Sorry Reb Yidd, but you err. There is NOTHING cute about an infestation of ANY type. Spiders especially gross me out, yet I am the designated de facto spider-getter-rid-of-er. We once had an infestation of triangular shaped small flies in my shower. I had no idea where they were coming from, but they were there in copious numbers AND leaving larvae on the shower floor, whioh I discovered to my dismay.
Apparently it was something going on in other homes as well and whatever I tried did not work for nearly a year! Finally I got the brilliant to pour a gallon size bottle of Clorox down my shower drain. Never saw another one again. Liquid Plumber and Draino, btw, did NOT do the trick, prior to that.
I am literally TERRIFIED of roaches, and have rarely seen them in my house in 26 years kinehora (though our old apartment was another story entirely), but we have once in a shmitta seen HUGE weird looking beetles, bigger than Israeli jukes, almost the size of a mouse, and that sent me screaming for my husband (my son actually took care of it). I know HAshem has a purpose for ALL of His creatures, but just keep them away from me. PLEASE!
