Birds are Better Than Pesticides

One of the major scourges that farmers face is crop damage from insects. Farmers spend massive amounts of money on pesticides to get rid of the pests that invade almost every crop they grow. There is also a significant problem with rodents in some crops, and again chemical elimination of rodents is expensive and does a great deal of collateral damage. The solution to all of this is birds. Birds are better than pesticides.

God has always built into the natural environment a way to keep insects and rodents in check. Predators prevent the overpopulation of these pest challenges to human farmers. When humans kill off the predators, the only recourse is using chemicals. New studies have shown how vital birds are to the control of insects and rodents. Birds are better than pesticides. Here are some examples:

FLOOD CONTROL DAMS AND LEVEES – Ground squirrels and gophers burrow under dams and levees, causing the collapse of these structures. Chemical use of anticoagulant rodenticides cost Ventura County, California, $7500 a year and also killed coyotes, bobcats, and mountain lions. So instead, the county installed raptor perches to attract owls, hawks, and falcons. Studies showed that those birds were 67% more effective in controlling rodent burrows and saved $7500.

INDONESIAN CACAO PLANTATIONS – Yields of cacao, used for making chocolate, have increased by 290 pounds per acre after adding bird boxes to the fields.

EUROPEAN APPLE GROWERS – Growers have reduced caterpillar damage by 50% by adding nest boxes that attract insectivorous birds known as great tits.

COFFEE BEANS – Farmers in Jamaica added bird boxes and reduced the number of coffee berry borers, increasing profits by $126 per acre.

CALIFORNIA VINEYARDS – Pocket gophers and voles were damaging crops up to $58 per acre. A single family of barn owls placed in a nest box killed 3,000 rodents in a single year. Armyworms are a problem for U.S. Vineyards as well as for beet growers. In California, nest boxes have attracted bluebirds that eat 2.4 times the number of armyworms as areas without bird boxes.

WALNUT GROVES – Moth Larvae are a problem for walnut growers. Placing bird boxes eliminated four times as many of the larvae as other methods.

Humans have created many problems by not using God’s methods of controlling pests. Research shows that chemicals which cause cancer and other issues are not nearly as effective as birds in eliminating the scourges farmers face. Birds are better than pesticides.
