Parasitic Wasps

25 September 2019 | Diary

Friend Kristin has read my moth diary and she’s keen to tell me about a “natural” solution involving parasitic wasps.

Apparently you release the wasps at home and then seek out any unhatched moth eggs, feasting on them as the world’s grossest caviar.

Unleashing some wasps is immensely appealing, but I can’t help wonder if the situation wouldn’t get out of control. What, prey tell, will eat the wasps? Before you know it, you’ve entered an “old woman who swallowed a fly” situation and you now have a rather impractical horse infestation and you’re spending your evenings filling out the import forms on various apex predators. Your little West End flat becomes known as the spot where passersby are routinely plucked off the street by tentacles. We’d never get post again.

As it happens, the pheromone trap is doing rather well, our ten-moths-a-day murder count now reduced to one or even fewer. The trap now resembles a luscious moth-wing carpet, which I now plan to use to repair the various holes they’ve made in an act of mortal irony.
