Chemical and organic control of glasshouse red spider mite

Insecticides should be used only as a last resort. Before application, ensure plants are receiving the appropriate cultural care and take steps to protect natural predators.

Organic controls like natural pyrethrum or plant oils provide some control of glasshouse red spider mite. These products have a short persistence so may need to be applied a number of times before the mite population is under control. Plant oils are less likely to affect larger, benefical insects like ladybirds and lacewings.

Glasshouse fumigants can be used in glasshouses. Seal the glasshouse and follow product instructions carefully.

Acetamiprid, a systemic neonicotinoid insecticide, is available for spider mite control. Follow label instructions carefully when using pesticides. Plants in flower should not be sprayed due to the danger insecticides pose to bees and other pollinating insects.
