Ruby Grain 25 contains the multi feed active Difenacoum that gives users the confidence to treat a rodent infestation in more sensitive areas/ homes where pets, animals and children may also frequent. The active ingredient is lower in toxicity to other actives and rodents will need to feed multiple times to hit a lethal dose. Each 150g pouch contains 6 x 25g grain sachets, enough for 1-2 x rat bait points. Medium to high infestations require a number of bait points. Bait refills may be required to replenish any bait taken. Once bait-take has stopped, the infestation has been controlled, so bait must be withdrawn from the bait stations and disposed of correctly. Always read the label.
