Seek your opinion on the usage of methol crystal mixed with JWA for repellent specifically, here in south east asia, Malaysia specifically, the fruit fly is such a devastating problem, its impacting the yields and we can't commercialize it, seems that Garlic JHS is also may not be effective, what would you reckon?
I'm not sure because I haven't used menthol crystal. If you use it according to the 500ml standard, you can easily check the results. I think it would be effective to increase the amount of JWA and add caustic soda and fine clay powder.
