When used as instructions dictate this is an excellent home insect repellent. One treatment can last for several years making this a good value. There is no odor, nor visible insects afterwards !

I use the product in a farm setting with exposure to most common crawling and flying insects out there today. With Fall here, seems like all of them want to get inside of a building too! Demon WP is easy to apply by simply dropping the packet into the sprayer and adding the specified amount of water. After a short period to dissolve, a few shakes are necessary and then you're off to spraying. Simply follow the directions on the Demon WP package and you're covered. I've found the product to be long lasting as it doesn't seem to wash off easily as bugs are still meeting their demise after several rains. Kind of interesting to see the variety of dead critters that show up on the sidewalks after the application. Be certain to read the cautionary information as well and you'll be coverd. Highly recommend Demon WP.

I bought this product to administer on my dock (I live on a large lake). Using the product with a gallon sprayer allows the product to be sprayed into dock posts, steel girders, around my boat lift, and other parts of my dock ceiling/posts/flooring. I've noticed a significant decrease in spider webs which was my primary reason to invest in this product. Just be careful you don't overspray into the water or on colored furniture.

We do our own pest control with this stuff, spraying the perimeter of the house, indoor baseboards, and under the sinks. It works really well and we rarely see any bugs inside. I live in central Texas and there are MANY creepy crawlies if you don't spray.I worked for a pest control company years ago and this was what they regularly used for customers. Save your money and do it yourself like we do. I wouldn't pay for a commercial service unless it was a specialty need, like termites. Just get a cheap 1 gallon sprayer with a wand and you're good to go. Typically, we spray every 3 months.

I use this product every 6 months inside and outside my home. I have no issue with any bugs. Spaying ones home is a necessity in FL. This product handles it all. It is pet safe ONCE IT IS DRY. Very easy to use. You will need a 1 gallon spayer to use this product. 1 packet covers my inside and outside of my 1400 sq ft home. The only negative or downfall to the product is that it can leave a slight white residue on your carpet (if you have carpet).
