Check out a company called GardensAlive. They sell pest control products and while some may be harmful to bees, the labels explain the best time and way to use the products.
For example, one product is only harmful to bees while it it wet; once it dries it is bee-safe. You could keep your hive closed during that time period (if you are the beekeeper) or cover the area with a garden fabric like Reemay if that's feasible until the product dries.
I usually stick to hand picking, but I am an old retired slug with time to kill.
That reminds me of when I was a kid and a man in the neighborhood paid the local children to hand pick Japanese Beetles, rewarding the 'winner' who collected the most beetles with $5 and all of us with ice cream.
