Our bait block is a standout performer in the world of rodent control. Our blocks have been professionally formulated to achieve optimal results against the targeted pests and all of our products are quality tested by professional pest controllers prior to public release. This means that you can be confident in the product that you receive delivering the maximum impact on the rodent issue whilst enabling prolonged use if the problem is more widespread. Opkill Rat Bait Blocks are a highly effective rodent killer and can be used with equal effectiveness in the treatment of both rats and mice. The wax based block leads the way against many other baits on the market and is regarded as being one of the strongest baits available in the UK! This bait is classified as a Multi-feed poison meaning that unlike many other baits on the market this poison is specifically designed to deliver a lethal dose of poison to a rodent through a process of several feeds. As a consequence this increases the kill rate and encourages other rodents to feast! Our research has found that you are less likely to find a dead rat or mouse around the home as they often return back to their nest to fall asleep, reducing the risk of dogs and other wildlife picking up the rodent and causing secondary poisoning. Our product is specifically designed to reduce bait shyness, to maximise bait take up and ensure that a lethal dosage is ingested. In addition this will ensure delivery of poison to each rodent and therefore ensure effectiveness from day 1! This poison is specifically designed to deliver the right amount of poison necessary and that one pack should be more than enough to kill up to 20 rats. Contains: (Bromadiolone 0.0025% w/w & denatonium benzoate 0.001% w/w.) UK Registration: UK-2016-0986-0006 Rodent Bait Stations Required Under the regulations in 2015, It is now a requirement that all rodenticides are to be secured in tamper proof lockable bait points if not used by a professional operative. This is to safeguard against accidental ingestion by non-targeted species. The Opkill bait boxes are versatile, compact and robust. They are made from high quality poly-carbonate plastic offering an affordable alternative to our larger metal bait box range whilst maintaining the effectiveness of use. These bait stations have been designed specifically to withstand even the toughest conditions that mother nature throws at us. Opkill bait stations are an essential component to enable a comprehensive and safe treatment plan. Using Tamper resistant bait stations ensures children and pets are safeguarded against accidental contact and can be used internally and externally. Use against Rats & Mice Palatable wax & grain Attractive smelling Weatherproof Bromadiolone 0.0025% w/w, Denatonium benzoate 0.001% w/w. HSE Approved UK- 2016-0986-0006 Antidote: Vitamin K1 These wax blocks enable the poison to be suitable for both indoor and outdoor use. The wax coating provides a waterproof barrier against some of the harshest elements preventing spoiling, meaning that this is far more suitable for use in external areas unlike conventional grain baits and other poisons available on the retail market. These blocks are ideal for use in areas of high levels of activity such as garden, sheds, lofts, voids, cellars and outbuildings, these easy-to-use pre-formed blocks simply fit onto rods for housing in our Lockable Rodent Bait boxes, which are specifically designed for this purpose. This reduces the risk of contact with non-target species, as well as pets and children, maintaining security against access over a sustained period of time.

They are ususally gone within a couple of days so don't get much chance to get wet! **Q: Once ingested, how long does it take to kill a rat? Do I have to worry about them dying in my walls and stinking for weeks?** A: This can be a problem, we have had them in the roof and the smell was awful. Well I seem to have fed them quite a lot. refresh the bait every month or shake to box to see if it's empty. It does work well and you must remember to change the type of poison every 6 months to stop them from becoming immune. **Q: How many needed to kill a rat? I placed 7 out two nights ago and ALL were taken, done the same last night and nothing has been taken this time?** A: Hello, This really depends on the level of infestation and how much has been ingested at once. As a multi feed this can take up-to 24-48 hours to work but typically 1 bag for approximate 5 rats however can remove an infestation of up-to 20 if evenly distributed. Our advise would be to check the baits in a weeks time and re-apply. Hope this answer helps Kind regards Opkill Customer service. **Q: Can you deliver to Spain?** A: I don't know, you would need to contact the seller for the answer ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for Rats and Mice *by M***K on 27 May 2026* Good stuff.

The packaging is neat, and the product quality feels solid. It helped address my rodent problem quickly and efficiently. Having two packs is very convenient for longer-term use. Overall, a dependable option for anyone needing effective pest control. Highly recommended. ### ⭐⭐⭐⭐ Appears to work, but slowly. *by R***L on 3 April 2022* Put this in proper secure bait boxes and all of the poisen has gone when checked the following week, but the rats are still running around for a while afterwards. I get that there are probably a few rats but it does seem to take an entire packet to get rid of one or two rats. So it does work but seems to take effect really slowly which surely is not humaine for the rats. Did try the humane rat traps but had 10 rats at one point (2 adults and 8 babies), and caught two over a period of a couple of months so had to do something more drastic. Do feel bad but they had their chance to be relocated to a local wildlife area. ## Frequently Bought Together - Opkill Rat Poison & Mouse Killer TWIN PACK 600g Strongest Bait Available Weatherproof Fast Acting and Safe For Professional and Domestic use (Professional Choice Blocks 30 x 20g) … - The Big Cheese All-Weather Block Bait - 10g x 30 Kills Mice and Rats Damp-Proof, Weather-Resistant, Blue Difenacoum - RatKil Rat Poison (6 x25g) Rat Bait & Mouse Poison Grain - Strongest Maximum Strength Rodent Killer - Fast Acting, All Weather, Single Feed Bait Sachets --- ## 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.gr/products/139517525-rat-poison-and-mouse-killer-twin-pack-600g-strongest-bait](https://www.desertcart.gr/products/139517525-rat-poison-and-mouse-killer-twin-pack-600g-strongest-bait) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-06*
