Yeah, the ants. Maybe they just followed a scent trail into your house and live far away. If that’s the case then it’ll be easy. A couple of addresses ago we had a fire ant colony living under our foundation. Nothing we did got rid of them. Even powerful poisons that they take back to the colony only worked for a week or two until the next round hatched and they were right back. It sucked! Best of luck! Hopefully they live far away.
Plus you’re stuck using your stupid laptop keyboard unless you want to lug a keyboard and mouse around. It’s really sucky for people who have carpal tunnel and need special mice and keyboards.
