The subject invention concerns novel biopesticides and their use to control cockroaches carpenter ants, and pharaoh ants. Specifically highly virulent isolates of Beauveria bassiana in an agricultural composition can be used to effectively control these pests. Exemplified are Beauveria bassiana No. 447, ATCC 20872 and Beauveria bassiana SP111, ATCC 74038. Also described are unique formulations which are highly effective for delivering biocontrol agents to target pests. By using these novel compositions target pests can be controlled, without the environmental and public safety hazards presented by chemical control agents.

Why it's free to use
- Filed March 21, 1995 and granted August 13, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 21, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 21, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
