Formica ants for example, have a very strong scent that resembles a bitter or foul odor. Too many of them together create such a strong odor that will cause you to leave the area.

If your sense of smell is sensitive to urine, vinegar or ammonia, you will not wish to be near this location.

Some people describe that smell to resemble ammonia, vinegar or urine. This is why it’s a bad idea to step on them.

It is a very powerful defense mechanism for these ants. Odor is how these ants can spread their colony and become multiple colonies in a process known as budding.

If you are trying to use chemicals against them,  they will sense the odor and bud to spread out into other colonies.

If you are smelling a strange pungent odor, but you can’t trace where it is coming from, there is a chance that you may have an infestation of odorous house ants.


Ants are attracted to urine because there is glucose inside it. Your urine also contains enough water and minerals that ants can thrive on. It is quite normal for ants to be attracted to urine.
