Most garden pests die off over winter because it is cold and they can’t survive in freezing temperatures, but in the relatively comfortable environment of a greenhouse, any remaining pests will thrive. Slugs, aphids, red spider mite and mealy bugs all like to hibernate in hidden places inside a greenhouse. If you don’t eradicate them before spring, your newly sown seedlings will provide a tasty banquet for them to feast on. A deep clean will help you locate any sneaky slugs and other pests before they cause havoc when you start sowing seeds.
