Q:  Birds have taken up residence in my house at the roof overhang.  The entrance hole is now large enough to invite squirrels and rodents into the roof and attic.  What can I do to evict the birds without harming them?  D.N., Plano.

A: Try spraying the birds with hot pepper tea or Lemon Joy soap.  It will not hurt them long term, but the temporary injury from the oil in their feathers will encourage them to find another place to mess up.
