That's where I draw the line too. If they are disease carrying or destructive creatures I no longer have any compunction about calling Terminix. There was a time, even up about this time last year, when I opposed killing animals. My attic was invaded first by squirrels, then by raccoons trying to get the squirrels. The amount of damage they did came to over $2400. I had a professional come trap them and remove them. It's impossible to get rid of them d.i.y., and it's illegal to relocate them without a license.
Anyway, I told the trapper I did not want them killed. He said that is illegal here anyway. He has a license to relocate them. Then there were some mice. My cat caught one. Now, having changed thinking on a lot of things, I have no qualms about putting rodent poison for the mice, though I haven't seen any mouse activity for a while. Here's why... OK, I don't like glue or snap traps. Cage traps are a death sentence also, because if the mice are released into the woods, they will most likely die. Damned if you do and damned if you don't.
Now, what I do think is going too far is putting up with, and having to do end runs around, and change your life for animal pests. For example, I read once where a group of people would not destroy a hornet's nest that was right in their path of going in and out of a building. They preferred to do what they could to avoid the hornets and hoped they would move away by themselves. That does not fly with me... 1-800-TERMINIX all the way
Exactly my point... I don't go out of my way.
