This was a fascinating episode. Thanks.

I wasn't aware that mosquitoes were particularly prevalent in the Netherlands. I sympathise with the allergy issue; I am also allergic to bites but thankfully not to UK species (yet), and I don't think there are many in Scotland (yet). I was also unaware that there are mosquito species in the UK which are potential disease vectors - just waiting for the diseases to arrive?

There's an urgent need for new action against mosquito-borne diseases. I was listening to a podcast about the worrying growth of mosquito resistance to bed nets treated with pyrethroid insecticides just the other day. The technology discussed here which allows particular mosquito species to be recognised by their sound is very impressive. I hope it provides the information needed to understand the problem and to improve control.
