    • Works perfectly – no more cockroaches
Size: (Pack of 1) Style: Bait Gel Killer
This product completely eliminated all the cockroaches in my home — and they never came back. I honestly didn’t expect such fast and long-lasting results, but it worked incredibly well. It’s easy to use and extremely effective. This is one of those products I recommend to everyone without hesitation. If you’re dealing with cockroaches, this really works. ... show more

    • SOMETHING THAT FINALLY WORKS! FOR REAL!!
Size: (Pack of 1) Style: Bait Gel Killer
This is by far the best I have ever used since my infestation began! I have been battling for almost three years! I never leave any food out! I double-bag all kitchen trash, wash out the sink drains, and sweep the floor daily, and my kitchen was being taken over! I even had a service for almost a year, and nothing seemed to work. My daughter did her research and found this product. I ordered it and within 2 days, I could tell the difference! I placed lines and drops everywhere in the kitchen, including under the microwave, the Keurig, the stove, the spice racks, and even several dots under my air fryer. I put it in every small crack and crevice I found. My house is an old country house, and it is near a large open field. I have a waterbug issue at times, but since using this product, all I have found are dead waterbugs, only 2! My only issue with the product is that the writing on the container is so small, and being a senior 66 years young, I still needed additional lighting to read it! I am very pleased so far and will be subscribing to keep the product coming so I can stay on top of the problem until it is eradicated for good! EXCELLENT PRODUCT! GREAT QUALITY! ... show more

    • Highly effective roach bait
Size: (Pack of 1) Style: Bait Gel Killer
Really impressed with how effective this product is. I battled cockroaches in my laundry area for about 3 months and no matter how many I killed there were always more. I found this product and laid it down in various places in the area and they ate the lot but more importantly, I haven't seen a single roach since, not one. Our cat food is in that area which im sure attracted them in the first place but not seeing any roaches with food being there is proof to me that this product killed them all. Top marks. ... show more

    • Terro T502's is "Bait and Switch"
Size: (Pack of 1) Style: Bait Gel Killer
20240928: If I was allowed a 0-star, that would be my new rating. All the other Terro products I have used were great. This T502 may work in perfect LAB conditions but not in the real world. I trashed the unused portion of the T502. Never again will I purchase the T502. 20240830: Changed rating from 2-stars to 1-star. Bait hardened to the point the roaches will need a chainsaw to create pieces to eat. "BAIT" implies they take the poison back to their nest and then the nest residents help consume the poison. This is not the case with this Terro product, unlike other better Terro products. 20240710: I sent terro.com follow-up questions, "My T502 has the consistency of medium hard caramel. Second question, do roaches eat the T502 or just touch the "bait". Terro's response: "Thank you for reaching out to us. Under normal conditions the gel is good for one year. And to your other question the roaches consume the gel. Should you have any further concerns please feel free to reach back out to us." ------------------------- My modified opinion is based on the T502 "dry-out" issues and [email protected]'s response about "drying-out" (20240708). I changed my 3-stars to 2-stars. ----------------------------- [email protected] emailed response (20240708): "Answer: Thank you for this feedback regarding the instructions, it has been shared with our Product Managers. The product should still be effective as it is drying out, but once it is completely dry, the roaches will no longer be able to consume and it should be reapplied if necessary. We do not have a time frame regarding how long it will take to dry out. This will vary based on humidity, how much was applied, what surface it was applied to, etc. This product is not taken by the roaches back to their nest to share with others. " -------------------------------------------------- My Amazon Review Terro T502 Roach Bait (and switch) ? 20240706 1. No paper instructions included. 2. Used internet to find how to allow spray can to function properly. 3. White printed instructions on side of can are barely visible. 4. "Bait" hardens after a day or two. Not sure if roaches can hammer and chisel a piece of the bait for consumption. 5. Waiting on Terro to answer these and other questions via email. I plan to modify my review based on their response(s). ... show more

    • Effective
Size: (Pack of 1) Style: Bait Gel Killer
The roaches were getting out of control. They were living in the refrigerator motor, behind the dishwasher, under the stove, in the trash can somehow. I put this bait in all those places and I haven’t seen a roach in 2days. #massextinction
