Greeting All,
Has anyone, information on the use of methanal (formaldehyde) HCOH as a mite
treatment?
Following Bob H's logic ..........
"The chemical formula for vinegar is CH3-COOH very similar to formic acid
which is HCOOH. Do we know the way formic acid kills varroa and tracheal
mites?" .....
Methanal (formaldehyde, or formalin) is much more user friendly and
certainly kills bugs.

Cheers Paul b. ...doesn't seem to improve a head cold though...

On Behalf Of Bob & Liz
