My brother in law and father in law and I joined up and bought a back pack blower with 3 gallon tank on top. WE get insecticide from the local JD dealer in a concentrate. I go through the woods, in the yard, bushes etc and spray every 4-6 weeks depending on weather. For at least 4 of the 6 weeks no bugs. Then if it rains, they come back. last night they were coming out thick so time to get spraying again.
The spray is very cheap, the equipment more expensive. Certainly it would be touch to spray 5 acres, or even 30 acres.
My brother rigged up a gas powered power washer on a trailer with the intake hose that is designed to suck in soap to suck insecticide. Some how he is pumping water into the power washer from a 55 gallon barrel in a utility trailer. He drives around the woods and yard until the 55 gallons are gone but can really throw the spray with that rig. Or maybe the 55 gallon barrel has the premixed spray in it, not sure but it works for bigger properties that way.
I don't spray the pond area and I'm sure there are a few less bugs for the fish to eat but that isn't their main diet anyway.
