Squirrel Wars 3: the further chronicles of

If you read  my last two blogs you will know the story of squirrel skirmishes one and two.  This is squirrel skirmish 3 and hopefully the last.  Yesterday, every time I opened the overhead door into the garage I would hear the squirrels stampeding in the attic... in a hurry to get out - where upon I would  bang on the  rafters  and cuss at 'em etc.. to help them along. The ceiling in the garage has drywall on it so I cannot actually see the little buggers...but I can hear them.  "Oh darn! They're still in there!" I thought to myself. Turns out, yes they did have an alternate escape route.  I originally thought they were entering through the louvres of the air vent in the gable and I was right...  but I guess they were only using that as an alternate route since the hole in the soffit was much easier... until I blocked it with a piece of sheet aluminium (see squirrel war 2).  I had put a piece of high density lattice over the vent  in the inside but that apparently wasn't enough- they just chewed right through the lattice and made a hole big enough to get out and then they'd go out through the vent louvers.
 So! I installed a piece of 3/8 inch plywood over the vent... again from the inside. That seems to have done the trick  'cause I haven't heard them all day and I have gone in three or four times.  But I am not claiming victory yet. I am not writing them off - they are determined little varmints. Maybe they will find another access point... we shall see.
