BASFPT 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.

Best fly killer I’ve ever used. I had a very bad fly problem. Sprayed the windows and doors and the flies were dead in a couple of hours. I had two flies since and they died shortly after they entered the house. This stuff works and is worth every penny!

I have purchased hundreds, if not thousands, of items off of Amazon over the last 20-plus years -- from books to computers to snacks and everything in-between. During that period, I have *maybe* written five reviews. It's just not something that I do.PT Alpine worked so well for me - and SO QUICKLY - that I feel absolutely compelled to write this review and sing its praises.We have had an unusually pesky fly problem this summer. It's not uncommon for us to have a few flies in the house during the summer months - I mostly blame our four dogs - but this summer it has been especially bad. The problem quickly went from minor nuisance to a constant irritant.I tried everything I could think of. I went full-on Rambo with the Bug-A-Salt and, while fun, it seemed like two more flies would pop up for every one that I mercilessly gunned down. I tried the UV light plug-ins. I experimented with all the (useless) home remedies on Reddit. Nothing helped.Then I came across a recommendation for PT Alpine. The Amazon reviews were very promising, and I was desperate, so I placed an order.My friends, please believe me when I tell you that a few strategic sprays of PT Alpine made a near-instant impact. Our kitchen is now a fly-free zone. The patio is littered with so many corpses that it would rival the most ferocious battles of antiquity. There are no more irritants buzzing about the living room (except for the aforementioned dogs).Highest recommendations.
