Try making bait out of table sugar and plain borax (found in the laundry detergent aisle). Mix it about 50/50 with just enough water to make a gooey paste and set it in very shallow lids wherever you see ants. If they don’t take the bait, add more sugar. If they keep coming, add a little more borax. I tried this solution two years ago and haven’t seen an ant ever since. Good luck!

Bedbugs?

try peppermint oil

Use a surface spray around the edge of the outside of your house, around each door and window frame. You might need to insect bomb every room to get the ones inside. Check absolutely everywhere in the house because it sounds like either you’ve missed something (any bits of food fallen behind the bed?) or there’s somewhere unexpected they’re getting in.

Sprinkle baking soda on your carpet and in your garbage cans. Little ******* hate it. Had an ant problem a few years ago and it worked for me.

every summer the ants cause a new hole in the concrete foundation of my house now and I find that bleaching the house from top to bottom (not just an expression, being literal) then putting a little bit of fresh ground cinnamon near the inside entrance of their holes and around their hills helps prevent them coming in for the summer

Sorry buddy, but those sound like lice, not ants

Ants don't like mint. Use mint oil, can put on cotton balls and line kitchen floor. I also know someone who used sticks of gum. It worked.

if you're getting multiple bites every night you might want to check your mattress thoroughly they may have set up a colony in or near it.

Ground Cinnamon also repels them and smells good as well. Get some ant bait stations, they'll eat it, take it back to the colony and it'll poison the queen. No queen, no ants
