For a scrog a bomb probably works, but natural predators would be better.
Just had my first spider mites infestation ever. Caught them early, sprayed with SMC, which is basically rapeseed/canolla oil. Cause the mites to suffocate, including larva. Does not kill eggs but prevents the from growing to adults. Does not cause resistance, can be used weekly. Similar to other "wash" products.
Pyrethrin, a flower extract, kills them by attacking their nervous system, causing them to go mad and stop eating and reproducing. Does not work on eggs, and spider mites (a population) can become resistant to it. Effective if used appropriately, which means spraying 3 times with 3 days apart. It takes 3-4 days for the eggs (like stalkless amber trichs on the bottom of leaves) to hatchs, so the idea is to kill those new ones before they become adults and lay new eggs.
Cold temps and high humidity slows them down significantly. They also use the photoperiod to determine when fall is coming, they are less active with 13 hours of light per day. This does not kill them and can cause them to go dormant for the winter.
If they are or became resistant to pyrethrin or other products, there are products specifically for resistant mites. I got bioquant ivermec-res as backup but not sure if that's available in the US.
Probably the best way to kill the adults, larva, AND eggs, especially in a scrog and during flower, is to use natural predators. They suck them dry in all stages. Best is usually Phytoseiulus persimilis, depends on the mites, another is Neoseiulus californicus. Some require higher humidity than others. Forgot the link/site but there are suppliers in the US that send out cocktails of three different predators for less $ than most products. The predators will eat each other once they cannot find any mites anymore.
Good luck killing these disgusting suckers. Before you start your next run, Lysol your growspace else you risk getting them again the next time you run too hot and dry.
Hey Sativied , i copied this from another site,, is this what your talking about,, sorry its so long
pasted ::"::::Apparently the popular De-wormer Ivermectin is extremely effective against spider mites.
Has anyone tried this???
A brief intro, please bear with me guys-
A couple of years ago I used an ivermectin horse de-wormer to treat my dog when she had scabies. I f---ed up though and gave her the dose for about a 600lb horse by accident. The dog lived, didn't get sick at all, and all the mites digging under her skin died within a day or two.
Then, today I saw on ***** where a guy had treated his spider mite infestation with a spray made from ivermectin bird miticide and water, it killed all of the mites and none of the plants- apollo 13 I believe. Then I looked more and found the same treatment on an orchid forum for Two spotted spider mites. Then it made sense to me, the scabies on my dog were MITES- slowly, and somewhat dimmly the light bulb came on inside my brain... Sometimes I hate being on the slow side.
For those who don't know: Ivermectin is a very popular horse,cattle, pig, sheep, bird, cat and dog de-wormer. You give it to your dogs when you give them heart guard. It is used on humans too, sold as Stromectol®. It also is certain death for most types of paracitic mites, including the ones that cause mange in cats and dogs. Chemically it is related to avermectin B which I believe is the main ingredient to Plant Vitality Plus, a proven kill all for mites (feel free to correct me if I'm wrong). I found out more about the where it came from and uses of it, but I don't want to bore you all.
Ivermectin can be bought as an oral jel for horses, or in a topical or injectable liquid for cattle, sheep or pigs and such at your local feed and farm supply store, Tractor Supply Company, Southern States, or online from most horse or farm catalogs, valleyvet.com for example. IT's about 15 bucks for 250ml of pour on de-wormer. and the cheap Ivermectin Gel goes for about $2.50. The dosage is 1ml per 22lbs of bodyweight for the pour on, and one tube treats a 1200lb horse with the gel.
I have not tried it yet. and I don't know what ratio to mix it at. THe gel wormer seems the most likely candidate simply because of it's price, and the fact that the one dose should treat a s---load of plants. I am going to give this a shot and post my results, but I wanted to know what the peanut gallery had to say, as well as share my "discovery" with the rest of you all.
HAS ANYONE TRIED THIS HERE???
What kind of ratio of Ivermectin to water should I use?
I'm just saying... this stuff is a helluva lot cheaper than most spider mite remedies out there, and is said to kill em dead, without the bug bombs and other such madness.
