my night ends and I removed my mattress from my bed and I left it to the wall. After spraying, I washed all of my clothes and dried them very hot for more than 40 minutes. I forced to sleep on my couch and I left my bedroom closed shut for two more days to let a chemical treatment working to a full. After two days later, I found poor dead fly and another dead bedbug lying under my bed without a mattress. I still leave the floors unwashed for two more weeks to let a treatment working. By end of this month, I will start to mop my floors clean. So far, I have no problem! My landlord did a wonderful job!
