Rodent infestation starts, especially when the crop is at stage of maturity. They destroy the crop by uprooting the plants. To reduce this problem, the sunflower (Helianthus annuus) plants are intercropped with the main crop. Birds like Falcons are attracted to sunflower (Helianthus annuus), to eat the seeds of sunflower. In a way they also eat the rodents, thus helping the rodent control programme.

"Birds of prey are famous for feeding on rodents. Hawks and falcons hunt by day, and owls typically hunt by night. Owls are especially dangerous to rats because they hunt at the same time that rats forage for food."

"Famously, birds of prey feed on mice and rats. Raptors, including hawks, owls, eagles and falcons, are common predators. Red tail hawks, found across most of North America, and American kestrels, the smallest falcon in North America, will hunt rats by day. The barn owl, known for its characteristic round and white face, is a common nocturnal predator."
