Bests & Worsts Reviews from Amazon

These fly strips were great, and I may even purchase more next summer. I have mostly positive things to say about them, but there were a couple of drawbacks. On the positive side, the adhesive is insanely sticky. If a fly lands on it, it's not going anywhere. They also stand up to the "clear" promise. If you put them directly on a window, you can see that they are there, but they are very unobtrusive, and I didn't mind having them in my home when guests came by (until they had captured flies of course). As far as the negatives, the adhesive that is on the front of these is the same adhesive on the back, and it's a little strong for "around the house" purposes. It can't be attached to paint or any surface you don't think could weather the razorblade that I had to use to get the remnants of the adhesive off of the windows. For the record, the strip that was left behind on the window came off with one swipe of a glass razor, but I'd have paid an extra 50 cents for these to have masking tape adhesive on the back to make installation/removal a little easier. There's also nothing to lure the flies in. Normal fly strips "stink", for lack of a better word, and it draws the flies to them. These rely more on the fact that they can be placed on a window where a fly is likely to bump into them. It worked, and it worked well. Within a few days, every fly had bounced into one of these on sheer chance, and I was set, but it didn't happen instantly. If you want something quick, you might be better off with those sickly sweet smelling film canister style rolls from the hardware store. Like I said, I'll almost certainly be buying more of these next year. If you get them, just make sure they only go on glass/stone/steel.
