Starting at about 3 weeks ago, I have noticed that there is an average of 1 to 3 worker deaths per day in my colony of 70 workers. I am sure they are not dying of old age. Some of the workers that died were young, lightly colored ones. They seem to just drop dead in various places and before they die, some walk all weird as if they're drunk and fall over and never get back up. I thought it might be their food, which used to be organic raw agar syrup and crickets, so I changed to feeding them honey and mealworms. Their brood pile is average for their colony size, and their population growth is around 1 worker per day.
Just FYI, this is my very first colony
Species: Tetramorium species E (now Tetramorium immigrans)
Colony Age: 11 months
Worker Count: ~70
Before 5/9/2018: small blob of organic raw blue agave syrup on a river stone, two ~10mm long crickets cut up, every other day
Current: small blob of raw unfiltered honey, two ~20mm long mealworms cut up.
Outworld: 5x5-inch plastic box with fine sterile sand, upper walls coated with Fluon
Nest: One 11x100mm glass test tube with cotton ball and distilled water inside
Temperature: ~75F day, ~65F night, no heating for nest
Humidity: not sure
I really, really hope there is something I can do to help them, but I don't know. Feel free to ask for more details
