An insect barrier

With reference to figure 1, the present invention provides a crawling insect barrier (1) comprising a cover member (3) and at least one receptacle (5) for retaining an insecticidal bait, the at least one receptacle being disposed on an inner surface of the cover member in a manner so as to allow insect access to the bait when said barrier is located at least proximate to a passage which provides insect access to an area, wherein the crawling insect barrier is capable of substantially preventing the access of an insect into an area from a passage when the barrier is placed over the passage. The barrier is preferably also adapted to allow water to pass therethrough and, into, for a example, a drain.
