within 3 days we had thousands of flies. You really can't smell the manure that is inside but they work wonderful

Works great. Make sure you use it outside, it does have a nasty smell to it, but works great!! This is my third one.

That's minus five stars worse thaa worthless. Attracts all the flies in the neighborhood and two go in. Net result: I have ten times more flies

Filled two of these within one week. Works best in shade. Hardly any flies left. I don't know where the flies came from, but they are all gone now.

I keep it by the compose pile and lagoon, it fills up in a week. I suggest not putting it near your house, mine is at least 100 ft away.

Attracts the flies , kinda smells so don't put inside. We have by garbage cans so flies don't go inside cans.

This works really well almost too well. We had so many flies trying to get in to the bag but it works.

Set this up outside for a few days, unattended and when I came back it was FULL of dead flies. The smell is strong, but it does get the flies!!

[This review was collected as part of a promotion.] Notice the difference as soon as I put them up No flys in my house or Patio

Best fly catcher ever! It attracts the flies and they can't get out of the bag Keep away from house as it stinks!!
