This is my go-to bug spray. Be warned that it's greasy (and apply after sunblock). It works great. If it holds up in the Amazon Rainforest, it's good to go.

These ant baits work great to stop ants from taking over your surfaces. They're pretty effective in my experience.

Want to eliminate an ant or roach on site? This spray will do it the trick. Works great in tandem with the ant bait traps, but I don't recommend spraying the spray where you think the ants are entering your dwelling.
