I know, I know, this is a pest species but I got the opportunity to get a colony so I took it. About a month ago, my dad got a little planter with a couple tropical plants in it. I quickly noticed before the planter were transferred into our garden that there were loads of little black ants walking all around the pot of plants. I realized these were L.humile, and since they are not present around my house yet, I was not going to let that change. I got permission to flood the pot, and the ants quickly evacuated onto the leaves above. I used my aspirator to suck up about 1,500 workers and 5 queens, and then sprayed the rest of the ants down with Raid and watered it into the soil to kill any remaining queens. So now I have a colony of Linepithema humile with five queens. :)

 

I decided that I would use two layers of fluon and a moat of dish soap-water to contain the colony. It took them about three days to get through both layers of fluon- one vertical layer and one upside down layer and they got to the soap-water. Well once they got to the soap-water they had a mas suicide, with about 100-200 workers jumping into the water and drowning. They got smarter than that after that, and stopped leaping into the death liquid.

 

As of now, the colony has 200-300 eggs, so they should make a full population recovery from the mass suicides in about a month. :o

Getting a recently caught colony to lay lots of eggs is one thing; finding an appropriate food they will continually eat and feed to the developing larvae is another thing completely, and will be the sole source of your frustration going forward.

Yeah, I am preparing for that. You can see some of their gasters are expanded in the images above- I am pretty sure that is Blue 100- which as of now seems to be their favorite food.

Well week after week I just kept losing workers and queens until now I only see like ten workers and no more queens. :( Oh well this was just an experiment anyway.

Yes, what you describe is a classic case with this species. I know for sure they need an infinite amount of water and heat, but a reliable food remains a complete mystery to me.
