I think this comic might be suggesting that they’re leaving the planet since it’s all used up and the worker is sitting there with nothing left on the planet as the rich flys off to another planet? I don’t think it’s specifically angry at space flight.

Oooh! Know what I’m playing this weeeknd! Thanks!

I’d say it’s more than just a bother. You’re spot on about preventing them from carrying and transmitting disease.

Though I’m perfectly okay not having bot flies around anymore… Another insect that could be considered a bother but we mostly destroyed their population.

Thanks for sharing! Tough to admit being tricked but helps us all stay on our toes.
