I've used the Raid home and garden spray for flying and crawling bugs, for years. It's a slender, green can.
One thing to do with ants is when you see their trail you'll want to erase it. The others know where to come in and travel buy the trail the scout ant uses. If you watch them they're usually in a line traveling. Wash the trail away and usually they'll find another entrance. and spray the area where they are coming in at.
Ants start being active again in spring and when it rains. Every time it rains their nest gets disturbed so they will travel to find another one. Or they are out hunting for food. If you even see even one carrying a tiny whie tube looking thing that means they're carrying a baby and looking for a new home, or found one, lol!
A large step to do is caulk. They are so tiny and you cannot see the tiniest of cracks they can come in through so use clear caulk, thin, in every area possible, like around windows, doors, floor boards, etc.
Now if there was a cure to rid the world of stink bugs I'd be thrilled!
**I wanted to add that you must keep counters and floors free of crumbs. Tiny crumbs may mean nothing to us but can feed an army of ants. Watch your trash can in the house too. Keep it clean and closed. Also, outside with your garbage or recycling cans. Don't leave open containers that attract ants. Rinse all recycling before putting it in the bins to keep down the ant and fly population. Rinse dishes directly after eating as well. Keep sinks rinsed and clean as well. The littlest of things can attract bugs.
