Why Ants Invade in Spring (and How to Stop Them)

Ants

Ants scout for food and water as temperatures rise. Here's how to cut them off before they establish a colony.

As soil temperatures climb, ant colonies send out scouts looking for food and water. A single scout that finds a reliable source lays a pheromone trail — and within days you have a highway into your kitchen.

What to do

  • Seal cracks around the foundation and windows.
  • Store food in airtight containers.
  • Wipe down counters to remove scent trails.
  • Use baiting (not just sprays) so the colony is eliminated at the source.
