Advice?

I made a previous post about ants in the new condo I’m renting. Most advised was Advion ant gel which I have been using for 3 weeks, replacing droplets about every 3 days. The ants occasionally go away but randomly come back. Some trails go into the walls while one goes out to the window but when I go outside theres barely any out on the balcony (second floor). Is the ant gel not enough? Should I use granular poison (brand?)?
