What is the evidence that Dichlorvos damages specimens when used
properly, i.e. not in contact with the object? Please give us
references. Has anybody tried any patent pet's flea collars or
control sprays?  Ipswich Museum used anoxic treatment in the past
(1989) found it very expensive and labour intensive to obtain
satisfying results.

Ipswich museum is not on the Net, I will pass on all messages from this
thread to Bob and Jeanette. Thank you.
