What does this mean?

what does this mean, "A serious problem is wasps."
Asked Jun 16, 2010
serious; I don't know this expression.
a serious problem is always something to be careful with, second: a wasp can sting and has also a thin middle. translate I see also 'crosspatch'.

my conclussion is: 'real problem can be nasty'.
