How to deter spiders and Asian beetles from entering my house?

We found that putting hedge balls in the basement (mine is old/damp) and also under the bed helped with keeping out spiders.

You can try this for spiders:

Peppermint oil soaked cotton balls for mice. I have also used a spray that is a 50/50 mix of peppermint oil & cinnamon oil that is very effective.

Hi Cj, I read somewhere to use salt water and spray areas on the outside of your house, porch etc. It is supposed to deter spiders. I am going to try it soon cause I have a bad problem that is growing worse on my porch.

Hi everyone, I have cleaned off the cobwebs and sprayed my porch with saltwater. I am going to wait a week or two and I will let you know if it worked.

Hi again, Well it has been a week and no new spider webs so I guess it does really work. I put my sprayer on stream because I didn't want it to go out into the grass. I wanted to keep it contained to my porch. It is raining so when the rain is over I plan to re-apply since it worked. Yay, no spiders while I am sitting on my porch.

Hi Rebecca,

That's wonderful news, congratulations on finding something that works for you!

I'll have to give this a try, myself!

Thanks for the update.

Here's a post that might help, there is a section that talks about using soap to get rid of mice https://chascrazycreations.com/irish-spring-soap-and-flies/
