Wormwood Pesticide Spray

Wormwood (aka Artemsia) is an old botanical plant with magical properties, not least of which is that it is a major ingredient in the psychadelic alcohol Absinthe.  The plants are toxic and can be planted as a companion plant to help keep aphids and fungal infections at bay.

A natural pesticide can also be easily brewed at home.  Simply take about 500g of wormwood, and put into a pan full of a couple of litres of boiled water.  Stir well and then bring the pot to a boil, leaving to simmer at boiling for about 8-10 minutes.  Turn off the heat and then let sit for half a day or so.  Drain the leaves out and decant the liquid into a sprayer, to use on your plants.

This is said to be effective against mites, insects, fungal infections, aphids, worms and larvae pests.  Best used on ornamental beds – don’t use on your edible crops.  

Of the many chemicals in wormwood one is thujone, which is a component of many commercial insecticides.
