Were this some sort of behavioral or environmental trigger that affects a person's daily life I'd be in agreement here but we are discussing a videogame creature the size of a baker's dozen daisy-chained go-karts, inside of a videogame that does not otherwise have a focus on invertebrates.
Lethal Company had a spider filter, Satisfactory had a spider filter, and System Shock 2 had a spider filter (mod) for pretty much the exact same reason; both spooky and non-spooky games with isolated and fairly common severe phobic response triggers. EDF does not have an ant filter that I'm aware of for equally obvious reasons. I'm not going to say it's something the VotV dev should be obligated to fulfill, but it's not an unreasonable option to bring awareness to and leave on the table, and it doesn't need to be shouted down by people advocating for extensive psychotherapy for the express purpose of being able to play a goddamn videogame.
