[OGD] We're going buggy

[Peter Hirsch]

Can anyone help us eradicate a tiny (fraction of a millimeter) black 
beetle that is infesting our greenhouse?  To the naked eye they look 
like large grains of soot.  They appear beetle-like under a jeweler's 
loop.  Sevin seems to kill colonies that appear on flower buds, but they 
reappear on the next plant with buds.  There is no clear sign that they 
do damage, but they're certainly not an enhancement to beauty.
Peter and Marie
