Description: Camponotus pennsylvanicus is a massive black carpenter ant located in many states throughout the United States.  They are large in size and grow slowly during their first or two before rapid growth is achieved. Growing colonies can be quite ravenous for protein and a constant supply of nectar. They are quite active during the day and really love nectar. They are an aboreal species, often found nesting in trees and tending aphids for their sweet honeydew.

Development: Swarming from March to June

Foundation: Set in a cloister (without food) Development: 50 - 60 days from egg to worker (depending on temperature)

Size of the colony: Mature colonies can have 10,000+ workers and the queen can reach the age of 15 - 18 years or more in some cases.

Tips: Fluon is recommended as a barrier to help contain your growing colony. Provide a warm spot within the nest for the colony to choose the best temperature to speed up their brood’s growth. Always provide humidity in one of area of the nest and a dry area nearest to the heated area to establish a gradient for your ants to choose what’s best for them. Since they typically choose cavities within live or dead oak trees, they do no require quite as much humidity in the nest as other species and can actually be housed in wooden nest (like we sell) without an internal source of humidity as long as water is offered to them in their outworld.  They do not start having brood development issues until humidity reaches a constant 20%-28%  This species loves fruit flies more than any other insect, when it comes to protein and but will frequently accept, dubia roaches, small crickets, and small spiders as well.  It is always best practice to cut up larger insects so your ants can access the protein within. They are also quite fond of byFormica Sunburst Ant Nectar and a constant supply is recommended. As a matter of fact, all of our ant colonies here at Ants Emporium are raised exclusively on byFormica Sunburst Ant Nectar so don’t forget to add a bottle to your cart! A byFormica liquid feeder is also recommended to provide a steady source of carbohydrates to your ants without having to disturb your colony on a regular basis. Hibernation is recommended with this species. Start the hibernation process when you start seeing your workers huddling together, slowing down general activity, and when they appear to be “fat” with a swollen gastor. The workers and queen appear fat because they have stocked up on reserves for the winter they expect to come. There is also a noticeable difference in the brood pile. Most of the brood will be larvae with little to no pupae at all and no new eggs to be found. Gradually induce hibernation by first removing them from heat for a few days to a week in the fall (68F – 65F). Next put them in a wine cooler or other cold area around 60F for a few days to a week. Following this, reduce the temp down another 5 degrees to 55F. Leave them at this temperature for approximately 8-10 weeks before slowly introducing warmer temps. Never remove a colony from hibernation without slowly allowing them to warm up over several days to weeks like they would in nature. Ants are not meant to handle such drastic temperature swings and simply putting them in a wine cooler or taking them out of a wine cooler can shock your colony and even kill your queen.  Your colony will not require food during hibernation, but they will require water & humidity so be mindful they do not run out. Please Note: These hibernation instructions have been developed for the Texas population of Camponotus pennsylvanicus we sell, which don’t require nearly as long of a diapause/hibernation as other Northern populations.
