Ants in your bathroom is nothing compared to ants in your bedroom and all over your pillows at night while you're sleeping. And I say that because this reminds me of when we lived in an apartment back in Burleson, TX, and me and my older brother shared a tiny bedroom; so tiny in fact that we couldn't have anything besides the mattress of our beds in there. No drawers or anything. Anyways, randomly one night i felt like something was crawling on me and I managed to get the feeling away, when the next morning I noticed there are ants quite literally all over my pillows and in my bed. I'm not talking like dozens and dozens, maybe around like 15 or so, but when you get that much on your pillow and you were sleeping with them there, it's freaky. So I grabbed the vacuum, sucked them up, and found they were somehow coming in through the floor right under our closet (we had one of those sliding glass door ones). And this went on for days for some reason, when it eventually just stopped. I don't know how it happened or why, but it was creepy
I feel you. Not the same, but used to have a huge problem with ants in our kitchen, and, on occasion, our bedrooms.
I lived in Texas for maybe a year when I was a toddler. My two most prominent memories of Texas include ants. Once, my mom and I went somewhere and she didn't know I hadn't finished my sandwich, so I left it on the table to get back to later. When we got back home, there was a large black moving blob of ants where the sandwich had been. The second memory was me knowing that there was a box of graham crackers in the computer room, so I went on an expedition to get them. And the box was moving along the computer desk. I feel like my memories are playing tricks on me, I somehow doubt that the ants were actually carrying the box, but whatever it is that really happened impressed itself upon me until that was what I remembered. So yeah, ants.
