I've used GardenSafe Fungicide 3 in 1....pretty good, Bayer Rose 3 in 1 systemic....pretty good and the best so far has been Organocide. The thing to remember is the plants will need at least 3 applications within a 10 day period....to kill off the life cycle of these beasts, eggs and all.
Good luck!

Sounds good too me! It depends if it's available in the Netherlands. Or else it will have to wait until I am back in France for christmas break... We could do a trade: Kelthane for KLN!

Erm, if the infestation is bad enough, wouldn't it be possibly advisable to repot them?
What's the set up like, I know that when the AC stopped working it appeared my 'chids were predisposed to getting mold...so I set up a fan to make sure that they got enough air flow. I grow indoors though.
I did notice buggies on one of my plants, but since it's been repotted and treated, it seems to be doing, ok.

About a life time ago, there was a product I believe was called Pentac which was fairly effective in controlling many of the mites. I doubt if you could find anyone today who still has any and if so, it might be too old to be effective. Talstar ,(bifinthrin), used to be labeled for control of mites but I'm not sure it is any longer (it really didn't work). I am not sure if malathion is effective on plant mites. It is used for the mites that get on various birds to good effect. Ironically, probably the most effective treatment is to use another mite for control! Once the plant mites are gone, the predatory mites will dissapear as they will not eat plants and thus starve to death. There are a number of predatory mites available from any number of biological control companies. The already made recommendations of the use of oil and insecticidal soap can also be used effectively. The mite population can really explode at high temps and low humidity. Some claim that an effective solution is to take the plants outside and just hose them off. I have not tried that but I guess it really sounds good!!

Biological control really works in commercial greenhouses. Not sure about the effects on individual plants in people's houses. There are 2 beneficial spider mites that eat spider mites. Phytoseiulus persimilis is a small red mite that looks like, well, a red spider mite! Amblyseius californicus is yellow- green in color, and has the advantage of being native in California and Florida! So keep a look out for this one. ( Sorry Cam, I don't think you'll see any in Cananda!  )

An old topic but I have questions about spider mites. I found webbing and mites on one ailing Oncidium/Odontoglossum (some sort of cross, NOID)
I bought it, un aware from severe root rot. One bulb with one root was left and it produced a new growth. It slowley is filling the pot with roots again. The new shoot looks good, a bit of pleated leafs but seem not affected by pests. The older leafs on the shriveled pseudobulb are infected.
I read that using soap/alcohol could help fight the infestation. I also read that Permetrhin is active against mites.
Is it stupid to think that a doggy shampoo with Permithrin (solution made in a spray bottle) may kill them too?
Humidity is pretty low now, I know a heigher level of humidty will help fighting these little buggers.
