On the positive side,
I did find this natural killer/preventive spray
that is made from household products, you may already have handy!
Natural spider killer or preventer…
take one cup of vinegar, one cup of pepper, a teaspoon of oil and liquid soap.
Put it into a spray bottle and spray along the outside of your home,
front door and along windows; refresh after it rains.
I’m definitely going to give this a try!
