Why are modern people so afraid of cockroaches?

I think there are two reasons. Let me talk about it.

First, cockroaches are really terrible.

Why are many people afraid of cockroaches now? I think the main reason is that cockroaches are really scary. I think they are scary in two ways. On the one hand, their appearance is very scary, that is, animals with many feet look terrible. Moreover, because this animal's habit is to hide in the corner, we sometimes open the closet and suddenly see cockroaches. The sudden appearance of this thing is really scary.

Moreover, some of these cockroaches can fly and climb on food from time to time. As long as it is reminiscent of cockroaches crawling on food, it will make people feel terrible. Therefore, the scary appearance and sudden attack make cockroaches a nightmare for many modern people.

Second, modern people know too little about insects.

Why are modern people so afraid of cockroaches? A big reason is that modern people have been relatively far away from insects. In the past, people often approached insects because they lived in mountains and forests. Because they saw more insects, they felt less terrible. But now people are very hygienic, and even brush their teeth several times. And houses are generally clean and tidy. Modern people who are used to cleaning days, when they see insects like cockroaches, how can they not be greatly impacted? This is almost unprecedented.

So modern people are afraid of cockroaches. On the one hand, cockroaches are terrible, on the other hand, they are rare and strange.
