Your insects are not bugs, they are beetles. The pictures are not vey clear but this is what it looks like:  These are rose chafers... Macrodactylus subspinosis.  I cannot see what is in the product that you have but a pesticide that contains an active ingredient of cyfluthrin, carbaryl, imidacloprid, bifenthrin or permethrin should take care of them. Follow label directions.

These are purchased as concentrates and diluted in a pressurized sprayer.  In most cases, one or two sprays over a period of several weeks is all that is needed.
