backpack fogger recommendation

[ironman_gq]

New house 11 acres, pretty sure I'm going to have a mesquito problem this summer. My yard is roughly an acre and sorrounded by trees and low wet areas. What backpack sprayer/fogger in your experience has the best reach to be able to get up into the trees. Willing to entertain all brands, we have Stihl and Husqvarna locally but I can order. I have lots of time using the Stihl SR450 and SR200 that I've borrowed, wondering if there is anything better than the SR450

The sr 450 works great

My SR400 is 25 years old and still runs great
