There’s
an army not far from your house…and it’s marching toward your
pantry. It will only grow bigger unless you do something.
Around
40,000 ants—the size of a typical colony—are always poised to
strike, but as any tactical genius would do, it won’t attempt a
head-on attack. It will exploit any windows, cracks, or other viable
openings as an opportunity to breach the house. Defeating a massive
army requires understanding how they maneuver.
Obviously,
the ants are invading for food. They split up in search of food while
leaving a trail of pheromones from their nest, much like leaving a
trail to guide you back to camp in case you get lost in the
wilderness. As soon as one ant finds a source of food, it will carry
what it can and return to the nest by following the pheromone trail
it left. On the way back, the successful ant leaves a new trail of
pheromones on top of the previous trail. As a result, the scent of
that trail grows stronger, attracting other ants to follow.
Destroying
this trail will effectively blind the ants and cause them to get lost
as they struggle to pick up the scent. Simple extermination can done
by scrubbing detergent, but getting rid of the pheromones won’t be
enough. You also have to seal their access points, which is a more
complicated task.
