Solenopsis molesta, the thief ant, is one of the smallest, but also underrated ants. They're called molesta for a fairly good reason. One of their main food sources comes from going into the brood chambers of other ants, paralyzing the workers, and making off with the brood. These queens are just 3-4mm long, and workers can be as small as 1mm. They require very high humidity and will dry out easily, but are otherwise a fun and easy to keep species.

You might be wondering why we only sell queens in multiples, and not one-by-one. In our experience, Solenopsis molesta seems to more than double the survival rate and worker count when in multiples. However, I do not recommend founding queens in groups of larger than 5 queens. Rather, for a larger colony, keep groups of 5, and merge them right as workers begin to emerge.

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.

Hey! This is a live product. If you are purchasing ants during the winter months, please remember to purchase the "Winter Shipping (Live Guarantee) (72 hour heat pack + 1 inch foam cushion)" in order to guarantee the order. 

Live Guarantee Policy

If live insects arrive cold or flooded please handle with care. Many of these colonies typically pop back up within a few hours. All DOA claims must be made within 24 hours after receiving your insects. Any order with a unacceptable mortality rate, but with a viable colony (e.g. less workers than in the range advertised, less queens or workers than advertised) can be compensated with store credit equal to the loss of value in the shipment, including shipping and extra packaging. Any order with DOAs, but which do not fall out of the initially advertised/promised range of workers will NOT be compensated.

DOA claims which are a total loss will be re-shipped 1 more time FREE of charge with photographic evidence. Orders where shipping is more than 30% of the total value of the order will be refunded proportionally to the loss of value in the shipment, INCLUDING test tube inserts which are purchased with the colony.

We guarantee live arrival on Xpresspost and priority shipments, as well as pickup and local delivery. Only orders that are accepted on the first delivery attempt will be eligible for DOA credit, no exceptions.

Live guarantee is VOID if you choose expedited shipping. In the winter, it is VOID if no extra packing is purchased. Fertility guarantee claims or live guarantee claims made within the month after arrival must be made with a timestamped photo of BOTH the queen alive upon arrival AND a timestamped photo of the dead specimens.

Expedited shipping can be a budget friendly method but does not always have the best results. If your order is going to be in transit more than 3 business days please do not choose this method or choose at your own risk.


Please note that orders to outdoor community mail boxes, or other outdoor locations void our live guarantee. If your address consists of an outdoor mail box or location, please make arrangements to have the order delivered to a friends house, or to your place of employment.

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
