    Default Systemic for mites?

    I am fighting a losing battle with mites. I sprayed my orchids eight weeks in a row with a product containing both insecticidal soap and pyrethrins. A couple months later, and I've found more mites.

    Does anyone know of a systemic that both works on mites and is safe to use indoors? Thanks in advance for any info because the mites must die!!!

    I think I may have mites too. Are they pin-point dots on the leaves and pseudobulbs? I keep wiping them off with rubbing alcohol and tho they are stubborn I haave control of them

    I find a spray bottle with some dishsoap and rubbing alcohol does great...if they are quite bad you will notice white stuff on your potting mix. That means it's time to repot and treat the entire plant thoroughly. They like to hide in your potting stuff.

    I have not seen any white stuff in the potting mix, but it would not surprise me if some are living there. They are obviously hiding out somewhere!

    Increasing humidity also tends to make things less hospitable for the little pests . They don't tend to like moisture much.

    Thank you. I'm sure the humidity could use a boost, especially this time of year. I'll try to improve on that.

    Raising humidity is a very good defense for mites.

    It does however take the joy out of knowing that you personally killed them with some type of insecticide.

    There is a product called floramite, but I don't know if it's rated for indoor use, or approved for use in NY.

    True, and fully roflable. Mites do love a dry plant -- seeing them is usually a sign to me that I'm underwatering. And as satisfying as it is to poison the little suckers, they'll keep coming back as long as your orchid seems like a fun place for them to hang out. After two months of soap and pyrethrins, I'd definitely think it's time to look at your care regimen for the plant, and, as other people said, the potting medium, because that should have done them in by now if it was going to.

    There are sveral systemics that orchids can take. GO to your local supplier ( even a big box). I use Bayers rose special ( fertilizer/systemic fungicide and insecticide in one liguid) or the version for trees and shrubs. follow the dosing instructions on the packages....These contain what's called Merit ( works on scale also)
    Typically anything with acephate should do the job. Just soak the roots in it outside... put the pot in a bucket to apply it, or something like a bucket to isolate it....a disposable plastic bag? NOt saying to leave it outside or leave it in the bag...

    The Bayer with Merit alone won't kill the mites. It is a good insecticide unfortunately mites are arachnids and the Merit (imacloprid) may actually trigger faster reproduction in mites. Look for Bayer 3 in One complete insect disease and mite control. 2 teaspons per pint. Or find something labeled specifically for mites.
