It looks like Zap Guardian Canada will be easier to use and cleaner. There are no smoke, sticky mess, or strange chemicals to worry about. Plus, they make a big deal out of the fact that it's driven by the sun, so you don't have to deal with batteries all the time. Plus, this thing is made to be taken with you! You can use it on your backyard, in the woods, or anywhere else bugs bother you. That much variety is better than lamps and sprays that only do a few things.
