some products you can use. Go with organic methods first and try neem oil, pyrethrin-based insecticides, or insecticidal soaps.
If these don’t work, try some other broad-spectrum pesticides, such as neonicotinoids, organophosphates, and carbamates, that work amazingly against stink bugs. (1)
Or you can make your own insecticide by mixing half a pack of cigarettes and water. Filter the leaves, add some dish soap, pour it into a sprayer, and get to work.
Of course, large infestations still require the help of professionals, so don’t be afraid to call them
