Why do Ants Appear after Rain?

Down came the rain and washed the…ant hill out?

There are many types of ants, each with their own habitat and underground network, but what happens to their homes during the rain? How damaging is rain to ants?

Most ants have extensive tunnels and preventative measures for rain. I’m sure we’ve all seen ant hills (and some of us may have even knocked a few over!) but there is much more to these little mounds than meets the eye.

Although their homes seem shallow, most ant hills will extend about a foot underground! Some factors that determine whether rain will enter the nest include the type of soil and the amount of rain.

Some smart little ants will even make sure to nest in the types of soil that easily absorb moisture and dry quickly. Inside each ant hill is a complicated and vast network of tunnels.

These tunnels act as guards against rain. If rain enters, it will most likely not pool because water usually keeps moving until it reaches groundwater.

Now, it is more than likely that a few casualties will occur. Many ants will be washed away or drowned, but ant colonies are so enormous that enough survive so that they can rebuild their nests.

So, here are some of the reasons that ants appear after rain:

  • Their nests are damaged and they need to rebuild.
  • Their nests are completely destroyed and they need to find a new home.
  • They seek new food sources after the rain.

Unfortunately, once in a while, these new homes they find are our homes!
