D-Fense SC Insecticide

Walt Cline - Pest Control Professional Pro Tip: "We sell more D-Fense SC than any other insecticide. It's good for inside and out, it's odorless and economical. One application every 3 months is the norm for this product. D-Fense SC will not work well on German roaches. Use a roach bait called Vendetta Roach Bait or Invict Gold Roach Bait, instead."

Great product
This is our 3rd purchase of this product. Takes very little to make enough for our home and our neighbor. Does a great job keeping stink bugs and the small brown beetles out of the house. It is effective for many months.

Highly recommended product. It works.
Great product. Kills bugs dead. Was totally surprised at how many bugs I found dead following application. I was pleased to find that boxelders, etc. are exterminated also.

Awesome on spiders & millipedes
I've use a commercial pest control service for 20 years, at $300/year. I bought the D-Fense and a sprayer from DIY Pest Control and did it myself. So far, everything is just as they said, existing spiders have all died, and I'm finding new visitors dead in their tracks. Easy to mix & spray. Colorless & odorless. I used it all around the outside of house, in the garage, and in the finished basement. Scary at first, spraying it all over the place. An hour later you have no idea it's there. I followed the web site recommendation for mixing rate, not the bottle. Great stuff!!!

The jury is still out
I have only used the product once. I am bothered with stink bugs. I have definitely seen less so far this fall after using this insecticide. I will use again before winter gets to Pennsylvania.
