I put it down we shall see. Will update. I'm using now 6 years big cheese. The other big cheese blue ones take few days to work. Rats are smart and they will watch and wait other rat eating it first. If thers more than one. To make sure the foods okay. They don't all eat it right away. Why people till hear feet. Rats will make,e sure it's safe to eat first by watching a rat who's ate it. These red blocks in the pot are meant to be stronger poison and faster. So may work fast but also other rats will see them die before they themselves have eaten it. I like the tub with way to seal the poison. I don't like the bags on there big cheese.not easy to open with gloves on. I don't like the blue blocks bag not being sealable and easy to open. Observation These red blocks the blocks are massive and far too big. Rats dont eat it at the bait box usually, they grab and run. generally climbing to lofts if in the house. Not everyone is fit enough to getup a loft to put poison up there. Herr, Rats are climbing up sewage pipes to houses, in the country.every sept. Rats they take the cube with them. These blocks are size wise far too big for anything but big rats to lift and hold a climb with using their mouths to hold the block. i suggest to shrink the block sizes so the rats are able to lift and carry the block with their mouth, totake the poison with them. Warning!!! I DONT recommend using poison blocks outside. We need to protect the rest of nature wildlife. Other creatures can eat it if outside even in a bait box. including hedgehogs. Dead rats are eaten eaten by owls, hawks, crows, seagulls.you will poison other wildlife using these outside. If you do use outside Never ever use poison blocks outside without bait boxes. If can poison birds, cats, foxes, rabbits etc. Birds will pick it up eat it then poison their young. Inside same only use bait boxes in places kids and pets have no access to. you can poison pets, kids if your not careful. Always use gloves when touching bait and bait boxes its still poison. Wash your hands after taking gloves off. . Review: No rodents found yet - Large blocks ## Features - Contains benzisothiazolone.

I can't help you. Suggest you contact seller😊 **Q: Does tha bait have to stay dry** A: It’s waxy so will stay dry but that then attracts slugs which eat it. They are unharmed but hedgehogs might eat them. Best keep them dry. I’ve built special tunnel boxes with restricted access so only rats/mice can get in. Happy to post pictures with dimensions if required. These poison blocks have a central hole. I thread wire through five or six like a necklace and then tie it down otherwise the rats will just remove the bait and store it. If it’s tied down, then they have to eat it. **Q: Would a grey squirrel fit in here?** A: squirrels are quite agile but I think the hole is to small **Q: What is the active ingredient and what strength % in the Ultra Power Rat Poison? Can't see it anywhere.** A: benzisothiazolone. May produce an allergic reaction To humans ## Customer Reviews ### ⭐⭐⭐⭐⭐ Waiting to see how fast they work *by L***D on 26 March 2026* First time using these more powerful big cheese.

The professional pest controller used various poisons by Rascal but none were touched). This poison is slow acting, though - over 4 weeks. But as a lure onto effective sticky traps, I can recommend this block bait. Of the 13 rats killed so far - one was poisoned and the rest all got lured and trapped on adjacent sticky traps. ## Frequently Bought Together - The Big Cheese Ultra Power Rodent Killer Bait Block - 15 x 20g, Kills Mice and Rats, Pest Control Product - Rat Killer Refill for Bait Stations- Super Strength Rat Poisoning, Red - The Big Cheese All-Weather Block Bait - 10g x 30 Kills Mice and Rats Damp-Proof, Weather-Resistant, Blue Difenacoum - The Big Cheese Ultra Power Block Bait Rodent Killer Kit, Refillable Bait Station and 3x20g Brodifacoum Blocks, Rat and Mice Poisoning Blocks, Fast Acting, Red, Biodegradable, Indoor and Outdoor Use --- ## 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.hr/products/57897100-ultra-power-rodent-killer-bait-block-15-x-20g-kills](https://www.desertcart.hr/products/57897100-ultra-power-rodent-killer-bait-block-15-x-20g-kills) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-22*
