Ants could also be little, however they’ll pack a pungent punch. Many species of ants launch strong-smelling chemical substances after they’re offended, threatened or being squished. Entice-jaw ants launch a chocolatey scent when irritated, whereas citronella ants earn their title from the lemony odour they offer off.
The scent of the odorous home ant, in the meantime, has been likened to blue cheese or rancid coconuts. It is because the chemical substances that it releases, methyl ketones, are additionally produced by the Penicillium micro organism that ripen blue cheese and develop on rotting coconuts.
Formic acid is one other pungent substance emitted by many ant species. Wooden ants, for instance, produce massive portions of the vinegary substance of their venom gland to spray at prey and attackers.
And when ants die of pure causes, they launch oleic acid, the primary fatty acid present in olive oil. This offers useless ants a ‘freshly dressed salad’ type of scent, which acts as a chemical cue for the remainder of the colony to scrub up the our bodies earlier than they begin to decompose.

Scents, nevertheless, are simply the tip of the iceberg since ants have a complete language based mostly on scent.
Is it doable for us to talk that language? An ad-hoc ballot of round 700 folks on X, previously referred to as Twitter, revealed that solely 20 per cent of respondents claimed a capability to scent ants. The remaining had been a bit bamboozled.
This imbalance could merely replicate a scarcity of curiosity – in any case, many individuals have by no means tried to scent an ant – however genetics can be more likely to play a job.
Simply as some persons are unable to smell out ‘asparagus urine’ resulting from a mutation in a key smell-related gene, so too a blip within the genetic code could stop some folks from detecting key ant scents.
