 ===== Symptoms & Identification ===== ===== Symptoms & Identification =====
-Spider mites can be tricky to distinguish from beneficial mites or tiny spiders, which are also beneficial. If you see fine webbing, very close to the plant tissue and spines, with numerous stationary or very slow moving mites on it, this is a strong sign of spider mites. Spiders are often solitary unless they are very young, and beneficial mites do not produce webbing and move significantly quicker. Over time, their feeding damage can lead to secondary issues, such as rust infections, which present as dark spots near the base or other areas of the plant. +Spider mites can be tricky to distinguish from predatory mites or tiny spiders, which are beneficial. If you see numerous stationary or slow moving mites on it, some of which suspended a small distance off of the plant with nearly invisible webbing, this is a strong sign of spider mites. They congregate near tips, in crevices between ribs and in with spines. Spider mites can be white, white with a black dot on each side, orange, or red. Spiders (the non mite type) are often solitary unless they are very young, and beneficial mites do not produce webbing and move significantly quicker. Over time, their feeding damage can lead to secondary issues, such as rust infections.
  
 When identifying mites, growers should observe their movement speed to distinguish pests from beneficial predatory mites: When identifying mites, growers should observe their movement speed to distinguish pests from beneficial predatory mites:
-  * **Pest Mites:** Move slowly relative to their leg size and tend to settle in one spot to feed on plant sap. Very small, nearly invisible to the naked eye.+  * **Pest Mites:** Move slowly, small enough to be nearly invisible to the naked eye, nearly invisible webbing may be present.
   * **Predatory Mites:** Beneficial. Move noticeably faster as they actively hunt for prey. Larger, though still tiny. Easily visible with the naked eye.   * **Predatory Mites:** Beneficial.

 ===== Treatment & Management ===== ===== Treatment & Management =====
-  * **Water Spray:** Hosing the mites off the plant is a good initial step to reduce their numbers. A strong blast from the hose across all of your columns tips on occasion is a good preventative for many tiny pests. +  * **Water Spray:** Hosing the mites off the plant is a good initial step to reduce their numbers. A strong direct blast from the hose to your columns tips on occasion is a good preventative for many tiny pests. 
-  * **Spinosad (e.g., Captain Jack's Dead Bug):** Recommended as a highly effective spray specifically designed to target and kill mites. This is a top choice treatment method if you have access. Get the concentrate version of the product, avoid soaps and oils, follow directions closely. Must apply at dusk/lights out, and must apply 4-5 times, 4-5 days apart each, to break the pest life cycle. +  * **Spinosad (e.g., Captain Jack's Dead Bug):** Spider mites are known to build resistance to spinosad within a few generations. If it's all you have on hand it can greatly cut their numbers for a week or two, but long term they will multiply and an alternate treatment will most likely be necessary. Apply at dusk/lights out, apply 4-5 times at intervals based on life cycle - evey 3 days in warmer weather up to every 7 days in cooler weather.  
-  * **Azamax:** Alternate effective miticide option. Possible side effects include phytosensitivity.+  * **Flying Skull Nuke Em:** Food safe alternative to spinosad. Citric acid based. Apply just like spinosad, but mites will not build resistance to it. Using it and spinosad alternating from early treatment is highly effective. Product can be difficult or impossible to get in some localities. 
 +  * **Azamax:** Alternate effective miticide option. Possible side effects to plants include phytosensitivity.
   * **Diatomaceous Earth (DE) & wettable sulphur:** DE an be mixed heavily into the soil or mixed 50/50 with sulphur to dust the plants. *Caution:* non-selective and will harm beneficial insects and pollinators. Additionally, growers must wear a mask when handling to avoid inhaling the dust, which is hazardous to the lungs. Dusting will damage farina and permanently alter plant skin appearance.   * **Diatomaceous Earth (DE) & wettable sulphur:** DE an be mixed heavily into the soil or mixed 50/50 with sulphur to dust the plants. *Caution:* non-selective and will harm beneficial insects and pollinators.

-Introducing predatory mites is a highly effective natural control method: +Introducing predatory mites is a highly effective natural control method including *Amblyseius californicus* or *Phytoseiulus persimilis*, depending on your local climate.
-  * **For Foliar/Red Spider Mites:** Introduce *Amblyseius californicus* or *Phytoseiulus persimilis*, depending on your local climate. +
-  * **For Soil Pests:** Soil-dwelling predatory mites like *Stratiolaelaps scimitus* (also known as *Hypoaspis miles*) are beneficial for soil health but will not target red spider mites on the upper plant body.+
