When I was a kid I was super scared of insects, but I blame that on my mom who raised me like that. When we came back to Canada (and much smaller spiders and such) I decided I was tired of being scared of spiders and bees and I shock therapy myself! I let a spider crawl on my arm, realized I was not getting bit, no harm, realized people are freaking out for nothing (no poisonous spiders here). Same with bees I was actually petting them while they were busy doing bee stuff on clover flowers. Even helped a bee with my hands to go back outside, if you are relaxed and calm movement the bee is not getting scared and sting. I even picked up a tarantula at a Christmas zoo fair for the kids, she snuggled in my hand it was amazing, I was so terrified of them when I was young! Really happy I got over bug fear that my mom stupidly raise me with.
And that is what I taught my kid who is growing up never being scared of insects. He laugh at his school mates if a bee or a spider is in the class and helps the teacher getting it back outside. Don't squish a bug in my house my son will be all over you before I even say a word. He's a real tree hugger too, always was since he's little.
For the mosquitoes and roaches: I'll try to get them out/blow them off me if they are a loner but don't invade my place! Never happened to me but a cockroache infestation is super unhealthy for humans so I would not tolerate them inside.
