I rent a 1-bedroom apartment on the 9th floor of a highrise. I've been trying to solve an ant problem over the past two months, including three bouts of commercial bait that is suppose to eradicate the colony. The problem only abates for a few days. The landlord has already brought in a pest control expert a week ago, who merely dabbed some gel at two spots (kitchen and bathroom). The problem remains unchanged, despite hieghtened vigilance in cleaning (I'm was already a clean freak beforehand). I may have to ask for fumigation. I believe that the landlord would be justified in inspecting neighbouring apartments, but that's not within my control.
From what I've researched online, an ant problem might be an ongoing management problem.
As a means of mitigating the problem, prior to actually getting it under control, would it be advisable to:
(1) Caulk up the junction between the baseboards and the wall, between the shoe moulding and the baseboard, and between the shoe moulding and the floor?
(2) Caulk up or re-caulk the junction between the kitchen counter and the wall, and between the washroom vanity and the wall?
My thinking is that restricting their mobility makes their life and survival more difficult, but I am also concerned that it may reduce the effectivenes of other measures. For example, it may interfere with their bringing bait back to the colony, or make satellite colonies more likely. Or it may impede fumigation, if that happens.
