[Nhcoll-l] [EXTERN] Clean Boxes in Pest Infested Room

[Fabian Neisskenwirth]

Hey Julian,

Dirk is right. Specially because eggs of some of these best are very 
hard to find. They just wait for a ideal conditions for hatching. This 
can take several month without noticing, and suddenly you get the 
unexpected pest again. Freezing (two times, with at least a week in 
between freezing's) is the only certain way to go. There is always the 
anoxia treatment with nitrogen as a very efficient alternative.

All the best!
