Controlling Roof Rats on Poultry Farms using ContraPest, A Contraceptive Bait
Roof rats and other rodents are a common pest in agriculture, causing extensive amounts of damage and losses. Poultry farms provide an abundance of resources that attract rodents but our ability to control them in these locations is limited. Bait stations can become sources of nesting or go unused i...
