Hate Mosquitoes?
I can spray about 1.5 acres in 90 minutes with this rig. We have an obscene number of mosquitoes here, so this has been a bit of an obsession for me. Treatments usually last about 3 to 4 weeks. The pieces for the current set-up cost about $40 in addition to your leaf blower. The poison I use is about $10/bottle, and 3 of those is good to keep 1.5 acres free of mosquitoes for the Summer. The linked video briefly shows the updates to the original set up. The link to a video showing that is in the description for this video.
$50 & you're free of mosquitoes for next Summer.
