A new method of using ethyl acetate mixed with candle wax has pretty well revolutionized parts of collecting here in Finland. The use of other toxics (poisons) is no longer motivated.

You melt about 2 centiliters of wax in a glass jar which is in a bed of nearly boiling water. Then add 1 – 1,5 dl ethyl acetate and mould  any little container with a surface area of about 150- 200 square centimeters to have a long lasting kill-effect inside a trap.

You can use a jar moulded with this soap-like ethyl acetate for weeks as your killing- jar without needing to fill any ethyl acetate. I’ve mixed 4 centiliters of wax with 3 dl ethyl acetate and molded it to the bottom of a plastic jelly-jar , surface some 150 square centimeters and about 2 cm thick, and this kills in a trap-size container weeks !!

After some trial-errow here we have the best results with using a ratio  7 to 8 parts wax mixed with 100 parts ethyl acetate . I measured my own mixing and it’s 7 and a half cubic centimeters of candle wax to 100 cubic centimeters of ethyl acetate.

The figures in my first post are wrong. Sorry.

Hi.

…., but certainly this invention makes both trapping and using killing jars much easier.

A WWW page with some instructions and pictures of the preparation of ethyl acetate wax is visible at
