You must be very cautious with any new chemical treatment. Orchids are sufficiently different from other plants for it to be unsafe to make assumptions.
Older growers will remember Malathion which is a superb bug killer, and maybe harmless with sympodial orchids but fatal to some monopodials, in particular phalaenopsis - it caused the growing point to turn into a flower bud, so that the treated plant never grew another leaf...
And then there was the infamous Benlate - cured fungal infections, but killed so many young orchids that du Pont ended up with 7 figure payouts ( not to me or you, of course, but to the big producers of orchid seedlings ). and tge effects became visible only some time after absorption into the plant tissues, making it diffucult to pin-point as the cause.
So beware using the new wonder mass murderer of all pests until it has been tested, and trsted again and time has passed...
Personally with rather more than hundreds of orchids of very many kinds and genera, I find mass treatments expensive and unsatisfactory. Spot treatment - when I see a pest I stop what I. Am doing to deal with it - and for most things a quick spray with alcohol/warer 50-50, and mabe a sweep with a clean artists paint brush kept on every bench for the purpose, to get the stuff unto the nooks and crannies and sweep away any debris or eggs/nymphs. If is is scale, then the Neem mix instead, but actually, the alcohol works with them too to some extent.
