I don’t know where, but bugs have started up in our office. It is impossible to leave unsealed food in the cabinet, on the table, ants immediately appear and begin to eat it. Just some kind of invasion. We turned to a commercial pest control service for help. It didn’t take much time to fix the problem, and it was safe to work in the office after finishing. But now I'm worried it will start again. Tell me, are there any measures to avoid insects?
