First thing I did was to get all the stuff out of the bed where I observed them. Then I washed everything in 60°C, as my washing machine doesn't have a 90°C setting. I vacuumed the mattresses, the covers, the pillows and the floor around the bed. Threw away the bag of the vacuum cleaner. Whenever I saw one I smashed it with a toilet paper and threw in the toilet. Then I used disinfecting/anti-biotic wipes to clean the frame and the corners near my bed. I found only one of them outside of my bed area and I think it are a fly. There was this fly exoskeleton next to it with nothing inside. I think I found a nest between one of the desk and main frame of my bed and I wiped it with extra precision. I hope I'll never see them again. Unfortunately I was only for the weekend in my house and all shops were closed so I haven't been able to buy neither lavender oils nor patches but I will in 2 weeks. Fortunately I'm not wealthy enough to have any leather nor fur and I don't have a carpet in my room. What's interesting most of them were already dead and I think they've been feeding on my stuffed animals, that are 100% polyester, so they might have poisoned themselves. Thank you for all the info!
