Termites' Attraction To Small Amounts Of Carbon Dioxide Lures Pests To Their Deaths

as. The pellets, buried at corn planting time, steer rootworm larvae off-course.

Bjostad's recent discoveries with termites and rootworm points to the possibility that many soil-borne insects also rely on CO2 to locate food and shelter. If so, the gas could be used to steer other agricultural and household pests away from places they do harm.

"Manmade insecticides assume the pests will come into contact with the chemical and die," Bjostad said. "This is a case where we're using the pests' own genetic predispositions to elements that already exist in nature to change their behavior or lure them to their deaths."
