Large Roach Killer Gel Bait 6 Pack, Fast-Acting Roach Repellent Indoor Cockroach Infestation Elimination, Long-Lasting Nest Destroyer with No-Mess Formula & Placement Stickers

I do not know what kind of bait is used in these things, but it killed all the flies! I watched flies land on the wall, turn around and head for the bait, snack a while, fly away and come right back to the bait. It's like they became addicted. And then I started seeing the results. They were dropping off the wall, couldn't walk or fly or run. They were in some kind of stupor and they all disappeared or died. Fantastic product!

No good doesn't work 😕

I’ve tried several products to combat the problem and this is by far the best one that has worked so far. It’s really easy to use and the only drawback that I would say is that when using it you have to place the pea sized amounts in a corner that is visible by anyone viewing that corner

Doesn't work. Didn't even slow them down

Hard to know, but I believe it is working and easy to place it out dot by dot

Used this product and I haven’t seen a critter since. It’s the truth.

Kills bugs and keeps working long after you apply.

Not doing a good job.
