While reroofing a house, I found that a foam cannon like this (https://cdn.protoolreviews.com/wp-content/uploads/2021/01/Chemical-Guys-Big-Mouth-Foam-Cannon08.jpg) filled with Dawn dish soap and attached to a 4 GPM / 4k PSI pressure is the perfect weapon for the little buggers. Unlimited cheap ammo supply, sprays a cone of fire 8 feet wide 30 feet out and the dish soap clogs their pores so they drop out of the air instantly like hit by lightning. Great practice for pigeon shoots!
