Abstract: A device and method for controlling ectoparasites on agricultural livestock is disclosed which gives improved long term application of a pesticidal composition directly to the most frequently infested areas on the livestock. The pesticidal device hereof comprises an elongated, flexible, synthetic resin carrier strip which includes an incorporated volatile or non-volatile pesticide. An attachment is provided for fastening the device in cantilever fashion from an appendage of or an object worn by the animal, or to a portion of an animal confinement area, so as to assure that the device comes into repeated or continuing contact with adjacent portions of the animal's body. The device is advantageously of a length for free swinging movement thereof in response to the natural movement of the animal, thereby releasing the incorporated pesticidal composition from the device for direct application to a relatively large portion of the animal's body.

Abstract: Compounds of the formula ##STR1## in which R.sub.1 is a lower alkyl, lower haloalkyl or lower alkenyl group, R.sub.2 is hydrogen, halogen, lower alkoxy, lower alkyl, cyano, or a nitro group, and n is an integer between 1 and 5, R.sub.2 being the same or different when n is greater than 1; and their use in controlling pests, e.g. acarids, fungi, helminths and protozoa which cause coccidiosis.
