## Description

Product Description Professional Grade Rat & Mouse Killer Powerful Multi-Feed block UKs Strongest Multi-feed Poison available to the amateur market. 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 Built for Performance, Designed for Safety The Professional Way to Bait 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. Professional Rodent Control Starts Here Safe & Secure Rodent Control For maximum safety, OPKILL Rodent Bait Blocks should always be used within a lockable bait station. Designed to help restrict access to the bait, these tamper-resistant boxes provide a secure baiting solution for use around homes, gardens, sheds, garages, lofts and commercial premises. The durable station design helps protect bait from the elements while keeping it securely positioned, allowing rodents to feed naturally without disturbing the bait placement. This not only improves bait management but also helps reduce unnecessary contact with the bait by non-target animals. Ideal for both indoor and outdoor use, OPKILL Bait Stations feature a robust construction and lockable lid, making them a practical choice for homeowners, landlords, pest control professionals and commercial users. ✔ Lockable Tamper-Resistant Design ✔ Helps Protect Children & Pets from Accessing Bait ✔ Suitable for Indoor & Outdoor Use ✔ Keeps Bait Securely Positioned ✔ Weather-Resistant Construction ✔ Ideal for Rats & Mice ✔ Professional Quality Rodent Control Solution

Review: Great product - Works perfectly
Review: Worked Amazingly - Unfortunately I had some mucky neighbours who weren't putting their bins out and their garden was an utter disgrace. This attracted mice, possibly even rats. They ended up running through the the 4 apartments here. I managed to get about 3 of them with traps but they soon got smart to the traps, getting the bait without triggering them. I was so stressed. I felt horrid knowing they were running around in my flat. So I found these on here. The first day I got them I placed 1 in the cupboard under the sink as I had caught one there before and within an hour it was gone. I managed to use another 4 that night so they were obviously taking the blocks back to their nest. I swear to god the next night I put more out and the one I put there is still there and I haven't seen or heard anything since. Because it was indoors I just placed the blocks openly. But if yoir using them outside you need to place them in a box trap because if a dog or domestic pet was to eat them it could be deadly. But I hope I never have to buy more of these ever again, but if I do I know they definitely work. I would seriously try these of you have an infestation.
