This very popular blog post has been refreshed and updated for Spring 2024 (and thereafter).

Photo caption: A legion _{(not an army, but part thereof!)} of sugar ants committed mass suicide in my bottle of honey. In honour of those that might resurrect – I can see some of them will – I pooled it in the sink and gave them a chance to extract themselves (and several did). A few less foolhardy brothers and sisters are supping from the edges.

It’s spring again— and people don’t know what to make of the teeny-tiny ants that march indoors like school children on spring and summer days (when they should be outside!). They can’t be mistaken for carpenter ants. But, unfortunately for them and all the other ant species that aren’t carpenter ants, all searches end up on results about killing them. As if they were as dangerous as carpenter ants. Carpenter ants won’t hurt you, but their infestations are dangerous to your house – they devour wood.  They’re the only ones you need to be vigilant about. (OK, maybe fire ants too, but usually they’re outdoors, minding their own business).

Common talk, mass media, and the extermination industry has effectively enabled people to think that insects are disgusting and undesirable. This is just flat-out wrong. Bugs aren’t your enemy. All it takes to realize that, is to observe them objectively, doing nothing but watch—and if that isn’t enough, it always helps to do a little research.

Of course, when you try to do some research, you have to get past the “get rid of” them websites. The truth takes lot more digging. So that’s what this blog post is about.

So, those teeny-tiny ants you see in spring, visiting your plants, maybe visiting the fruit on your kitchen counter? The name of this kind of ant is Tapinoma sessile. Here’s the path I took to research it some more:

This year I decided to take the Nature Conservancy of Canada’s challenge and do a biological census of my front and back yards. It’s an event where you use the iNaturalist app to record as many species as you can find-and-identify in your own back (front) yard. Sign up and get your instructions here.

If you happen to be in my area (Little Burgundy, le Sud-Ouest, Montreal), then you are welcome to come by and discover even more, because I’m expecting to have no shortage of plants and insects to identify. Seek, an ID app by iNaturalist, will be useful for this, and I have some ID books on hand as well. Just send me a message or knock on my door, if you know where I am/can find me (I’ll be writing #NCCBioblitz on the sidewalk outside, and using the hashtag and location on my Instagram posts. I may even be outside doing it.
