There are several methods for controlling spider mites in a garden:
Biological control: This involves using predators such as ladybugs, lacewings, and predatory mites to eat the spider mites.
Horticultural oil or insecticidal soap: These can be used to smother the mites, but must be applied directly to the pest and must be reapplied after rain or irrigation.
Neem oil: This is a natural pesticide that can be used to control spider mites.
Keep plants healthy: Spider mites thrive in dry, hot environments, so keeping the garden well-watered and maintaining healthy plants can help prevent infestations.
Keep the area clean: Keep the area free of debris, leaves, and pruned branches that can provide a breeding ground for spider mites.
Avoid over-watering: This can cause the humidity to increase, which can lead to an increase in spider mite population.
It is important to note that it is best to use a combination of these methods for the most effective control.
