I have a large yard. Can this be mixed for use in a hose-end sprayer?
cathryn l on May 21, 2018
BEST ANSWER: I'd recommend Bifen XTS for outdoor as it is oil based and more resistant to being washed away. Bifen IT is better for indoor applications (water based). Either is concentrated however and meant to be mixed with water and sprayed.

I have not used it with a hose end sprayer (I've just used a hand pump sprayer) so I can't say from experience but it is possible - you just have to make sure the sprayer has the correct water/product ratio.

A shopper on Mar 30, 2018

Honestly, does it kill & eliminate German Roaches & for how long?
Kim P on Jan 17, 2018
BEST ANSWER: It helps... I had best results using it in combination with a gel bait (advion) to kill them first and applying it as more of a barrier about once a month. I live in a somewhat wooded neighborhood in central NC so I don’t think completely getting rid of them is realistic but it’s a lot better. For a while I’d see a roach as frequently as once or twice per week, now it once every few months, usually in the fall when it starts to get cold. Good luck.

BEST ANSWER: Bifen XTS is a higher concentration of Bifenthrin and is a petroleum based product, they are both mixed with water. Bifen XTS is not recommended for inside use and can potentially harm lawn and plants because of the oils. What you are trying to control and where will determine which is a better choice for your needs. I believe the Bifen IT is a more general use product that is more versatile and better option.
I need an Ant killer product?
A shopper on Sep 24, 2017
BEST ANSWER: Sometimes it is helpful to know what type of ant you are needing to control, Fire Ants you can use a drench of the mound that will work very well. If you are trying to prevent ants, then Bifen IT would work really well to apply to the perimeter of the house and the turf.
