This is the best thing I have found for flying insects in the home. It killed our fruit flies that had come in from the cold last week. It's safe around kids, the elderly, and pets. Our household was a good example for it's use. No more toxic sprays for us. A great buy.
I love how kills on contact but it needs to come in larger bottles so it is economical in quantity. I'm willing to buy a larger bottle for the inside an outside. Can it be used directly on inside and outside plants? Very good product. I haven't seen a gnat in any area I sprayed.
this is a great study, but I nearly gave up trying to get the plastic guard off the lid. I have to pull the spigot thingy out of it to get to the benefit shelf. I nearly broke off the first parts of the form to get. I didn't get one buzz in my ears or an itch in my leg, we were able to. it's with it's weight in file
this is an oil based product and if it is on the floor watch your step. my son fell because he slid on its oily residue it left behind. the smell is awful. i feel that in order to kill the flies i had to spray them direct contact. spend the extra dollar or two and get a product that works without the threat of injury .
Well, as many of us do, I figured out how to activate the sprayer and shot some product into the air (in the kitchen where the majority of the gnats were) and headed upstairs to bed in hopes that my morning coffee ritual would not be disturbed by little gnats buzzing my head. Morning comes, I head downstairs to get the coffee started and almost break my neck as my feet start slipping out from under me! I look down and see a lot of wet spots on the tile kitchen floor and wonder where it came from. Ohhh, I think to myself. Did that come from the gnat spray? I grab the spray where it says read directions before spraying. In the fine print it says “Dont spray into the air.” What? I read further and see that you're expected to wait until the gnat lands and then spray it from up to 18” away. Seriously??? Is one supposed to stand at the ready all day watching and waiting for a gnat to land?? And afterwards you're supposed to wipe the surface clean from the mess the spray left. Its just not pheasible for me; I have a life and dont intend to spend it waiting for gnats to land with an aerosol spray can in my hand. Spent my day washing all surfaces where that awful residue landed.
PLEASE READ I STRUCTIONS! If you use it as a general air spray it gets on EVERYTHING- %26is hard to remove even gets inside anything electronic and keeps it from working! Do not just spray around! Finally threw it away. Didn't work well,and made a huge mess
This STEM product if horrible. It does not take care of flying insects and it is like spraying baby oil into thr air. It ruins all papers, furniture, and anything it lands on after its sprayed into thr air. It's greasy and disgusting. Do not buy this! !!!
BEWARE: This is a Slip / Fall hazzardous product. I have slipped on the vinyl flooring more than once around the door to back patio I sprayed: OIL OPEC would appreciate the amount of oil this spews which makes it NOT for indoor use as marketed. Mosquitos were not deterred - but my cat was. Cleaning every surface and window in effort to [try] to remove the oily film it left. Don't recommend. And especially not indoors.
The only way this works is if you spray it right on the bug. It leaves a greasy residue everywhere it's sprayed. If I have to Chase the bugs, I might as well use a fly swatter and save myself the time and trouble of cleaning up the surfaces where the spray lands.
Absolutely worthless. It states you must spray the insect directly. You tell me how you are going to spray knats directly? It leaves an oily film on everything. my husband sprayed in our kitchen, and it made the floor slick. It didn't kill the knats.
