UpVoted #sawdah for an eye-catching post on Cockroach... I have seen a lot of Cockroaches in My country Malaysia. Then I went to Indiana State University USA, and the house I rented there during summer time there were many Cockroaches. These look to Me like a fully armored thick skin animal. I told My neighbor and she said, "Please do not spray on them, if you do the next summer there will look like indestructible military tankers."
