With the drop in insect populations that is being noticed world wide, indiscriminately zapping bugs is dangerous environmental policy. In an August 2019 interview, Day still maintains that the biggest threat from zappers is what he calls "non-target impression." The UV lights the gadgets use to lure mosquitoes in are additionally doubtless to draw plenty of different bugs.
