On the Reasons for the Variation in the Effects of Formaldehyde as a Poison for House-flies
Published online by Cambridge University Press: 10 July 2009
Extract
The effective action of formaldehyde as a fly poison depends on the freedom of the exposed fluid from formic acid, and. to a less extent, from methylamine. That used for fly poisoning should therefore be colourless and free from a fishy odour, and a weak alkali, in slight excess, should be added in dilution to neutralise any acid present and that which will be formed during exposure.
