I lived in an old farm house years ago...laundry was in basement (nothing else)...one day noticed a daddy long legs spider in a Web above washer...the next thing I know there are gobs of baby spiders there...I let them live...they were so cute...course if they went outside the sprays for the orchard likely killed them.
My house is an almost 300 year old log house.
*Totally* not sealed, at all.
Everything wanders in, at some point.
I never have to “decorate” for Halloween.
;D
