The message .com
from "John Edgar" contains these words:

Put some poison in your roof space. That gets rid of them. You do not
ned the female giving birth up there, because the whole family will
keep coming back and they are extremely persistent. You need to kill
them all quickly. If you do not get rid of them, they will eat through
electric wiring. It all gets very expensive.

Squirrels in the roofspace are a well-known fire hazard for this reason.
In the event of a fire, and your insurance company finds out you haven't
made efforts to bar entry, you might find yourself in financial
difficulties to say the least.

My solution would be a marksman with a decent air rifle.

I can provide an excellent squirrel pie recipe...
