Urethral Insect

Thank you very much. The explanation really helped me.

Ok, thank you, I've watched the video many times.

I want to try 20L Pesticide (soft water, 400mL JWA, 40g NaOH, 40g Clay) to deal with urethra bugs.

One more question, does the pesticide mixture not have a disinfectant effect on the soil? Or tips for safe use on the soil?

Please consider this solution. You can also cut the JWA in half.
