How to get rid of ants:
Take the queen ant hostage and crucify her upon your console for all the ants to see. This will likely cause an outrage in the ant kingdom and will result in retaliation. They will likely try to inflict pain upon you via biting you, but you can bait them.
Place a delicious sandwich in your car. The leaders of the ant army will see this as a good opportunity to wage a war of attrition by cutting off your food supply.
You must set this up as a trap. Inside the sandwich will be many high-power firecrackers. You will rig the sandwich IED to explode via remote detonation.
Find a good place to observe the sandwich from afar using binoculars. Wait until the sandwich is fully saturated with the ant army, then detonate the IED.
Initial casualties will be devastating. The leadership of the ant army will realize the trap they've sprung and will begin retreating.
Using thermal technology, you will observe the leadership element exit the vehicle with a security element.
Ambush the security element using an aerosol spray and a lighter. Let the Ant Army leaders watch as their soldiers burn. At this point, they will have no choice but to surrender or die.
Take the ant leaders as prisoners, interrogate them, find out more about nearby ant armies, perhaps turn them into spies to corrupt other ant colonies, but do whatever you can to land a crushing blow against the ants.
