Wondercide - Mosquito and Fly Aerosol Spray - Fly, Gnat, Flying Bug, Mosquito Killer with Natural Essential Oils - Quick Kill for Outdoor and Indoor Areas - Pet and Family Safe - 10 oz - 2 Pack

Oily. Kills bugs instantly. It’s bad when it’s on the floor where you step. It needs to be cleaned so you don’t slip

I use for outdoor patio but recently started using indoor for drain flies and nats. No more irritating bugs. Sprayed in drains.

Does not kill flies it does weigh them down while they suffer on the ground. Makes a terrible oily mess on the walls, windows and floors. When we asked for a refund we were denied and given an explanation of how to wipe up the mess. Terrible product, even worse customer service.

This spray works at killing flies and also has a nice scent so it's not overwhelming to the senses, but it leaves an oily mess everywhere you spray it and you have extra work cleaning surfaces and floors from the overspray.

Living on a ranch we sure deal with a lot of flys. We have tried many sprays and they don’t seem to work very good. We found this spray and seeing as it’s pet safe, our basset hound gave it the thumbs up! Flys HATE this product. It is extremely effective and smells great! My only complaint is that it leaves behind an oily mess. I sprayed it in the light above the sink where a few flys were hanging out. The dropped dead as door nails instantly. A few days later I turn the light on and notice the spray is still there! A bunch of small droplets! I got a rag and wiped it up. It’s great for lasting effectiveness but it will make your tile or wood floor slicker than a slip-n-slide lathered in baby oil so beware!

Works great - even for ants. Pleasant scent and does not appear to negatively impact the dogs when they are outside.

PRO: contact kill - even a light misting seems to eventually kill, the more you soak the insect, the better/faster the kill. If you didn’t get enough on, mostly it’ll knock down the insect and it’ll crawl around until it dies - not sure this happens 100% of the time so that’s when I move in with the swatter (which I’d say is the ultimate pet-safe insect killer…no chemicals at all!).CON: I’ve used various pet-safe insecticides over the years and many use an oil base as a carrier for the kill chemicals - the ones I’ve used all eventually dry (w/in a day or two mostly). This stuff not so much. I sprayed a few flies on windows and it leaves a coating of oil that does not dry. Two days later spray splatter, drips, and fine mist are all still there. Wiping w/dry paper towel just spreads it out. Requires soap and hot water to remove (from glass). I would assume it will leave an oil stain on fabric/rug/carpet/flat-finish painted surfaces depending on how much was sprayed. Not saying other products don’t leave some dry stain but not a wet oil slick like this.Not throwing it out but going to be much more selective where I spray until it’s used up. Trying another product (different brand) to compare but given the high price of this product doubtful I’ll buy it again.

Good
