Can Spidermites destroy the bud?

If possible raise humidity, they don't care for that too much. Since your near the end of harvest I wouldn't bring it past 45%. With two weeks left, I wouldn't worry too much, other than maybe smoking a few dead mites you shouldn't have a problem. Just clean down the grow area VERY well, throw out used medium, and maybe bomb the grow area is possible. Those little bastards are a pain to wipe out and I have had a few battles so far with the. No Pest strips are the only thing that truly wiped the little bastards out. But I don't care for having them around me while in my grow area. But I wouldn't sweat it to much p, two weeks won't wipe everything out. If you really feel you need too, a little vacuum with a small amount of suction can help keep them at bay for the mean time. Good luck and happy growing.

I'd hit them with a pyrethrum bomb and if it kills the adults, keep hitting them every couple days. This stuff will not kill the eggs so repeat treatments will be necessary. Try not to bomb for about 4 days before harvesting and the pyrethrum should be gone by then. It breaks down quickly. Works on many varieties of mites, but not all. Good luck! Hate those fuckers...

Im callin you out on this one for bad info. You drop a bomb that late into flower and ya might as well suck a plutonium rod popsicle. Dont bomb that late......ever. Id remove all tainted leaves. Run a vacuum over them to get rid of clingers and cut a week early.

Pretty sure its organiic and safe.

So, what's the big deal?
While pyrethroids may be amongst the least toxic of insecticides, they are an excitatory nerve poison, acting upon the sodium ion channels in nerve cell membranes:
by sending a train of impulses rather than a single one, they overload the pathways, blocking the passage of sodium ions across cell membranes; similar in action to organophosphates (which include the now banned DDT); inhibits ATPase, which affects the release of acetylcholine, monoamine oxidase-A and acetylcholine;
inhibits GABAa receptors, resulting in convulsions and excitability (and more 'minor' problems such as sleep disorders);
known to be carcinogenic;
liver damage
thyroid function
cause chromosomal abnormalities in mice and hamsters;
are highly toxic to insects, fish, and birds;
mimic estrogen, leading to estrogen dominant health problems in females and feminizing effects in males, including lowered sperm counts and abnormal breast development;
sublethal doses have produced a wide array of abnormal behaviors, including aggression, and disruption in learning and learned behaviors



What are the pyrethroids?
Pyrethrin is one of two liquid esters derived from Pyrethrum (feverfew) (C21H28O3 or C22H28O5) that are used as insecticides. Pyrethrum, a nonvolatile hydrocarbon related to kerosene, is a similar insecticide derived from and chrysanthemum flowers.
The fact that they are derived from plants causes some people to think - a point played up by companies using this toxin in their products - that they are safe. Lots of plants are toxic, some in small quantities, others in large. Just because it comes from something lush and ornamental does not mean it can't be lethal. Oleander, azalea, mistletoe, and foxglove are just a few of the pretty - and highly toxic - plants with which we live.
Permethrin is a synthetic pyrethrin (C21H20Cl2O3). In other words, it is a man-made poison that is a copy of two poisons found in plants.

Thirty bucks aint spendy when fighting mites.

Well im certainly no expert.
I guess I was just going with the fact
that if you arrive at the hydro store
with late stage mites.
That is what they are gonna recomend.

I can go with what you said as it being
less toxic.

Personally at this stage I would use mechanical removal with temp and humidity as a control.

Reason being the dead mites and their shit and eggs are already in there
and will be even if you throw money at it
via a fogger.

However when the crop is done
I would nuke the room back to
the stone age.

I remember running behind the fogger
truck in texas with my little friends
in the early 70S so im not the best one
to talk safety.
I think that shit was ddt.

Try isopropyl alcohol watered down to about 30/40 %
kills em on contact does not hurt your plant, I know someone
who uses 70% but that scares me a little, probably ok but my
concentration works and I'm comfy with that.
you can do it with watered down eucalyptus oil
but about 1/100 ratio makes your plants stink but it kills em
straight away as well! Pyrethrum two weeks out and a flush in between
shouldn't hurt anything as it breaks down within a week but I'd rather use less toxic methods anyway.

Just to clarify he has buds with trichomes.
Are you ok with him spraying alcohol
on the buds or are talking about wiping leaf surface?

Just wipe the underside of the leaves..don't spray anything this late if you have to tho only use sm 90! All this advice is quite funny your Buds are practically done just wipe everyday with a towel soaked on some type of insect killer...

I've never sprayed with buds but I don't see it hurting than as it evaps in minutes

It disolves on contact.
Cant say ive done it.
I have made iso hash though
thats what makes me think its a bad idea

They are going to dig into the buds and eat them all up

Hope that helps Oh did I say that I needed some rep?

yes, given enough time they will destroy the bud itself. i saw it happen last fall with some of my outdoor crop. i had to leave it hanging untrimmed for a couple weeks while i took an emergency trip to help out family. i got back and it was all deteriorated, not recognizable as bud anymore. luckily, it was all early harvested crap that i ended chucking out anyway.

listen to the people here who advise caution, you don't want to be spraying with anything other than water at this point and will liekly want to harvest/salvage early, get what you can before the mites do.

Some people try using a vacuum, very gently. I will agree with everyone here, dont spray this late. Maybe try lady bugs? I have heard thats a good way to combat them. I am fortunate to be able to find hundreds of them huddled together in spots at work, but i have heard you can order them online.

With vacuum there is a risk of too much suction as you can't set the amount of suction or air flow given out by the machinery.
