Very convenient to get this delivered. Arrived perfect, no leaking and my old gun attached to the new refill jug with ease! Effectively rid us of our tiny ant parade.

Kills bugs and repellent for little bit
Color: Large Refill
Kills bugs! Works pretty good. My hubby loves this stuff. Seems to be pet safe but ONLY AFTER IT DRYS. Do not spray this with pets in clear view... Please!! Washes away with rain or spraying with hose.

Keep bugs away
Color: Large Refill
Good insect killer that helps keep bugs away. It’s easy to apply and works well, though it may take a little time to see full results. Overall, I’m happy with this purchase.

Loyal to this product
Color: Large Refill
I have used this for as long as I as I know. I love the spray nozzle. I love the big bottle. Usually purchase a bottle a year. It lasts a long time once it is sprayed. I use it inside and outside the house. Ants, wasps, mosquitos, spiders have been killed and deterred from coming back. There is no scent. The big bottle is worth the money. ... show more

Great!! Love this stuff
Color: Large Refill
Stops the stink bugs and many other bugs from entering my home. I use it outside too. They come into contact with this and shortly drop dead. Bottle doesn’t leak. It’s very easy to use and lasts a long time. I apply more often like about every month to keep that bug Britten strong.
