Review: BUY BUY BUY ! - I was so frustrated. This year the roaches were worse than I have ever seen them. I was using sprays, baits, roach motels, and nothing that used to work was cutting it. Then I saw this and all I can say is that I am stunned. This killed 90% the FIRST DAY! After 3 days NOT A ROACH VISIBLE. Do not hesitate, this product solved all my problems . Review: Great - I’ve been using this roach bait gel for a short time and it’s easy to apply and convenient to use. The bottle design allows you to dispense small amounts of gel directly into cracks, corners, and other areas where roaches tend to hide, such as behind appliances or under cabinets. The gel is ready to use, so there’s no mixing or complicated setup. I like that you can apply it precisely in small spaces rather than spraying chemicals everywhere. After placing a few small drops in problem areas, I started noticing fewer roaches over the next couple of days. ## Features - KILLS COMMON ROACHES: This cockroach killer indoor home is effective against German, American and Oriental cockroaches - WORKS FAST: Our German roach killer gel bait starts working to control your roach problem within 2 days of application - EASY ONE-HAND APPLICATION: The roach gel bait syringe design allows for one-hand application, making it a an effortless cockroach bait option - NO WASTE OR MESS: Our roach bait gel with an adjustable flow nozzle allows for precise application, minimizing mess and serving as an effective indoor cockroach killer - VERSATILE INDOOR USAGE: This German cockroach killer for indoor spaces is ideal for kitchens, bathrooms, garages and basements ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09F7Q9VSS | | Active Ingredients | Fipronil | | Best Sellers Rank | #1,605 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #39 in Pest Control Baits & Lures | | Brand Name | Terro | | Customer Reviews | 4.3 4.3 out of 5 stars (6,658) | | Included Components | Terro - T502 | | Item Form | Gel | | Item Type Name | T502 Ready-to-Use Indoor Roach Bait Roach Gel Killer - Kills German, American, and Oriental Roaches – 3 oz | | Item Weight | 3 Ounces | | Liquid Volume | 3 Fluid Ounces | | Manufacturer | Woodstream Corporation | | Model Number | T502 | | Part Number | T502 | | Specification Met | EPA | | Target Species | Cockroaches | | UPC | 070923658756 | | Unit Count | 1.0 Count | ## Product Details - **Active Ingredients:** Fipronil - **Brand:** Terro - **Item Form:** Gel - **Item Weight:** 3 Ounces - **Liquid Volume:** 3 Fluid Ounces ## Images ![T502 Cockroach Gel Bait Killer 3 oz - Fast-Acting Roach Killer Indoor Infestation Control for German, American and Oriental Roaches with Precision Applicator - Image 1](https://m.media-amazon.com/images/I/715xDed26+L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Will this help destroy the nest?** A: Yes, Terro will help destroy the nest. When they eat it, they will go back to the nest and die, then they will eat the dead ones and they will die. **Q: Can this gel be use in the sticky roach traps?** A: For best results, this should be applied to cracks & crevices, around windows & doors, under appliances, and in crawl spaces. We do not recommend using it inside of the sticky roach trap. **Q: Are the contents under pressure, or does this work by squeezing (or pump action)? Can I safely transport it in checked luggage?** A: This product is considered to be under some pressure, however it is not an aerosol. We recommend checking with the requirements of the airline as to types of products that can be brought on board. **Q: Gel didn't come out: I broke the lock twisted and pumped but gel didn’t come. Do I have to make a hole on the top? Or I get empty bottle?** A: watch the video listed by Amazon, it shows a little tab you have to break off to be able to use. Don't poke holes in anything. Watch the video. I was running into the same problem. Broke the little tab off and all was well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ BUY BUY BUY ! *by D***E on April 4, 2026* I was so frustrated. This year the roaches were worse than I have ever seen them. I was using sprays, baits, roach motels, and nothing that used to work was cutting it.

I've ordered a lot of crap on here. This, this stuff absolutely worked. I live in an RV and put a few spots out throughout the RV and since that times, months now, I have seen ONE bug. I highly recommend this product and believe me it only takes a tiny bit, pencil eraser size, to do the trick. ## Frequently Bought Together - Terro T502 Ready-to-Use Indoor Cockroach Gel Bait Killer - Kills German, American, Oriental Roaches, 3 oz - TERRO T500 Indoor Multi-Surface Roach Bait Stations - Indoor Cockroach Killer, 6 Bait Stations, Black - Combat Max 12 Month Roach Killing Bait, Small Roach Bait Station, Child-Resistant, 18 Count --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/365831025-t502-cockroach-gel-bait-killer-3-oz-fast-acting-roach](https://www.desertcart.co.th/products/365831025-t502-cockroach-gel-bait-killer-3-oz-fast-acting-roach) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-29*
