Abstract
Abstract Cattle and other livestock are protected from insects such as face flies, horn flies, ticks and the like by use of a uniquely effective insect control device attached to the animal. The insect control device comprises a polymeric resin matrix, preferably in the form of an ear tag or ear band, containing a liquid, insecticidally-active isomer of alpha-cyano-3-phenoxy-benzyl-alpha-isopropyl-4-chlorophenyl acetate.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
46 words
An insect control device for attachment to cattle or other livestock comprising: (a) a polymeric resin matrix having dispersed therein an insectically effective amount of a liquid, insecticidally-active isomer of alpha-cyano-3-phenoxybenzyl-alpha-isopropyl-4-chlorophenyl acetate, and (b) an attachment means for affixing said polymeric resin matrix to said animal.
Claim 2
Dependent Claim
46 words
An insect control device for attachment to cattle or other livestock comprising: (a) a polymeric resin matrix having dispersed therein an insectically effective amount of a liquid, insecticidally-active isomer of alpha-cyano-3-phenoxybenzyl-alpha-isopropyl-4-chlorophenyl acetate, and (b) an attachment means for affixing said polymeric resin matrix to said animal.
Claim 3
Dependent Claim
