avitrol corn chops
Avitrol corns chops is used as a frightening agent to remove pest birds from a given location, it is a chemically treated grain bait which acts on the central nervous system and the motor nervous system when ingested.
Thoroughly mix Avitrol Corn Chops with untreated corn chops, of the same composition, at the dilution ratios indicated below. For the control of Blackbirds, Grackles, Starlings and Cowbirds with Avitrol Corn Chops, do not use a dilution ratio less than one (1) part treated to five (5) parts untreated. House sparrows, however, usually operate within limited areas, with feeding and nesting sites relatively close to one another. Thus while ratios of one (1) part treated to nine (9) (or more) untreated parts have given good control in many instances, particularly stubborn cases may require a ratio of one (1) part treated to five (5) parts untreated.
You need to pre-bait before using the Avitrol corn chops, to avoid bait shyness. After the bird's feeding pattern is established through pre-baiting, replace untreated bait with diluted treated bait (one part of treated bait to five parts untreated bait)
