I'm out in the garden looking for that pile of jobby I found the other day, and it made me think back to my chat in episode 17 with Erica McAlister all about flies (and fleas).  Erica is the London Natural History Museum's expert on all things dipeteric (flies) and siphonapteric (fleas), and an extremely funny and nice person too. 

Reaching for that fly-killer? WAIT A MINUTE. Must we call kill all pests? (Must we even think of them as pests in the first place?)
