Spidex (Phytoseiulus persimilis), Spical (Neoseiulus californicus), or a combination of the two are highly versatile and effective in almost all situations. Phytoseiulus persimilis, found in Spidex Vital, Spidex Red, and Spidex Boost, is a type 1 specialized predator mite adapted to hunting in heavy webbing. It also has the highest numeric response to spider mites. Unlike other predatory mites, Phytoseiulus persimilis does not require specialized plant hairs to lay eggs on, so it can reproduce on plants like cannabis or many ornamentals that lack these hairs.
