An insecticidal composition comprising:
- (a) about 1.0 wt. % to about 7.0 wt. % of a fatty acid including a branched or straight chain C5 to C11 fatty acid
- (b) about 1.0 wt. % to about 7.0 wt. % of a neutralizer including an alkali metal hydroxide, amine, alkanolamine, and mixtures thereof;
- (c) about 0.1 wt. % to about 1.0 wt. % of a buffer including citrate, citric acid and mixtures thereof;
- (d) at least about 80 wt. % of a carrier, wherein the composition has a pH of about 7.5 to about 9.0;
- and
- wherein the fatty acid and neutralizer form a fatty acid soap in an amount between about 5 wt. % and about 8 wt. %.
