I
forget what the Home Depot type stores "home name" for their product
that contains Imidacloprid are, but you may look at the true nurseries
for products of Merit II or Merit Wp or Marathon WP

Bayer advanced lawn and garden is the product that is commonly available. You
can also find it in dry formulation(meant for lawns) under various names.
Merit is a restricted use formulation of imidacloprid, it is not available to
homeowners. I still say hort oil would be a better choice for scale.
