The oldest and most common control of rodents has been the cat. People have adopted cats as pets for this purpose for centuries. However, some cats may be afraid of large rats, and they may also catch fleas from the rodents. If biological and physical control measures are not effective, use a pesticide which will have a minimal impact on both you and the environment. As with any pesticide, caution is necessary to keep rodenticides out of areas which kids and pets frequent.
Anticoagulant baits are the least hazardous to humans and animals.
There are several forms of bait available. Once the bait has been consumed, the rodent will experience internal bleeding and then die. It is recommended that bait stations be used because they limit access to rodents only. Bait stations hold the bait inside and contain a small hole through which the rodents can climb. The disadvantage of this method is that it may take some time for rodents to die after consuming the bait.
