Guy Builds Cheap Mosquito Killing Machine [Video]
This seems like it might be good for "the camp."
If you've got an outdoor area, this may be something that you want to look into.
As he explains at the beginning, the mosquito man comes by and sprays for those little nuisances, but this could be something that you can add to it, and it won't break your bank.
Essentially, you take one of those auto-bathroom sprayers, and add raid to it instead.
He even goes so far as to put a bucket under the sprayer to show what was killed overnight.
Let us know if you try this out! We're wondering how well it works.
