Biological:

Biocontrol agents, like predatory mites, are effective as long as the correct species are applied rapidly and at the right concentration, which is usually achievable in most residential spaces. My favorite prophylactics for treating Broad Mites and several other pests, such as: the Hemp Russet Mite, Western Flower Thrips, and Silverleaf Whitefly, are the Swirkii Mite (Amblyseius swirskii) and Cucumeris Mite (Neoseiulus cucumeris). Both the Swirkii Mite and the Cucuermis Mite can subsist on pollen in the absence of prey, making them possible to establish continuously through the incorporation of banker plants or obtained plant pollen if applied regularly. You need to be careful when selecting which pollen to incorporate, however, as some species of plants can be toxic to these mites while also providing a food source for unwanted pests like the Western Flower Thrip.

Cultural:

Broad Mite presence that goes undiagnosed for even a single day can cause catastrophic losses, especially in late flower. Despite innate plant defenses, Broad Mites are unabated and can retard floral production to come while damaging preexisting floral production. In situations where prophylactic measures are not active, quick assessment of presence and utilization of treatments is essential for success because the mites can quickly spread and cause irreversible damage when feeding. Carefully removing colonized tissue or whole plants can reduce the spread significantly and make overall successful treatment of the cultivation space more likely. Keeping new Cannabis plants quarantined and limiting exposure of the current crop to the environment also helps to mitigate the chance for colonization. Importantly, Broad Mites are known to be phoretic – meaning that they use other organisms for transportation. One example is the Silverleaf Whitefly. Broad Mites are attracted to the wax the Whiteflies produce and will latch onto their bodies for hours at a time. For this reason, the prevention of the Silverleaf Whitefly is also a part of the overall prevention of Broad Mites.
