened about two years ago. The bathroom sits on a cement slab covered with ceramic tile and is located on the southwest corner of the house. Tried other treatments, but nothing stopped the flow of spring tails into the bathroom. Last year, used a treatment of Bifen Granules and Cyronara outside and it knocked down the flow significantly. Still see a few spring tails so have continued the treatment this year. The improvement from last year after the treatment to this has been dramatic thanks to your products. Hope this input is helpful to others.

Bifenthrin is great! Had an absolute outbreak of moles in my lawn while away on vacation. Found Bifenthrin at and used it. All mole activity stopped within a week of using it and had no more activity for six months. I now use twice a year and have eliminated the pests tunneling in my lawn.

Works great! Finding dead bugs everywhere and the main one we were after(kissing bug) now dead.

We have seen a few kissing bugs in our backyard. Is this an effective treatment for us? We have about an acre and would use a spreader to cover our entire yard.

I have an infestation of black beetles in the yard and around the outside of the house and in the garage. I am in NC and with all the recent rain and humidity, they are getting worse. What can I use that is safe for the dog, but will kill them? Tired of sweeping up dead beetles.

Work great. We bought this kit for the Millipede. It works very well, although we have been used it for two weeks only. I like the result. Thank you for solving my bug issue.

Very Effective Product. My home is surrounded by woods. Moles tunnel into the lawn in search of grubs. At the first sight of a tunnel I apply Bifenthrin and in a matter of a few days the tunneling subsists. I typically need to apply every 4 to 5 months. Easy to apply and very effective.

We live on a remote island with a sandy beach about 1/2 a mile long then rocks on both sides. Our large dog is getting eaten alive by sand fleas. Will Bifen be ok to use up to the water line? Will it harm fish?
