Predatory Mites (Phytoseiulus persimilis) offer a safe, biological control for damaging Spider Mites in your garden. Spider Mites are amongst the most damaging pests of roses, fruit trees, vegetables and many common garden plants. Populations start to build up in spring and then rapidly increase during the hot, dry weather over the summer months.
Spider Mites are sap sucking pests. First symptoms of Spider Mite attack is usually faint, white speckling or spotting on upper leaf surfaces. As populations build up, they can often be seen as silvery, grey-brown patches on the undersides of leaf surfaces. Severe infestations can seriously stunt plant growth and leaves can be sucked dry to the point where full or partial leaf drop can occur.
Predatory Mites attack and eat most species of Spider Mites including damaging Red Spider Mites also known as Two Spotted Mites (TSM). Once Predatory Mites are releases they quietly work away, helping restore a natural balance and keeping Spider Mite populations under control. Spring is the optimum time to release Predatory Mites, as the predators will help control Spider Mite populations as they naturally build up.
