Which of the following is true about Odorous House Ants?

Odorous House Ants are particularly known for their preference for sweet foods rather than protein-rich foods. This species enjoys sugary substances, making them more attracted to things like honeydew from aphids, sugars, and other sweet products found in households.

The correct response highlights that they vary in size among workers. In a single colony, you can find a range of worker ants that differ in size due to the presence of different castes. This size variation helps facilitate various tasks within the colony.

While it's important to note that Odorous House Ants can swarm, they primarily do so outside. Their behavior is influenced by environmental conditions rather than being a common activity inside the colony, which makes this aspect less typical for discussions around their behavior.

In contrast to the false statement about them being larger than Argentine Ants, it is worth noting that Odorous House Ants are generally smaller than several other ant species, including Argentine Ants. Hence, the size comparison is not a defining characteristic of Odorous House Ants.
