Paratrechina longicornis, or the Black Crazy Ant, is an unusual invasive species in heated greenhouses and tropical countries across the world. What makes these ants particularly unique is their ability to clone and create supercolonies. Black crazy ant queens can produce copies of themselves in genetically isolated populations, and colonies from hundreds of miles away will often be wiling to merge and co-operate, creating one of the most united forces in interspecies ant conflicts.

All queens are sourced legally through collecting in areas surrounding greenhouses, and then captive bred, as well as imported through permits.

As far as we know, we are the only legal suppliers of the species, as it is illegal to import them without a permit.

Test tube inserts are upgrades to the test tube setups provided. If purchased, they come with a dark hood to lower light levels for the colony, an insert which provides a living space, and a feeding insert to provide food for the colony.

Ungrouted inserts are a blank plastic insert which helps provide a more suitable space for the ants to grip (as opposed to glass tubes), while grouted inserts are bedded with a substrate which helps distribute humidity more evenly throughout the test tube, and helps certain ants create their cocoons more easily. Overall, grouted inserts are more comfortable for the ants.

You will NOT need an insert for colonies in test tubes, but it does help for certain species. IF you are moving the ants into a nest immediately, do NOT get a test tube insert.

This species comes from more tropical areas than Canada, and are not cold-tolerant. Thus, we will not ship them in the winter

Just a warning, we will NOT ship live ants into the US unless the receiver has a permit. If such an order is made, it will be refunded, minus a 10% processing fee and restocking fee
