Description

COMPOSITIONS OF VENBTOSO BAIT FIELD PE INVENTION The present invention relates to poisonous bait compositions that control pests, and methods for controlling pests.

BACKGROUND PE THE INVENTION The poisonous bait compositions are well known as they are useful for controlling pests such as cockroaches, ants and the like. Such poisonous bait compositions typically contain an edible composition that provides control over the pests after the pests have ingested the poisonous bait. Since the poisonous bait compositions also generally contain a pesticidal compound, there is typically greater pest control activity associated with the baits when large quantities of pests ingest the baits, and conversely, there is a smaller pest control activity when a plague swallows a smaller amount of baits. WO 91/9972 describes an insect bait comprising carrageenan as an insect attractant. The insect bait that is established in such ref. 29878 description, however, is deficient insofar as the insect bait does not control a sufficient quantity of pests when it is used to control pests.

BRIEF DESCRIPTION OF THE INVENTION The present invention provides a poisonous bait composition which can serve to effectively control large numbers of pests, including cockroaches, ants and the like. Specifically, such pests are placed under control after the poisonous bait composition has been used to control pests, based on the superior pest control activity of the poisonous bait. More specifically, by having a large number of pests that ingest effective amounts of the poisonous bait of the present invention, a pesticidally active ingredient in the poisonous bait results in superior activity for pest control with respect to the target pests. A poisonous bait of the present invention comprises: (1) a pesticidally active ingredient, (2) a carrageenan and (3) glycerin, and may additionally comprise optional ingredients such as fats, fatty oils, powdered crops, dextrin, sugars, synergists , other additive ingredients well known to those familiar in the art, and mixtures thereof.

The pesticidally active ingredient, the carrageenan and glycerin components of the poisonous bait compositions of the invention generally provide the poisonous bait compositions of the present invention or the ability to provide superior control over target pests, on which it is desired control. As such, the poisonous bait compositions of the present invention are also useful in enabling the inventor to provide an advantageous method for controlling these target pests.
