Aspic lienal experiment makes clear, in 0 7 ℃ the low temperature to 0 8 ℃ issues aspic lienal 5 ～ 6 hours, can exterminate all mew bug egg, larval, aurelian. Accordingly, microtherm weather is the favorable opportunity with lienal aspic. Particular way is: Every afterwards box puts 8 ～ 9 lienal, stagger fold put in the cold wind outdoor to invade place, one day and night can.
The experience with airtight old suffocating makes clear 2 vulcanization carbon, use 2 vulcanization carbon airtight suffocating, the egg that can kill mew insect, larval, aurelian with imago. Via one-time processing, if do not have exterior mew bug to invade, won't again mew bug eat by moth feeds mew lienal. Using the specific method with lienal mew of suffocating of 2 vulcanization carbon is: 6 afterwards box is every 5 ～ to be folded, every afterwards box puts 8 ～ 9 lienal, put into what use make it of new plastic film, inside the large bag that ties one end, uppermost ministry puts containers esp. for use in the house of a dish of state, among them the solution of 2 vulcanization carbon that 200 milliliter control infuse (by every afterwards box 4 milliliter of 3 ～ are calculated) plunge into polybag able to read aloud fluently to be become namely next. Operation personnel attention is not inspiratory 2 vulcanization carbon.
