BASF PT Alpine Fly Bait, Fast Acting and Long Lasting Up to 30 Days, Ready to Use Pest Control Spray for House Flies, Fruit Flies, 16 Ounce

So far, PT Alpine is the best product I've tried to control flies on the patio. I've tried sticky traps and the hanging bags that smell like rotten eggs.. neither of them worked for me. I also picked up a can of Quickstrike granuels, which I've read works well, and I will leave a review on that one after I get around to trying it. PT Alpine is not perfect, but it gets the job done. The product makes 2 main claims: 1) that it attracts flies and 2) that it kills flies. It does NOT seem to be a good attractant at all. They will lick the sprayed surface if they happen to land on it, but they don't seem to be attracted to it. When used by itself, flies still buzz around but never land on the sprayed surface. If you put some food or garbage out to attract the flies, and then spray it, it works great. Within 15 seconds or so after landing on the sprayed bait, the flies will start twitching and fall over motionless. It is VERY effective. I'm sure it works so well on trash dumpsters because the stinky dumpster itself functions as the attractant, not the fly bait. It's peculiar how this product works. I've noticed that it doesn't always seem to kill flies right away.. sometimes they will come back to life and start break dancing or twitching after appearing to be dead for 20+ minutes.. but then they will once again stop moving, and they never get back up and fly away. Overall, it's a highly effective product for fly control as long as you have something to attract them to it. Though calling it "bait" is a bit of a misnomer, since it doesn't seem to do anything to lure flies. **UPDATE** Photo added to my review of my solution some general notes about fly control, and my comments on Quickstrike. Firstly, Quickstrike granules work almost identical to PT Alpine (extremely well), so either product will do the job, depending on how you prefer to approach the problem. It only works if you add liquid to the granules and let the flies eat it, but that means there's clean-up to do and it still requires an attractant. I chose to stick with PT Alpine for reasons explained below. The fly problem I'm trying to solve is keeping them off the patio so I can sit/grill in peace. My solution (the attached photo - an early prototype) was to repurpose an empty cashew can. Inside the can, I put a styrofoam cup filled with stinky bait (more on my bait below). I cut a hole in the lid of the can and put a scrap piece of window screen under it. I set this contraption out in the grass, spray the lid and screen with PT Alpine, and then let the flies do their thing. Why did I do it this way? Because I never have to clean up fly carcasses! The flies go after the smell but can't get inside, they lick the lid and screen and then die in the grass and get mowed up later. Another big bonus is that I use very little PT spray, so it will last a long time. In my testing, PT remains very effective for at least a week if not longer, which is impressive. As for my bait.. since I had some of the hanging fly traps left over that you fill with water, but instead of returning them, I removed the pouches of attractant and poured them into a shaker jar. I read somewhere that it is dehydrated fermented eggs. I shake a little bit of it into the styrofoam cup with some apple cider vinegar. The cider vinegar not only attracts flies, but also gnats (which PT Alpine also kills), and the stinky stuff helps a lot. I didn't want to use anything sweet that might attract ants or bees. Apple cider vinegar is effective and slow to evaporate. This is working well for me. Whatever product/method you use, here is the key to mastering fly control: Almost any product will work as long as you have a good attractant. Fly paper works great IF you put it near something stinky. PT Alpine works IF you spray it near something stinky. Quickstrike will work IF you put in something stinky. But nearly all products require you to regularly clean up hundreds or thousands of fly corpses, which is never fun. So that's why I did it the way I did it, and there is still room for improvement. The 2nd most important consideration is: Flies like shade if it's hot, and sun if it's cool, so put your solution where it will work best. I hope my tips help others! Good luck, and get creative.

This is worth every penny with the upcoming summer months - the flies will attempt to be a nuisance, but I am ready for them. It works each time perfectly - I just spray the areas where the flies normally rest at the front door or garage, especially when we have cut a lot of grass that needs to be picked up by the garbage trucks. This is my third bottle over the past few years - a little goes a long way, and one bottle lasts 2-3 summers. I always wear goggles and a mask when using this product. I hope you find this useful.

This stuff is great. I'm an exterminator but I specialize in termites so I asked a friend what to use for flies and he recommended this product. Sprayed some on a paper plate and put it where the flies hung out and them went to work. Got home from work and there were alot of dead flies. Would buy again.

This is a the most wonderful anti-fly spray! It is also an attractant! This works so good! The flies dies quickly after going to the sprayed areas! My professional bug sprayers used to charge me $25 to spray 6-10 areas with this same stuff! Now I can do it myself at such a lower cost. This even kills gnats! At night, If I had a lot of flies and/or gnats I would take a piece of foil or parchment paper and put old food or fruit or even a little bit of dog poop (hey i know that is gross but flies love it) on the foil and then spray it all with this spray. Come morning, i threw away the foil/paper and then cleaned up so many of the dead flies and/or gnats! Problem solved! Sometimes I would carefully take the foil/paper outside near the back porch to get rid of the flies outside. Also I would just spray the concrete or flower pots to kill the flies. One time I roughly counted over a thousand dead flies swept off my back porch! No kidding! You won’t regret buying this product! It works so well!

This is absolutely the first product that I have purchased that actually kills flies! We live in Texas and always have problems with flies. We sprayed this on some fruit and put the plate outside. Probably killed over 100 flies in 12 hours! So excited!

Had to request full refund- product did not even spray first time I tried - it’s full but no pressure to spray out - very disappointing as I had high hopes being in Florida for the summer! Update! Im updating from a score of 1 to 4. The 1 was due to can not spraying at all when it came but company gave full refund and did not require product sent back. I was able to take off the tip and get small amounts to come out can on top of outside garbage can. The next morning there were dead flies everywhere so I did same thing on window in living room which is where if one fly gets in that’s where it goes. It’s been about a month and I still find a fly here and there in window dead from this stuff. I’m about to give them another chance and buy another can hoping it has no issues because this stuff works and keeps working! I’m Florida heat it’s badly needed

This product was recommended on the Nextdoor app. Our community just had an influx of flies in the last couple of weeks. I’m so grateful that I learned of this product. It works like a champ! I knew we had flies in the house because I would kill about five of them a day with a fly swatter. Sprayed this around our windowsills. Got up the next morning and had over 50 dead flies. Had no idea there was so many in the house. Well worth the price.
