Pharaoh Ants HELP

okay so my apartment building has had pharaoh ants for maybe 2 months now and the property manager had exterminators come twice (the first one was for the whole building and the second was just for our suite) weve been putting up notes to let the rest of the building know not to kill them, use vinegar etc because the propety manager doesnt like telling everyone important info like that and shes scrunched up all notes and thrown them out and the last one we put up she had put a sticky note that said "FYI the exterminator said they would be killed after the second treatment in 2-3 weeks" and after that we found our note torn up and in the trash so shes really out of the question. it has been much more than 2-3 weeks since the second treatment and so weve been doing our own method of using borax peanut butter and a little bit of water and for the first week they were going to all baits and throughout the week the numbers were becoming less and less, 10 in each bait down to 6, down to 3 etc and one bait only had 1 interested in it now its been about 5 days since refilling them and they all have 7-10 again and it feels like its not doing anything, im putting a teaspoon of borax and a little less than a teaspoon of peanut butter and then some drips of water to mix it all together and splitting the paste into each bottle cap. Any advice or help is greatly appreciated because the property manager doesnt care enough to do the proper measures

edited to say: we (and other tenants in the building) werent seeing any in our suite UNTIL the exterminator came and put some gel in the kitchen and bathroom
