The short answer is “no”, although it is a difficult question to answer partly because of the sheer diversity of ants – there are 13,000 named species on the planet!
And despite the persistent rumours, Wayne says there's no evidence to show that ants can predict rain. "There is no scientific evidence of any relationship between ants and rain except to say that we know that ants behave in certain ways after rain."
Rain drives ants up from their flooded nests, as most ant species live in shallow, underground nests. When it rains, these nests can flood in a matter of minutes. If the rain has been heavy enough, the entire colony may search out a new place to live.
Ants Build a Fortress and Tunnel System
It absorbs water, dries quickly, and causes the water to bead and run off. Underneath the ground, ants will burrow tunnels that act like an intricate network of storm drains. If rain does come into their tunnel system, it will pass through without pooling.
Many people believe that ant infestations mean that their homes are unclean, but often, that's not the case. Instead, ants commonly come inside during times of heavy rains because—like humans—they want a safe, dry place to live.
Milder winters provide ant colonies with the resources needed to grow larger and spread out into areas where they may not have thrived before. Because of this, homeowners can expect to see an increase in ant activity in 2022. Some of which may include species of ants that have migrated to a new area.

When it rains, ants that live on the ground surface or underground are at risk of drowning. Therefore, the workers pick up eggs and other immature ants and seek out shelter in a dry place. Sometimes, that just happens to be your home.
Heavy rains will flush ants out of the wet soil. The ants search for food and safety in higher grounds; if it is dry, they will of course feel even better. Our homes, sadly, are one of their favorite places to seek shelter if they can find a way inside.
According to a study published in the open-access journal PLoS ONE, insects modify calling and mating behavior in anticipation of storms. Curcurbit beetle, shown here, the true armyworm moth and the potato aphid can predict adverse weather conditions.
Spiders love warm weather, and when a rainstorm hits, temperatures usually drop. Spiders will seek warmer places to wait out the rain, like your house. In addition to wanting to stay warm and dry, spiders will also wander into homes after a rainstorm to find prey.
Ant Encounters and Omens
Some believe that ants in one's home is good luck because it signifies an excess of resources. Ants may also indicate progress, so ants in the home can be a good sign for career advancement.
Fire ants can't survive for prolonged periods in conditions that freeze soil as deep as they are nesting. The northern boundaries of fire ant infestation are estimated to be areas with a minimum temperature of 10 degrees F.
After it rains, ants will be actively searching for food. Consider scattering bait around their home. Note, bait should not be applied directly on top of the mound as it can be perceived as an attack and the ants will not eat the bait.
Ants come indoors because they're seeking water.
If your area is experiencing a drought, or the weather is simply hot and dry, ants may invade homes for moisture and food. Kitchens and bathrooms are especially vulnerable to ant infestations.
Ants usually come indoors in search of food or nesting habitat. Even small amounts of food, like pet food crumbs, can attract hordes of industrious ants. Ants are one of Earth's most successful animals, and comprise more than 13,000 species.
They are most active at night. Workers emerge from the nest about 15 minutes after sundown.
Ants are famous in the world of biology for using pheromones to warn other ants about danger or guide them to food.
Ants will release a distress chemical, much like some species of wasp, to indicate there is a threat to the colony and cause the nest to swarm and attack the threat. Ants are also known to use sound as a way to communicate.
Scientists have known for decades that ants use a variety of small chemicals known as pheromones to communicate. Perhaps the most classic example is the trail of pheromones the insects place as they walk. Those behind them follow this trail, leading to long lines of ants marching one by one.
Killing ants will, definitely, attract more ants because the dead ants release pheromones that attract or rather alert, nearby ants.
Fact is, there is no single “ant season.” Ants may choose to enter buildings at any time of year seeking shelter from the elements, whether that means rain and cold or dry heat. And, of course, food and moisture are always attractants.
Two of the best ways to eliminate ants are Borax and diatomaceous earth. Essential oils, including peppermint and clove, are a natural way to repel and kill ants. Food and moisture attract ants, so keep your home clean and dry to get rid of ants permanently.
