Abstract: Hydramethylnon gel bait (Infinity®) 2% w/w was evaluated as an insecticide agent against American cockroach (Periplaneta americana L.) and German cockroach (Blattella germanica L.) in 3 university canteens, Mahasarakham University, Thailand. The bait was reduced >99% of cockroach trap counts in all sites after 1 week post-treatment with the only single treatment. Then, the reduction rate of all test sites was further sustained up to 4 weeks in the post-treatment. The American cockroach trap count was reduced significantly at the 1st week of the post-treatment to the 4th week of the post-treatment (>99%). Nevertheless, the reduction of >70% was sustained from 5 weeks up to 10 weeks for the post-treatment. A minimum reduction of 52.38% shown at the twelfth week of the post-treatment. For the German cockroach trap count was reduced significantly gradually over 99% also at the first week to the 6th week of the post-treatment. However, a reduction of over 70% was sustained from 7 weeks up to 12 weeks in the post-treatment. A minimum reduction of 61.90% shown at the 12th week of the post-treatment.
