Lanai drainage holes
 

Has anyone had any experience with drainage holes being drilled on their screened in lanai? Who does that type of work? Is it worthwhile or does it serve as a conduit for little furry creatures (not coyotes) or things that slither to enter the lanai? Thanks

My very effective, fast and free method was to back off on the two or three screws holding the aluminum channel to the concrete at the deepest point of the puddle. Then put something that won't rust like plastic or a coin beneath the channel to raise it slightly off the floor in just that area, then tighten back down. Did that a year and a half ago works great and no critters get in.

any nasty bugs crawl under?
