"barmy" just means crazy, mad
"as barmy as a bedbug" is from Roald Dahl's "Matilda" and is just one of many examples of his use of animal imagery for comedic effect.
It doesn't mean anything in itself, no-one would actually say this, as no-one would describe bedbugs as being crazy, and they aren't a creature associated with madness ;) unless you go mad with how itchy the bites are - I got bitten all over staying in a hostel in Rome once and it took a week for the bites to stop itching, another week for them to fade....
It's the juxtaposition of the two items which never usually appear together (unusual collocation) as well as the alliteration of 'b' which makes the simile amusing.
Since it uses the comparative word "as" it is a simile.
Although there are other nicknames, the most common/household name for the bed bug is actually 'bedbug' (believe it or not).If you mean the scientific name, the scientific name for the bed bug is the Cimex lectularius.
