Organic Pest Control in a Greenhouse

Aphids, Whiteflies, Sow bugs, centipedes, caterpillars, millipedes, mites, mealybugs, fruit flies and vinegar flies.

The two most effective methods of natural pest control we have used, before introducing beneficial insects are:

1). Pyola – a plant extract oil that controls the egg stages of pests present in dormant season and scale insects etc and also works on live insects such as aphids and whiteflies. The active ingredient is Canola Oil and Pyrethrins. The important thing about it is that it does not persist for long periods in the environment and does not contain Pheronly butoxide.

2). Diatomaceous earth, which is EPA approved and found at your local gardening shop, is fantastic for crawling insects such as sow bugs, millipedes, slugs, beetles and ants etc. It comes in powder form and like Pyola will destroy any beneficial insects so is best used before introducing them. Check the plastic liners in beds to see if this is where the bugs are coming from and if need be place the dust behind these.
