Open the CIPO recordAbstract From the Canadian patent
A bait for controlling social insects such as termites comprises a cellulose material in finely divided form which is attractive as a food for the termites. Associated therewith is a second material having a significant delayed insecticidal effect on the termites. Thus insects directly contacting, and ingesting the bait will not be killed quickly but will distribute the bait within the colony by natural processes such as trophallaxis thereby eventually, killing a large number of insects. .
