    Question Spider Mites on Orchids. What am I doing wrong??

    I thought by now I wouldn't have much problems with spider mites that seem to love the hot and dry environment. One of my rooms have lots of light and it gets really hot, so I started using humidity trays everywhere in the house no matter what. I was watering every other week but since this year has been awfully hot, I started watering once a week leaving all my orchids in water from 30 minutes to one hour.
    If the medium stays humid too long you get fungus gnats and if it's dry you get spider mites! I just cannot get to a middle point! haha
    What can I do? I'm using neem oil and it seems to work well, but is it ok to use it on a regular basis to avoid the pest?
    Now, are they really spider mites? I cannot see them until I notice the damage on the leaves, and when I use a cotton swab with either rubbing alcohol or neem oil, something reddish comes out of them, like red/orange dust.
    Should I use a humidifier in the house? I have electronics everywhere, can they get damaged by the humidity? Pardon my ignorance!
    This thing is really annoying me to the point that I've been considering to get rid of lots of my orchids.
    Thank you all.

    u mean "if the media stays "moist" u get fungus gnats" yes u can use humidity trays and neem oil throughout but more importantly air circulation...keep a nice buoyant growing area...room shouldnt be stuffy....and the humidity shouldnt affect the fans,electronics etc.....also consider the type of media u use to grow ur chids and it sounds like u do hav a red spider mite problem...they have to be eradicated from ur entire growing area...new plants have to be quarantined before coming into ur house..also try new products that safe for plants...recently i used a spray can and spray plants and the whole area even the walls....Fendona is the product..its low toxicity to things other than bugs...and its highly residiual effects make it ideal...

    I grow my orchids everywhere in the house, all in front of the windows, and I use only bark mix. what kind of media are you using? If I use the product you're talking about I'm gonna need to spray the whole house! hahaha
    Thanks K. K.
