No , sorry I don't think the chems will atomize like that in the vapor. Kind of like distilling. Get a good little sprayer with the upturned nozzle. They work great for under sides of leaves. Azamax is a concentrate of neem oil and easy to work wit. Only thing we found to get rid of two-spotted spidermites.

Of coarse a doctor dooms bomb would do very good too and cover the way you want it to.
