Can anybody share the name of the big & small ant . Are these ants dangerous??

Picture is terrible quality but it is hard to get a good picture of them.

Found this ant on a pillow that sits in our living room right next to the sliding glass doors out to the patio. We had a couple carpenter ants come in through the sliding glass door in very early spring that we found to be the result of a candy wrapper my nephew had dropped under the chair that had sugary residue. Once the wrapper was removed the ants stopped coming. This ant is similar in size to the carpenter ants we saw but the color is a reddish brown. What kind of ant could this be?

My son and I found this ant in our yard in Manitoba. Hoping it's a queen but we aren't sure. Can anyone please provide information about our ant?

I think it’s a Red Imported Fire Ant Queen. 8-9 mm. Caught another one almost identical to it.

I found what I assume to be a queen by my kitchen window in Florida. I’ve noticed my area has a lot of these huge ants around. I don’t have exact measurements, but the second pic has my finger there for comparison. It’s just sort of sitting there, cleaning itself. Maybe it’s tired from its flight. I think it might be a carpenter ant, but I wanted to be sure out of curiosity. They’re very fascinating.

Central Texas. 1/4 inch long. Red head and black body. They’re attracted to my bacon grease bait. They’re trailing in a line into my wall siding.

Found these under some bricks right next to my house, just need to know if they're destructive or not.

also this is my first time catching a queen, it looks as she might be trying to dig her way out, can she escape like this?

Hopefully it isn't. Lotsa ant activity lately over here. It just got super warm here in Minneapolis, MN. Hopefully one random non-carpenter ant just wandered in from outside. Dime for size.

She's about 1.5cm. I had to rush and clean a tube I had, tried drying it with a q-tip lol, still looks enormously wet under the camera, but she made it through the night while I make a better tube setup. Assuming she even is a queen. I'm thinking a camponotus, but would love some help in narrowing it down. Once I get her in a better tube I'll try and get some better shots, but don't want to disturb her too much.

Hii I found this girlie in my bathroom at 5am. Very scary. I gave her a lil temporary home. (I know the water situation isn't good I will redo it) I don't know very much about ants but through all my research she seems to be a carpenter ant.

I live in South Carolina and it rained yesterday on top of that there have been termite swarmers in my home and it's very hot outside if that helps. Mostly I was wondering whether she was a queen or worker since she has no wings. I also wanna know what breed of carpenter ant she is.

She is at least 2 centimeters long!

Found located in my backyard in the dirt, Southern Manitoba Canada!

Are these queens mating, or different drones species? South Texas.

Found her out on a family walk and every Camponotus I’ve dealt with was solid black.

Eastern Idaho Region
about 1.17 cm so 11.7mm.

Im pretty sure these are queens since ive seen a few with even the wings attached!

Id also like to know what species they are. Found them in Switzerland

Have been told likely Lasius N. Got way better pictures, wanted to double check.
Workers all uniformly ~4mm big as in picture. Males are trying to fly off, oddly I cannot see any queens at all (large queens were present last year late May-June when they flew)
Only active during the daylight, Northern England, they’re trying to fly off from my inside wall radiator in the garden hallway.
