I've only ever seen 3 roaches in here since October. The first was about a month after I moved in, and it was in the dishwasher. The other 2 were yesterday and today. Someone told me the heat brings them in, and I'm thinking that might be it because nothing has changed, cleanliness-wise, in my apartment. I did just check my cabinets and got rid of some paper bags as a preventative measure. If I could find my roll of packing tape I'd seal the gap under the door. I'm going to ask the office tomorrow if they have any recommendations.
