Hello ? By the way, question for those who have encountered it. We bought an orchid today, everything is beautiful, nothing suspicious. Came home, found a small cockroach. I shook all the earth with the orchid in the toilet and washed it off, I washed the orchid from head to toe. So what's the probability that there will be cockroaches? What can you do for prevention?
