Red Imported Fire Ants

It’s a hot summer afternoon, and you spot a trail of ants marching across your kitchen counter. In Louisiana, ants are most active during the warmer months of spring and summer, particularly early morning and late afternoon.

What triggers this increased ant activity in Louisiana? Read on to learn when common ants are most active and how to keep them at bay.

Key Takeaways

  • Ants are most active in Louisiana during the warmer months of spring and summer, with fewer sightings in the cooler fall and winter.
  • Humid weather and heavy rain often drive ants indoors, increasing the chances of infestations.
  • Common native and invasive ants in Louisiana are more active at different times of the year.
  • Steps like keeping your home clean can help prevent ant problems, but professional help may be needed for stubborn infestations.

WHEN DO ANTS TYPICALLY SHOW UP IN LOUISIANA?

Ant activity in Louisiana fluctuates with the changing seasons. Spring can bring a notable increase in ant appearances, continuing into the hot summer months. On the other hand, fall and winter may offer some relief.

Spring Season: Prepare for Ant Activity

Spring marks the beginning of ant season in Louisiana. Warmer temperatures and increased moisture create ideal conditions for ants to become active.

Species like red imported fire ants and carpenter ants start foraging for food. Ant activity often peaks during this time, leading to potential infestations around homes and gardens.

Summer Season: Ant Levels Remain High

Summer continues with the high level of ant activity seen in spring. The consistently warm temperatures and humidity in Louisiana during these months allow ants to thrive.

During summer, odorous house ants often invade homes looking for food and water. Carpenter ants might start targeting wooden structures for nesting, leading to potential damage.

Fall and Winter: Ant Activity Decreases 

As temperatures drop in fall and winter, ant activity decreases. Ant colonies slow down their foraging efforts, and the number of active ants seen outdoors reduces significantly.

Though less active, common species of ants don’t disappear entirely. They may seek warmth inside homes, leading to occasional indoor sightings.
