She had a key to the utility shed and an entire storage rack that was part of our agreement, as there is limited storage in the apartment. So I don't think she was being thoughtless. I didn't realize it was a black widow and didn't know we had those. I did try and remove the web and it was very aggressive and fast.
If it was on a fence I would just have left those alone. That would be part of the environment and ecosystem and easy to avoid.
I never use any chemicals with my vegetable garden. The wasps are beneficial insects, however they also like to make nest in the doorway corners so have to remove them. I just use a leaf blower to move them and remove the nest. They all die in the winter and the queen buries down in the ground for next year.
Anyway, I think we are on the same page here, the flyer and post are trying to inform and educate guest about insects and spiders.
As a host I have to do the best I can and can't always expect guest to be at the exact same place I am in regards to other living creatures on the planet.
I think this tenant was an insect lover but didn't want them inside. Its hard to tell which ones are poisonous. I think she likely brought the eggs with her belongings, though.
I used an embossing labelers for a note on the door lock to "Please keep doors closed. Mosquitoes." and have it in the house rules that leaving doors open will let in insects.
Always good to educate so great post. Some people are just really afraid of insects or spiders even if its dead.
