The "one-way squirrel excluder" arrived yesterday. I am certain that the squirrels have vacated the attic as the spikey ball I placed in the access hole last Tuesday has not moved, and we haven't heard any noises from the attic. It has been too hot the past couple of days, and I have been dealing with a stomach virus, so I haven't been in the attic yet to confirm that they have left, but I am 99.9% thinking they are gone.
I will probably just keep the "excluder" just in case we have this issue again.
The little picture of the house and squirrel made me laugh.
