(Troutdale, OR)  --  Troutdale has a plan to use bats to combat mosquitoes.  The Parks Department will put three wooden bat boxes along Beavercreek Canyon at the edge of Kiku Park soon.  The idea is to create more habitat for nocturnal animals and cut down on the number of potentially disease-carrying mosquitoes in the area.  Some experts are warning this could be one of the worst mosquito seasons in years.
