These work well for flies.

They work but smells really bad

These works extremely well. The only downfall is the smell and if it spills it's even worse.

This is amazing the only thing is the smell so don't put near food or people or front door

smells worse than a sewer but it sure does work!

they really get rid of flies, works great

This thing is awesome. It works as soon as I put it up it had flys in it.

I think these attract flies from the whole neighborhood

This was effective in catching flies but it also attracted more than usual and the smell was awful.

These are the best fly 🪰 trappers I have ever found!
