I'm with Nar, I never kill bee's if I can help it. I don't like them, but they have a purpose. Wasps, on the other hand, need to be killed if they come near me.
We had such an incident the other week. My partner was home from work late and had bought some sushi for dinner. We were sat on the sofa munching away when the cat started staring up at us. He said "Aww, she can smell the fish". I happened to glance out of the corner of my eye..."OH NO SHE CAN'T, she's eye-ing up that f*cking HUGE wasp that's buzzing around your head!". This was in the middle of January! Thankfully, the cat jumped on it and killed it - I just had to vacuum up what was left of it.
We suspect that it was a queen wasp that had been disturbed from it's hibernation when we turned the heating up. Queen's are the only wasps alive at this time of year and should be hibernating.
Now...spiders.
As a child, I was TERRIFIED of spiders. My mother would always get the vacuum on them. I've gotten braver as I've got older and can now put a glass over them and put them outside, but if they're particularly big or if they're running around a lot, the vacuum comes out.
