Ants have their own form of fermentation that produces antibiotics.

The claim that ants have their own form of fermentation which produces antibiotics is partially supported by available web evidence. Multiple studies indicate that ants produce antibiotics to combat bacteria, and some use fermentation processes for activities like food preservation. For example, ants are noted for producing acids such as formic acid, which are used in bacterial control and potentially in fermentation processes. These findings suggest that while ants do have biological processes related to fermentation and antibiotic production, the specific assertion that they perform fermentation to produce antibiotics as a general practice is not definitively proven. Nevertheless, evidence of ant fermentation used in food sanitation and bacterial elimination supports a component of the claim.
