Stryker 54 could be used behind the siding if you are able to make direct contact with the wasps.
Stryker 54 is a contact kill only and will not leave any residual to continue to kill insects that contact a treated area. The only bees that will be affected are those you hit directly.
Stryker 54 does have an alcohol scent that will dissipate when dry and ventilated.
Stryker 54 can be used outside as directed on the product label for outdoor use.

Stryker 54 label lists spiders but not trantulas and there is no product we have found that actually lists them. If they are an issue in your area, we suggest speaking with your local department of agriculatural for a product recommendation.
