I fear flying insects that sting, particularly wasps and
true hornets (genus
Vespa; some species commonly known as “hornets” are actually yellowjackets, genera
Vespula and
Dolichovespula). I don’t believe this fear is irrational, especially in the case of hornets, certain species of which carry some of the most toxic venom in the bug world and can kill humans (though this is, admittedly, relatively rare).
On nine separate occasions, we had a single hornet find its way into our home last summer. I will usually make an effort to escort wayward insects outside, but not in the case of hornets because they are too dangerous. They get angry easily and their stings are extremely painful—it’s not uncommon to pass out from the pain alone.
Bugs with these capabilities are rare (but YMMV depending upon where you live) and I don’t think it’s unreasonable to be afraid of them. On the other hand, they exist and if there’s a chance you’ll cross paths with them it would be wise to know how to handle the situation.
I strongly advise against attempting to kill a wasp or hornet by hitting it with a physical object. As has been pointed out, you could miss and anger it. Insecticide spray suitable for the bug in question and the environment (indoor vs. outdoor) works for us. It can be deployed from a safe distance.
If you find a nest, on the other hand, where I live that becomes a case for the professionals. We had to call one in to destroy a rather large wasps’ nest that had developed under the roof of our vacation home. The fire brigade will remove and destroy hornets’ nests for free, as this is considered to be a public safety issue. So know what options exist in your area and how to avail yourself of them in case of need.
For less harmful bugs like mosquitoes, well…not sure what to say about those. Wear bug repellent and the majority of them should stay away from you
