Broad Mites Cannabis Pest Control


Broad mites on cannabis plants are so tiny they are practically impossible to spot without magnification. Under a microscope, you’ll notice that young broad mites have six legs while adult mites have eight. Coloration can vary, but often they look like a pale yellow or clear dewdrop with tiny legs.

One of the biggest reasons broad mites can be so difficult to diagnose is you rarely see any signs of these bugs on cannabis, and you don’t see bites on the leaves. This is one of the main reasons why you need a complete broad mites cannabis pest control solution. The main way to spot an infestation is the damage they leave behind because usually broad mites themselves are too small to see. With a broad mite infestation, leaves turn up at the edges and may be blistered and wet-looking. New growth is usually twisted or drooping and if your cannabis plants are in the flowering stage, buds may turn brown and die.

Broad mites don’t attack all parts of cannabis plants evenly so symptoms may be worse in certain spots where the infestation is concentrated. Symptoms of broad mite infestation are commonly misdiagnosed and often confused for overwatering, heat stress, nutrient deficiency, or a pH imbalance. Unfortunately, broad mites are among the hardest cannabis pests to eradicate. To begin with, they lay their eggs inside the plant so it can be very daunting to kill those eggs with traditional pest control treatments!

Life Cycle of Broad Mites

(Picture above shows typical broad mite damage: wet-looking leaves that are  turned up at the edges, with drooping and twisted new growth.)

Life Cycle of Broad Mites

There are four stages in the life cycle of broad mites—egg, larva, nymph, and adult. Upon reaching adulthood, female broad mites lay four to five eggs daily on the undersides of cannabis leaves. Depending on the temperature, their reproductive phase lasts from 8 to 13 days after which they die. Female broad mites lay anywhere from 30-76 eggs in their lifetime. Adult male broad mites, on the other hand, have a significantly shorter life span of five to nine days.

It is interesting to note that unmated female broad mites lay eggs that hatch exclusively into males while mated females lay only one male egg for every four female eggs. Broad mite eggs hatch in two to three days after which larvae emerge to begin feeding. They don’t go quite far because broad mite larvae are slow moving. After another two to three days, larvae develop into dormant nymphs which attract males that pick and transport them to new leaf growths. These males immediately mate with females when the latter emerge from the quiescent stage. 

Organic Pest Control for Broad Mites

While maintaining a sanitary grow space is key to keeping broad mites away, there’s always a chance that you’ll run into an infestation during your grow cycles. Organic pest control methods against broad mites are your best options, considering that pest control and eradication procedures on cannabis are usually governed by safe standards and practices.

An organic pest control approach usually targets the disruption of the breeding and life cycle of broad mites. Pyrethrins do a great job killing broad mites on contact but must be used with caution because of their neurotoxin properties. Insecticidal soaps are recommended for spot treatments, but only when your cannabis plants have not reached their budding phase. Neem oil and capsicum have also demonstrated great results and bio-insecticides are equally effective at providing residual effects when taking down broad mites.

The introduction of beneficial insects to eradicate and control broad mites has also gained much popularity lately. In fact, the use of predatory bugs has become the first line of defense for many cannabis growers and hobbyists. Predator mites such as Amblyseius swirskii and Amblyseius californicus, for instance, have become quite valuable in cannabis cultivation as they gobble up both eggs and all life stages of broad mites.

Still, everything is dependent on the population of these specific bugs on marijuana plants and the effects of organic pest control methods on various life stages. That is why it is always best to consult with an organic pest control expert like Ryan at Ant & Garden Pest Control in Beaverton, Oregon to successfully eradicate or prevent a broad mite infestation in your cannabis operations.
