I don't know what happened. I just feel that cockroaches now are several times bigger than before. I used to be able to kill them alone, but their current size is really, er... They should be a little bigger than a one-yuan coin! It's too terrible! What is onychomycosis! Yesterday when I was about to go to bed, I suddenly saw a big cockroach walking arrogantly in front of me! When I was hesitating what to use to hit it, it ran under my dressing table and disappeared completely! After a while, I actually saw an even bigger one crawling on my curtain! I was so scared that I couldn't sleep! Who can understand this terrible feeling? They are well-organized. My neighbor let me know the cockroaches, very cunning animals, which cannot be killed by any medicine! The stronger the medicine is now, the more super cockroaches are left according to the principle of natural selection!!! I think the only way is to make them extinct, but how?? Please give me some advice, experts!!!! Let's see the cockroaches die out.
