Generic bifenthrin 7.9 from TSC(liquid). Add 1 oz of mineral oil per gal of spray to the mixture. The oil makes the residual last longer outdoors. If spraying indoors, dont add the oil.


TSC

Agree. I spray this around my hunting camp and shooting houses. Works well.

I alternate Suspend SC and demon WP and that seems to work well. Demon WP leaves a light white residue

Suspend Polyzone SC is what Ives used this year. It’s done the job.

D-fense SC. Cheap, effective and one pint has lasted me for years. It’s a synthetic Deltamethrin, even safe for indoors.

There are many good products out there. You can go to domyown.com and read all the reviews on the different products. Also has customer Q&A which I found helpful.

Bifenthrin 7.9% is the standard. You can get the cheap stuff at tractor supply or buy the original (Talstar) or copycat Bifen. They all work the same.

Suspend is good and I've used it for years inside. I'm currently using a product called Demand CS and I am finding more dead bugs than I've ever found before with the other products. I try to change up every so often.

Demon is a good product too. But it leaves a white residue that stains my dark wood floors so I stopped using it inside.
