Yuk!
I hate bugs.
I live in the desert not many mosquitos here, we have tarantulas.
Tarantulas!!
They aren't as bad as you might think. They are huge among spiders and are mildly poisonous but not deadly. And they won't bite unless provoked. If you are gentle you can safely hold them in your hand. (So I've been told. I haven't actually done that and probably won't.) A lot of people keep them as pets.
I had a friend who had one as a pet. *shudder* I'll pass!
I have one that lives in my front yard. He keeps the bugs down around the front porch.
He's black and white, a very unusal color from the rest who are tan and dark brown.
Tarantula Facts
We don't kill or remove every daddy longleg spider we see in the house either for the same reason. They don't make huge webs and they are harmless to humans, but if they are around, we don't have to worry about getting any bad spiders in the house. So I can appreciate you having a 'guard' tarantula on your place. I wouldn't bother him/her either. For the same reason when we lived out on the mountain, we cautioned our house guests not to kill the couple of king snakes that lived somewhere close to the house. They are harmless to humans but deadly to any rattlesnake that happened to venture onto the property.
The highway from I-40 to Santa Fe that goes along the east side of our mountain--our road to town when we lived out there--is two lane traveling through really rugged country. I often drove it when we were still working as I worked in Santa Fe quite a bit.
One day I was headed to Santa Fe when I pulled over to watch a tarantula migration that happens now and then. Thousands of tarantulas all moving together across the highway. An amazing thing to see. And I was a bit amused to see how many people in vehicles will swerve to avoid hitting a spider.
