Spider mite question - on cacti
Posted 07 November 2010 - 11:06 AM
I got some trichocereus cacti this summer. I noticed some of them had brown spots on them. I was thinking this was maybe some old healed up damageds caused by rot or something. The brown spots are randomly spread all over the cactis, not at the top.
But yesterday i noticed some REALLY TINY small red creatures. Maybe as small as 0.1mm. If i stare at them i can't see them move, but if i remember where some of the tiny small creatures stood and then leave for 10 minutes and come back, i can see that they have moved a wery short distance. The infistation isn't that bad, but they are defenately spread all over the cactis.
Does this sound like red spider mites? They move really slow and i can't see anything that looks like silk/webbing.
I have sprayed the cactis with tobacco and greensoap watersolution today and washed the pots and windowsill. Hopefully it will help.
Below is a picture of the brown spots, does this look like spider mite damage?

unless you notice the spots increasing I would'nt worry about it.
The skin on trichs is very sensitive and does'nt react to well to most pesticides, expecially oil based ones.
what you used seems like a good choice, however if you do spray wipe it off very shortly after so the skin does'nt absorb it. That and it's a good idea to just spray a very small part first to see how the cacti reacts before soaking the whole thing:horse:.
Hope all goes well for you!

Found a spraycan in the garage with a remedy that is supposed to kill them. Gonna spray one cacti with it first to see if it doesn't harm it.

And got a 40 year old peyote now and some 10-20 year old ones, gonna post some pics soon :)
Spidermite Controll is oil based btw, but it says its all natural plant oil. Every tricho and lopho i used the remedee on half a year ago doesn't seem to have taken any damage what so ever :) I recomend this product.

As recommended above, I was suggest spraying with a diluted neem oil.

mullein and marigolds in a spray bottle w/ water.
*non-sponsor link removed*
mullein is an antibacterial agent and repels many insects and animals.
marigolds also repels insects and mosquitoes.

I dont get any webbing at all and not totally sure what the damage they do is, nor what kinda mites they are. Did let them stay on some of my little yoteseedlings for a while and i think they started to shrivle up so i dont dare to just let them be. To live right beside the forest brings with it some ups and downs.
