Review: IT WORKS VERY WELL - IF YOU USE IT CORRECTLY - This is a solid product. This is not designed for infestations or ant hills. It is a product designed to prevent entry of insects into your residence and eliminate individual insects that have entered. While this may help the odd case of colonized insects, it really is made for those solo runners that snuck in when you weren't looking. If you have an infestation or a mess, your insects are doing more than entering your house, they are living in it. Perhaps if it was sprayed around the house like the floors were being watering your floors it would work on infestations...but, PLEASE DON'T DO THAT, it wasn't designed for that use nor was that dosage tested for human/animal exposure. Consider calling an exterminator for infestations (100s+, colonies, groups of insects, etc.). And as for ant hills, either remove them, or buy poison for ant mounds. Are there ant hills in your home? That seems like a different problem. After you've taken care of cleaning things up, then protect your residence from the entry of new insects. You'll see this product is WONDERFUL FOR THE JOB. I've used it for years, one home in a very wooded, shaded area, one home in the south. Works like a charm...spraying as others have mentioned...seasonally. This product works by leaving a residue, so if what you spray it on (baseboard, perimeter of home covered in leaves in the fall, edge of home outside, etc.) is cleaned, blown away, excessively rained on...some or all of that residue will be removed...particularly overtime. Be aware of your specific situation and adjust your application frequency accordingly. IF YOU CREATE A BARRIER, THEY WILL NOT ENTER. (Read the label for all the insects covered...it's extensive.) 1. Clean up your outside and inside space a little of non-permanent items, pulling things from the perimeter (toys, anything that shouldn't be on the floor or ground basically). Eliminate debris and items in which insects hide, make webs, etc. 2. Spray the OUTSIDE perimeter and along the border of every door and window. 3. Spray the INSIDE perimeter, along the base boards, of your whole house (closets, pantries, bathrooms included). Then spray a barrier between rooms (around the door frame). Lastly, I understand the frustration that might occur if your wand or applicator never came. Exchange it with desertcart, try a spray bottle, etc. I've been using this with pets. Label says that IT MUST DRY BEFORE IT IS OK WITH PETS. Please remove them from the area while you apply. If you have a pet roach or tarantula I don't know what to tell you. All the best, and good luck with your application.

### ⭐⭐⭐⭐⭐ I wholeheartedly recommend.
*by B***H on January 28, 2026*

Does a great job!! My exterminator just quit showing up and wouldn’t answer calls or texts. So I saw this product on Amazon and decided to try it. Arrived on time and I immediately sprayed my house as instructed. I haven’t seen a bug since. I think those exterminators weaken their product so as to come more often. I’ve already saved 2 spray jobs after 5 months and still no bugs. Great product. I still have over 75% in the jug left.
