Bees, wasps or anything else that can sting you.
Roly-poly bugs. Innoccous little creatures that they are, they just wig. me. out. I like spiders, they’re cool and they serve a useful purpose. I dislike ticks, but I can deal with them. Most bugs I find inside just get put outdoors. But roly-poly bugs are just so grey and…EW.

Spiders, cicadas, grasshoppers.
But especially moths. I HATE moths. While butterflies are graceful and beautiful, moths are drab and they are chaotic when in flight. You never know where a moth is going to end up.
Any bugs that have navigational problems, they think flying up your nose or into your eye is the way to go.
True bugs (hemiptera), particularly shield bugs and stink bugs - it’s the grippy feet that icks me - the little bastards fall or land on you and you can’t shake them off.
And vespids - wasps and hornets, particularly yellowjackets(known simply as ‘wasps’ here) - they really are actually evil and anyone that says “Oh, if you leave them alone, they won’t harm you” is obviously in league with them.
Huh??? That isn’t a potato bug! That’s a Jerusalem cricket. This is a potato bug. (Actually, when I was a kid, we called pillbugs “potato bugs,” but we wuz wrong.)
I hate stink bugs. They’re nearly impossible to kill, and when you finally do… ew.
I’ve reached an agreement with the wasps in the attic. They don’t come out, and I don’t spray them with Windex and stomp on them.
The crickets in the basement are fine.

Also known as 'Potato Bug '.
That isn’t a potato bug! that’s a Colorado Beetle. 
Moths - they don’t actually gross me out, but all the mad swooping around the lights sort of disturbs me, especially as they just land on you without warning. Just before I posted this, a moth (hawkmoth of some sort, I think) with a spread wingspan of 4.5 inches just came in and flew around (I did the glass-and-postcard thing).
Snails…I think it’s they way they go crunch when you step on them by accident in your bare feet…<gag> <gag>, umm, I have to go puke now…
Potato bugs/jerusalem crickets are pretty much the ultimate in horror. They even smell terrible.
I have weird blend of revulsion and fascination when it comes to those things. Looking at them raises the hair on the back of my neck, but at the same time I’d like to have a little terranium full of the suckers and just stare at it for hours on end freaking myself out.
Bugs don’t really freak me out. I think most of them are pretty neat. Centipedes are pretty cool; the “wave” of the legs as they ambulate themselves makes me think of a Lewis Carroll type character, running frantically and not moving very fast. I even get cute music in my head.
That being said, I didn’t really know a lot about cicadas until the recent outbreak, and my wife (who spent time in Baltimore) was freaking out about them. We found a picture, and I said, “How big are they? There’s no reference in the picture.” She held up thumb and forefinger. I said: Wow. Okay, those are kinda icky. Plus she described how they fly heavily along and bang into your head like a walnut. That’s extra oogy, I concede. Then I said I’d read something describing the noise they make, saying the drone is something like a low whistle combined with a hum. “Is it something like this?” I said, licking my lips and producing the sound. My wife recoiled like she’d been shot, and said it was exactly the noise, and never ever do it again. 
But even with all of that, there is one buggy type thing that weirds the shit out of me and makes me want to claw off my own skin at the thought of getting one on me, or rather in me: the Guinea worm. Read, and shudder.
Scorpions. I hate the little buggers. Ate them once, in China, deep fried. Can’t stand them now.
junebugs and earwigs. junebugs and earwigs.
did i mention junebugs and earwigs?
Anything soft and squishy - earthworms, caterpillars, larvae. I know they’re completely harmless, but their creepy segmented bodies, the wave-like motion when they move, they way they sort of grope about blindly makes me want to scream.
Centipedes and milipedes are bad enough, but Japan has crazy mutant varieties. Here’s the lovely geji geji. The ones in my area, though, are grey-green and larger. They look so freaking alien. And the mukade. You haven’t experienced sheer terror until you’ve seen one of these thingsheading toward your bare foot.
Beetles and crickets and jointed things like that don’t bother me, but anything in huge groups is gross. I once had to cross a parking lot at night in Dallas that was totally covered with crickets. I couldn’t avoid stepping on them. I hate that crunchy sound! What’s worse, the crunching sound of them being squished by my car’s tires was audible even when I was in my car with the radio on.
Ticks and spiders (though not technically insects) freak me out. Spiders just have way too many legs and you just can’t trust which way they will go or how fast. I freak out if I walk into a spider web because I think the spider is on me. I used to have a brown recluse spider living in my garbage can and it would leap out when I took the lid off … too many legs and it leaps at you, that’s just wrong.
However, I do try to avoid killing spiders whenever possible and catch them and release them outside where they have a chance. I figure since they eat other bugs they deserve a chance … as long as they are not running at me or in my hair.
Ticks may be slow moving but a roly-poly engorged tick makes me want to gag. Accidentally squishing one is even worse. Before Frontline came along I had one heck of an infestation with my 4 long-haired dogs. I was almost ready to burn down my house to get rid of them.
Cockroaches (I do not call them Palmetto bugs, it sounds too nice), I hate them! They are gross, they do nasty things on your clean dishes. They always fly directly at you. Your cats try to play with them and bring them into bed with you where they run across you while you’re sleeping. If they crawl on you, you can feel their icky legs gripping you. shudder So you ask why do I live in Florida, home of some of the largest cockroaches in the world? I have no idea.
Cuterebra larvae - These are bot fly maggots. They are huge and spiky and sometimes you find them hiding in what appeared to be an innocent little wound on a cute widdle kitten. Then you unwittingly squeeze the area while trying to clean it and this monstrous maggot pops out like an alien. They are more commonly found on rabbits housed outdoors and rodents, but I’ve seen a few on cats. Though that kitten one still gives me the willies. You would not think a bug that size could have fit in that little hole on the tiny kitten’s head.
By the way, people can get these too, especially people traveling in South America.
Mole crickets - These probably wouldn’t bother me if one hadn’t burrowed into one of my brother’s knees while he was kneeling on the ground for a long time while working on his car. He didn’t feel it right away because his knees had gone numb. I get woozy just thinking about that.
Spiders.
I really, really hate spiders.
Which is not a good thing living in Australia & loving the outdoors. Unlike a lot of people snakes don’t worry me and you really don’t see that many (I think the spiders have eaten most of them).
But spiders…the Funnel-Web Spider is one of my personal nightmares.
I don’t live in or around their habitat but have run into them when in Sydney.
After seeing some of then in action I won’t go near them unless I’m carrying a shot-gun :eek: 
Spiders freak me out. It’s the way they move, with all those legs moving one after the other in a weird pattern. And then some of them move so goddamn fast that I have to throw my shoes ahead of them to hope to hit them.
But the absolute worst is the wasps. Or maybe they’re hornets. I’m not sure, and you’ll never see ME looking that up, with giant icky pictures, no sirree! They’re black and huge and have dangly legs that wave behind them as they fly around my porch and dive-bomb me.
Why did I read this thread before bed? Now I’ll have to inspect every inch of my bed in case something multi-legged is hiding there. And I’ll have to stuff earplugs in my ears in case something tries to crawl in to get warm.
Oh God. Screw it. I’m not sleeping. I’ll rock back and forth on a kitchen chair all night with a can of Raid and a shoe.
I am the girl who always picks up the earthworms that crawl blindly into the deadly sun and place them back into the grass. I am the one who refuses to let people squish spiders. The one who wanted to adopt praying mantids. So basically, I am better than most people with bugs. However, when it comes to cockroaches, my skin crawls. I won’t kill them, as I HATE killing anything and that crunch makes me shudder. However, going near them makes my skin crawl. Therefore, when I see a cockroach, I run, find a plastic jar and, staying as far away as possible, I gingerly reach out and drop it over the bug, then leap back, leaving insect and jar for my parents to deal with in the morning.
I came back to this thread because I wanted to recommend a short story called “The Cocoon” by John B. L. Goodwin to anyone who is afraid of moths. But on review I see that no one was actually afraid of moths, just irritated by them. Still, it’s a great, creepy story (and I like moths). It’s found in an old Alfred Hitchcock anthology called Stories for Late at Night. There’s another story in there that will give the arachnophobes the heebie-jeebies.
