Very effective
The label on this stuff says you should allow 1-2 weeks for it to eliminate your roaches and reapply if necessary. I had a serious roach problem. I seldom used my kitchen without seeing at least one run across a countertop. I put four or five globs of this gunk out and (three days later) I haven’t seen a roach since. I’m still kinda keeping an eye out, but so far I’m pretty impressed. The applicator is easy to use if you read the instructions. As is my SOP, I read them AFTER my first couple of attempts. Don’t be like me. I would buy this again and I would recommend it to a friend if I had any.

Forget about calling pest control again!
Cockroaches are disgusting and such a nuisance. After using this product, I didn't see another cockroach after just 2 days. It was easy to apply, and the results were impressive. I'm very happy with how well it worked and would definitely recommend it to anyone dealing with a cockroach problem especially apartment living with people living on all sides of you. Before this I used many products without any success. I also placed many workorders where pest control came without any success. This product is hands down the best and effective on all types of cockroaches!

Worked really good.
This is by far the best thing I’ve ever purchased to get rid off cockroaches. However, it is really difficult applying this gel bait. The release point malfunction towards the end. I couldn’t use all the gel bait.

Good product
This is a good product but it doesn’t have enough if you’re going to do it in lines how I did. Your supported to do dots but the bottle was squeezing to much as much as I tried not to squeeze a lot. But it’s not a bad try to buy two. There’s less roaches but didn’t get rid of all because again there wasn’t enough.

PU!! 😂
Gawd! It smells like poop and looks like poop I don't know if I'm going to be able to stand the smell very long I'm going to try to keep it down for a couple days and then that's it I can't use this anymore I don't even know how it works yet but I'll do an update five stars for now because it's easy to apply, But you also need to be careful about how fast it comes out cuz you should do small dots and I put a big plop the first time . I don't have a big infestation anyway I just see one baby one here or there but that's not a good sign either never see any of my kitchen that's all in the bathroom and I think the lady next door to me is infested the way she's talking.

works but very little product!
I have always used TERRO for ants and it is very effective. This summer, I have been seeing quite a few roaches so I decided to try this. Almost immediately after applying, I noticed it was attracting roaches so I think it is for sure pretty effective. My issue is the bottle and the amount in it....my trigger lever didn't seem to work that well and it only dispensed a very small amount. I was only able to cover about 6 inches, and that was with just dotting it. The bottle feels like it might have more product but nothing is dispensing. At this rate, I would need a dozen bottles to do the area I wanted to treat. The odor is semi strong when dispensed, good for attracting bugs, and it doesn't seem to linger so it isn't off-putting. I did notice dead bugs within the first 24 hours so product does work, just not happy with the dispenser or the tiny amount in it.

Working as it designs for.
So far been only 1 week, we can see the less C ROACH around our dogs feeding spot. We feed our 2 dogs outside, we need to prevent the INVADER to comes inside of the house then we'll be in trouble. Times will tell if the product working.
