    Mouse and Rat Poison 20kg Sacks

    Effective rat poison and mouse poison for professional and agricultural use, supplied by Collins Nets in bulk 20kg sacks (two 10kg bags per order). Available in Jade Grain (Bromadialone) or Ruby Grain (Difenacoum), both manufactured by Lodi as multi-feed, second-generation anticoagulant rodenticides, formulated on whole grain with added aniseed to draw rats and mice away from other food sources on site.

    Grain bait like this is the practical choice when you need to cover a large area, target hard-to-reach spots where traps aren’t an option, or deal with an infestation that’s outgrown domestic products. Because it’s a multi-feed anticoagulant, it also remains effective against rats and mice that have built up resistance to older, first-generation poisons such as Warfarin.

    Please note: we sell this product as a 20kg sack – you will receive 2* 10kg sacks.

    Jade Grain or Ruby Grain: which should I choose?

    Both grains use the same 0.005% ready-to-use whole grain formulation and work in the same way, so the choice comes down to active ingredient.

    Jade Grain uses Bromadialone. Ruby Grain uses Difenacoum. Many gamekeepers, farmers and estate managers rotate between the two across a site as part of good resistance management, or stick with whichever has worked well on their ground previously. If you’re not sure which is right for your situation, call us on 01308 485422 and we can talk it through.

    Application rate

    For rats, use bait points of 90 to 100g. Place them 10 metres apart, reducing to 5 metres where infestation is high. Once laid, don’t move or disturb bait points for several days. If there’s no sign of rat activity near a bait point within 7 to 10 days, relocate it to an area with higher activity instead of leaving it in place.

    For mice, use smaller bait points of 20 to 30g, spaced 5 metres apart and reducing to 2 metres in high infestations. Mice are naturally curious, so relocating bait every 2 to 3 days during your inspections and refills tends to improve results.

    Check all bait points regularly within the first 10 to 14 days, and replace anything that’s been eaten, damaged by water, or contaminated by dirt. As an anticoagulant, this product works gradually rather than on first contact, so rodents need to feed on it over several visits before it takes effect. Regular monitoring gets better results than expecting an instant kill.

    Is this rat poison safe to use around pets, livestock, or children?

    This is a professional-strength rodenticide, and it needs to be sited and handled with care. Always use a secure, covered bait station rather than laying bait loose, and keep it well out of reach of pets, livestock, children, and non-target wildlife, in line with CRRU stewardship guidance. We stock a full range of bait stations designed to keep bait protected. If you suspect a pet, child, or non-target animal has ingested any bait, contact your vet or doctor straight away rather than waiting for symptoms to appear.

    Certification and stewardship

    Proof of certification is required. No bait will be dispatched until all requirements are fulfilled. Orders placed that do not meet the requirements will be refunded.

  • FAQs
  • How do I buy the larger quantities of poison?

    We cannot sell large quantities of vermin poison online because we need to see a copy of your certificate or farm assurance details. The best way to order poison in bulk is to call us. This way we can provide you with an email address to send your proof of competence. You will also need to fill out one of our declaration forms. To find out the latest CRRU approved certification and farm assurance schemes please visit the Think Wildlife website . Please visit www.elearning.lantra.co.uk/LODI to gain certification.

    How do I get a certificate to buy vermin poison?

    You will need valid certification to purchase vermin poison. Please see the following link to obtain certification: www.elearning.lantra.co.uk/LODI

    Do I need certification to buy this rat poison?

    Yes. This is a professional-strength anticoagulant rodenticide, so we cannot supply it in bulk online without proof of competence. You'll need either a recognised CRRU-approved certificate or membership of a farm assurance scheme that permits rodenticide purchase. Please call us on 01308 485422 and we'll provide an email address for your certificate or declaration form, and confirm everything before your order is dispatched. Orders placed without valid proof are refunded. If you don't yet hold a certificate, you can register for training at elearning.lantra.co.uk/LODI. For the latest approved schemes, see the Think Wildlife stewardship guidance.

    How do I buy larger quantities?

    We cannot process bulk rodenticide orders through the website, as we need to see your certification or farm assurance details first. Call us on 01308 485422 and we'll talk you through it: we'll send you an email address to forward your proof of competence to, and ask you to complete a short declaration form. Buy 10 or more sacks (200kg) and you'll qualify for 10% off.

    What’s the difference between Jade Grain (Bromadialone) and Ruby Grain (Difenacoum)?

    Both are multi-feed, second-generation anticoagulant rodenticides formulated on whole grain with added aniseed to draw rats and mice away from other food sources, and both are effective against rodents that have developed resistance to first-generation poisons such as Warfarin. The difference is the active ingredient: Jade Grain uses Bromadialone, Ruby Grain uses Difenacoum. Many gamekeepers and farmers rotate between the two on a site as part of good resistance management, or choose based on what's worked well on their ground previously. If you're not sure which is right for your situation, give us a call and we'll talk it through.

    How does this rat poison work, and how long does it take?

    As an anticoagulant, it works by gradually disrupting the rodent's normal blood clotting, rather than killing on first contact. Rats and mice need to feed on the bait, usually over several visits, before it takes effect, so don't expect an immediate result. In practice this means checking your bait points regularly, ideally within the first 10 to 14 days, topping up anything that's been eaten, and relocating bait if you're not seeing activity within 7 to 10 days. Patience and regular monitoring get better results than expecting a quick kill.

    Is this rat poison safe to use around pets, livestock, or children?

    This is a professional rodenticide and needs to be handled and sited with care. It should always be placed in a secure, covered bait station rather than laid loose, kept well out of reach of pets, livestock, and children, and away from watercourses and non-target wildlife, in line with CRRU stewardship guidance. Never leave sacks or loose bait accessible. If you suspect a pet, child, or non-target animal has ingested any bait, contact your vet or doctor straight away rather than waiting to see if symptoms appear. We stock a range of bait stations designed to keep bait secure and protected.

    How much rat poison do I need for my property?

    That depends on the size of the infestation and the area you're covering, but as a guide: for rats, use bait points of 90 to 100g spaced 10 metres apart, reducing to 5 metres where activity is high. For mice, use 20 to 30g points spaced 5 metres apart, reducing to 2 metres in high infestations. A 20kg sack (supplied as two 10kg bags) will typically cover a good number of bait points across a farm, estate, or rearing site, but every situation is different. If you'd like help working out roughly how much you'll need, call us on 01308 485422 and we're happy to talk through your setup.

    How should unused bait be stored and disposed of?

    Keep any unused bait in its original packaging, in a cool, dry place, out of reach of children, pets, and non-target animals, and away from food or animal feed. Don't use bait that's been damaged by water or contaminated with dirt; replace it rather than relying on it. Unused rodenticide should not go into general household waste. Check with your local council or waste authority for the correct disposal route for pesticide products in your area.

    What is CRRU, and why do you need proof of certification?

    CRRU stands for the Campaign for Responsible Rodenticide Use, the UK stewardship scheme that governs how professional rodenticides like this one can be sold and used. It exists to protect wildlife and pets from unnecessary exposure, and to slow the spread of resistance by ensuring products are used correctly. That's why we're required to see proof of competence, either a CRRU-recognised certificate or valid farm assurance scheme membership, before we can supply this product in the quantities professionals need. You can find the latest approved certification and assurance schemes on the Think Wildlife website, and register for training at elearning.lantra.co.uk/LODI.

    Do I need to use a bait station with this poison?

    Yes, we'd always recommend it. Siting bait in a secure, covered bait station rather than laying it loose protects it from weather, keeps it away from pets, livestock, and non-target wildlife, and helps it stay effective for longer. It's also part of following CRRU stewardship guidance correctly. Have a look at our range of bait stations to find one suited to your site.

    Is there a bulk discount, and how quickly will my order arrive?

    Yes. Buy 10 or more 20kg sacks (200kg) and you'll get 10% off. For delivery timescales on bulk rodenticide orders, please call us on 01308 485422 once your certification has been confirmed and we'll give you an accurate estimate for your order.
