Almost any insecticide will work in this situation. Most professionals prefer dust because they have more "lasting" power or residual effectiveness. The other benefit is that they "flow" with air movement into voids and also "disperse" much more effectively than aerosols.
The only thing you need to apply dusts is a good hand duster. The Puffer Duster is the most popular. Simply fill about 1/3 full of dust, and then "puff" the dust into the areas where the insects are located. In some cases, you may need to drill holes to get the dust into the right areas.
Wasps in soffits can be difficult to control. Applying an aerosol overhead is a problem in itself. In this situation, a dust would almost certainly work better, although an aerosol would give faster results.
The best advice I can give is to consider using a dust and a Puffer Duster, since there is nothing that any hardware store sells that would "inject" the insecticide into this area. Most over the counter wasp sprays are designed to be sprayed directly onto the nest. They will work, but you have to have direct contact.
Dust into the areas where you see the wasps going in and out. Also, if possible, remove the soffit covers and also dust into the open eave if possible. After dusting the entry points, seal them with caulk or a sealant. This should eliminate the wasps living in the soffit.
Hope this helps.
