I recently move to Illinois and move to a suburb that sits next to a man-made wetland. One thing I did notice is a large number of frogs that falls into the basement window cutout. I find one trapped once every couple of days. I usually catch them and release them back into the wetland.

I was wondering how I can prevent them falling into the grate? Can I use a finer mesh grate?

In addition, was it OK to release the frogs into the wetland? They seemed to be native in the area.

When I mow my lawn, how do I avoid running them over. They are so hard to spot.
