Kaput Combo Bait Mini Blocks deliver the first rodenticide that also eliminates fleas for an all-around approach to pest control. The bait is effective against Norway and Roof rats; house mice, deer mice, and white-footed mice; voles; and the fleas that reside on these rodents and may be carriers of infectious diseases. Studies have shown that in times of aggressive baiting with traditional rodenticides, flea populations actually increase, contributing to disease outbreaks as the fleas search for new hosts. Kaput Combo Bait Mini Blocks prevent the spread of these diseases by targeting the fleas with imidacloprid, as well as effectively killing the rodent population with warfarin. These active ingredients are effective at low concentrations, making them exceptionally safe for use in and around the home. However, in cases of accidental poisonings of children or pets, Vitamin K1 is a readily available antidote. Formulated with paraffin, the Kaput Combo Bait Mini Blocks are moisture-resistant and durable. The blocks have ridged surfaces to facilitate rodent gnawing, and a hole through the center allows the blocks to be fastened down inside a bait station. Quality grains ensure that the rodents are easily attracted to the blocks, and continue to feed on the bait.
