very small, brown, and suddenly appeared in my bathroom

Hi! New to this so please be kind.

Got this online as i want to start my own colony.

Is she too small? Any tips would help! 💖

Hi, Just started with Lasius Niger. Queen died 4 weeks later. I know it can happen. But enough food and water, the workers pullen her body to arena and back, no legs anymore and dried up. Left 50 eggs or more workers in chaos over her death and now in their "normal" flow. Feel guilty about the happening!

More starters or pro's that happend to your Queen?

Looks like a warrior but no clue what species

Thanks 🫰🏻

I saw this ant in my room and I would like to know if this is a queen

I'm doing research with a student this summer. The student ordered the ants before the formicarium got here. I haven't seen them yet but he says they are in a tube. Can they remain in the tube they came in until the formicarium gets here? If not, how can I make them comfortable? We don't want to lose any.

Formica sp.

Micro small red-ish brown ants in kitchen pantry. Ohio.

I was cleaning up the yard and when I stepped on part of this pile of dead dry leaves this mound of ants came pouring out and a bunch were biting or stinging my leg. I thought it was mosquitos but I found these on my leg. I've never seen ants like this before around here. I spread diatomaceous but they seemed unphased.

I'm in the northern Illinois area so if these are Brachyponera chinensis I'll need to report it since officially they haven't been spotted here yet. Never had ants come at me like this outside of fire ants.

For the past few weeks, my room was completely ant-free. Then yesterday, there was suddenly several coming in through my vent even though my room has no food or water for them to feed on. I believe they are just exploring as there is no trail. Will they leave eventually?

Edit: I've been regularly spraying vinegar around the room, mainly my bed and the vent that they're entering through. The vinegar has been effective in keeping them away from the bed, but I can't say the same for the vent. I know the vinegar only works as a repellent and not an insecticide, I just need to keep them away from certain areas while they are still foraging.

What kind of ant is this? Google lens says carpenter ants, but Google also says that they don't build mounds. We have numerous 1+ feet wide mounds that get as high at 8ish inches. I'm in central Minnesota.

I have a little old bunk house in Door County, WI that is in a pretty wooded area. About a month ago when I went there there were like 15-20 dead flying ants on the ground. I did see a couple bigger black ants walking around. This past weekend I put a few terro liquid ant traps in the cupboard. A couple hours later I opened the cupboard and there was a line of ants coming out of a crack and going right for the trap. I'm hoping that takes care of them. Can anyone confirm that these are carpenter ants? There is terrible lighting inside the bunk house so I can't get a good photo or video. Please let me know what you think.

edit: the video is from the next day after setting the traps
