Outdoor product. I had a big problem with cockroaches. In a very short time after applying it, they disappeared. I recommend you buy it.

Works great. I left some droplets near the sink and so on. The next day, I woke up to a bunch of dead roaches.

Easy to use, the tip of the syringe fits perfectly in the gap of the balcony door. I used it every month to renew the material, and I didn't find a single cockroach all summer. Cheap and effective

Anyway, I put almost all of it in the kitchen cabinets and I see cockroach droppings everywhere in the cabinet and the gel untouched

I had tried countless similar products in all forms (gel, spray, traps, etc)... With this one, I couldn't believe my eyes... within 2 weeks they disappeared because they carry it back to their nest... You place it in multiple key spots, be careful if there are pets (cats, etc) as it will probably be fatal for them too

I had tried it last year and there was not a single one left standing!! Put a little in the spots that need it and after 2 weeks at most, they will all be exterminated without a doubt! I will put some again this year from now on to be covered because soon the cockroaches will wake up again, it’s their season!!!

Excellent product!! Apply it and in a few days even the slightest cockroach will disappear. Maybe 1-2 will appear in their season. Apply again and that's it!!

Perfect product. I had a problem with cockroaches at night in the kitchen. As soon as I put this gel, I see them all upside down every day

Very good for the money. I bought it for the reviews. Effective within 2 days. In the green circle is the cockroach (German small Xanthos) one of the most difficult.

THIS REALLY WORKS!!!!

I ordered two of these Gemmar Dragon things, and used 1 for around the house...we have a huge 250m2 appartment and we found cockroaches.
I did it everywhere: in corders you dont see, and little cracks everywhere, bathrooms and the kitchen.
Everywhere excepts kids rooms (too dangerous with young kids, because its a gel that you can touch).
Just a little bit, a few drops every time.

Next day we already found 3 dead cockroaches, and they were BIG bwaaah :)

Apart from professional spraying, this is the best we have tried!

"Sweet as chocolate"....Immediate results, a few minutes after application the girls came out and tried it. I don't think they carry it back to the nest because they don't seem to make it (they probably die). I agree with - tsit72- Minus one star for the steep price

I saw it from a company that was using it for cleaning and I bought it. It is effective. Minus 1 star due to its price.

Big problem inside the house. Every night, 2 to 3 large ones (American type) would appear. The nest, after a lot of searching, is under the refrigerator and in the dishwasher. After a good cleaning with chlorine and placing this specific product in the affected areas, I already had results in the first 10 minutes. It disorients them and gradually kills them. Around the dishwasher, I put a second dose of medication after two hours because they had eaten it. The product works, and it works well! The issue is patience because with so many eggs they lay, it will take time until the nest is destroyed. I haven't tried any other similar product, but I can say about this one that it does what it promises and has a relatively good price.

I happened to communicate with the owner for some information that I mistakenly entered in the address, and he was truly polite and helpful! And the product was extremely effective just as he told me!

No matter what I tried all these years, unfortunately I always saw them in front of me!!!!!!! And everywhere!!!!!
I've been using it for 3 years, I won't change it. I have never seen NOT ONE.
My problem starts around May, so I put it on a little before the heat starts. And outside the house in the garden on the doorstep. Very small amount in each spot

So I bought this because there was a nursery next to my house that does the same job as other well-known brands, I believe it just changes the brand.
It has a dark brown color, so it stands out easily wherever you put it.
I put very small bait in the attic, and after ten days of opening it, I found a half-eaten, cockroach.
Cockroaches, you should know, function like cannibals, one eats the other when they die, and that's why this medicine is effective because one gets infected and then all of them.
Also, for those of you who have a problem in the kitchen, put it behind the refrigerator because they go and breed inside the motor, which gets very hot in the summer, and in the cabinets under the sink.
