- How do I kill them? Preferably without using strong poison!

I would like to inform my poison for Diptera. (Originaly idea was Black's, from Black - to me, from me - to Ozerov, and Ozerov now use it!).
Woman's liquid for nails cleaning is 90% ethilacetat and 10% water. Ethilacetat rest insecta's legs ect easy moveable. The main profit of this liquid - nobody in airport tell you bring flameable liquid on board. Usual cosmetic!
