title: Effectiveness of methoprene-impregnated baits in the control of Monomorium pharaonis ant populations infesting health establishment and households.
abstract: The use of baits consisting of dried egg yolks and impregnated with 0.5% of methoprene, loosely applied twice within 8-12 days at the rate of 1 g of bait per 3-6 m2 of floor surface area at each application was found to result consequently in a complete eradication of M. pharaonis ant populations in two medium-size health establishments and in one apartment house. Under more favorable conditions in another health establishment the use of methoprene-impregnated baits applied twice at the average dose of 1 g per as many as 46 m2 floor area proved equally effective in ensuring permanent eradication of ants. Providing that all colonies on the premises can be affected by bait a complete eradication of ants can be expected within 100 days after the first application of bait.
