After a couple of weeks of constantly finding dead and not-so-dead wasps all over the house, I've finally discovered the motherlode in the loft. Actually it's a storage area under the eaves created when we had the loft converted so our bedroom is right next to it (and DS2's bedroom directly below). It is gross and although I know they will die off soon and they don't return to old nests, there are so many of the buggers flying/crawling around the house I know it's only a matter of time before one of us is stung.
So - who do I get in to get rid? Are Rentokil any good? Can I expect them to take the actual nest away or will they just puff in some powder?
