Probably. I simply go ahead and use the malathion 55% since it is available locally and I know that I will not have to re-treat the same pot twice. But, with fewer orchids, and growing indoors, you are probably good to go with the mix you plan to use. Since I grow in a greenhouse - not attached to my home, I can use stronger chemicals without the same difficulty as growers have who grow in their homes.
