 ===== Treatment ===== ===== Treatment =====
-  * ** Spinosad:**  +  * ** Spinosad:** If available in your area, Spinosad concentrates that do not contain soaps or oils is a top choice of treatment options. Tested and confirmed highly effective when used properly. Spinosad is food crop safe. Read and follow the label. Plants should be sprayed at dusk or lights out to prevent burns. Spinosad will affect insects that actively feed on your plants, so it will not kill eggs or pupae. Repeat applications 4-5 times, 4-5 days apart each to completely eradicate infestations. Spinosad works against most sucker class pests.  
-[work in progress]+  * ** Flying Skull Nuke Em:** This is an alternate product that is applied the same way as Spinosad, also food crop safe, but uses a different active ingredient - citric acid. Tested and confirmed also highly effective. This product works by essentially melting the insects on contact while the spray is wet. It theoretically works on all life stages, but eggs are often protected by being deep inside plant tissue, and pupae commonly in the soil, so repeat applications are still required. 
 +  * **Dinotefuran:** as found in Venom by Valent, is an effective treatment for Thrips and mealybugs. 
 +  * ** Natural Predators:** Releasing some beneficial natural predators into your grow space can be an effective method of control. Lacewings, Cucumeris mites (//Neoseiulus cucumeris//),Hypoaspis miles (//Stratiolaelaps scimitus//), and Nematodes are common choices that are highly effective. 
 +  * ** Beauveria bassiana:** This is the active ingredient in a range of products that act as a fungal attack on arthropods. Fungal spores will infect and kill the insects that touch the wet spray. Highly effective against all insects that touch the wet spray. Food crop safe. Requires 4-5 repeat applications 4-5 days apart. This product is NOT a top choice because it is a broad spectrum insecticide and will kill beneficials and pollinators, but it may be a good choice for indoor grows if top choice options are not available. 
 +  * ** Diatomaceous Earth (DE) & wettable sulphur:** DE an be mixed heavily into the soil or mixed 50/50 with sulphur to dust the plants. This is NOT a top choice because it is 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. 
 +  * ** Oils and soaps:** NOT RECOMENDED - Neem oil, horticultural oil, soaps, and products containing these are often recommended as treatments to various pests. Not only are they not as effective as the top choice treatments listed here, but also oils will block stomata pores, preventing plant transpiration and causing moisture blisters.
