FWIW, I find that so-called "insecticidal soaps" offer no advantage over
ordinary household liquid dishwashing detergents, and the same might be said
for horticultural oils compared to vegetable cooking oils.

My preferred spray for spot treatments is a tablespoon each of cooking oil
and liquid dishwashing soap (I use a brand made from 100% vegetable and
fruit oils) in a quart of water.

Ray, I've also used baby oil on a no ID Slc. applying it with a Q-Tip
to kill some kind of orange mite. I applied it to every leaf surface
(there are only 6) and down into the bract clasping the pseudobulb.
That also seems to have worked. I did wash the leaves with soapy
water a day or so later, because I was worried the oil wouldn't
evaporate and would suffocate my plant.
