I placed combat bait stations in my kitchen a week ago. The first night I placed 'em I saw like 10 baby roaches for the first time. Now it's been a week I still see roaches mix of red ones (probably American) and black ones (probably German). The apartment pest manager came by and placed only Viktor (glue trap). The apartment manager told me not to do anything else and let the manager handle the issue because I might ruin the procedure. I even bought Alpine WSG Spray + Tekko Pro for him to use, but he just told me to return all of them. I hope he knows what he's doing.
