I dont see any reason why roaches should be an issue. I used to live in the tropics where it does hapen that you get waken up by roaches trying to climb in the mouth and sucking on your saliva. It is a nice feeling if you get used to it
If you grow up with this then you know it is normal having insects in and around your house, if the population gets over the top you know where to buy pesticide.
I also wish there are not so many nonsense topics, is there anyone who wants to talk about the danger and high number of nazis living in Switzerland?
