AMERICAN VANGUARD OF CALIFORNIA BEGINS EXCLUSIVE EVALUATION OF FSI’s MOSQUITO LARVICIDE

VICTORIA, B.C., July 12, 2006 – FLEXIBLE SOLUTIONS INTERNATIONAL, INC. (AMEX: FSI, FRANKFURT: FXT),a developer and manufacturer of biodegradable and environmentally safe water and energy conservation technology, as well as anti-scalant and crop nutrient enhancement products, today announces an exclusive evaluation agreement with chemical manufacturer American Vanguard Corporation with respect to FSI’s mosquito larvicide, WaterSavr-BTI™ (WS-BTI™).

WS-BTI is FSI’s proprietary formulation, which contains a self-spreading, mono-molecular film incorporating the natural insecticide ingredient Bacillus thuringiensis israelensis. This product was developed for the lucrative mosquito larvicide markets of the U.S., including mosquito abatement districts, government contracts and professional pest managers.

American Vanguard (NYSE:AVD) has agreed to expand on existing third party efficacy and application studies over the next five months and, in the event of a positive evaluation, will have the right to negotiate a distribution agreement with FSI.

American Vanguard is an industry leader in mosquito adulticides, but does not yet sell mosquito larvicides. They are enthusiastic about working with FSI and about the prospects of taking the WS-BTI product to market. Given the studies already completed, the non-toxic biodegradability qualities and the self-spreading ability of the WS-BTI formulation, FSI anticipates a considerable market opportunity.

FSI‘s research and development team is pleased to have the chance to prove our technology to a recognized leader in mosquito control. We welcome the opportunity to show how well our formulation works and we look forward to a successful association.
