Advice on applying miticides

[carykeshen]

Hello All - This is my first post on this forum.

I grew orchids about 25 years ago, got busy with work and raising kids, so my interest petered out, but now I'm retired and doing it again.

I have purchased a number of plants recently and have noticed some spider mites. Don't want to see this get out of control so I just ordered some Avid and some Forbid 4F that I will use in rotation.

My question is: Should I start off with one of them for several treatments and see what level of control I get and then just switch to the other? Well, how would any of you approach mites? I tried Neem oil on a couple of plants, but it just does not seem to be effective.

Thanks in advance.
