The Time the LIRR Fought a War Against Caterpillars

It sounds like something made up, but it wasn’t.
In 1913, Long Island Rail Road workers were locked in a quiet but very real battle along the tracks near Montauk… against caterpillars.

Not trains. Not storms. Caterpillars.

Captured in a striking early photograph, this unusual moment in Long Island history shows just how far workers had to go to keep the railroad running during a time when even tiny threats could cause big problems.

The Photo That Captured It All

  • Title: Caterpillar Warfare
  • Date: 1913
  • Photographer: Hal B. Fullerton
  • Format: Gelatin silver print
  • Collection: Hal B. Fullerton Photographs
  • What it shows: Workers posing with spraying equipment used to treat areas around the tracks

The image itself is almost surreal. A group of workers stands along the LIRR line, facing the camera with equipment in hand. No urgency. No chaos. Just a calm moment in what was, essentially, pest control on a railroad scale.

But what they were dealing with was anything but minor.

Why Caterpillars Were a Real Problem

In the early 1900s, railroads were the backbone of Long Island. Everything depended on them running safely and consistently.

And that’s where the caterpillars came in.

  • These insects fed heavily on vegetation surrounding the tracks
  • Overgrowth and damage near rail lines could impact visibility and stability
  • Left unchecked, infestations could threaten the safety and efficiency of train operations

This wasn’t just about landscaping. It was about protecting infrastructure at a time when alternatives were limited and delays had real consequences.

You’ve probably ridden past stretches of track like this without a second thought. Back then, those same areas could turn into problem zones almost overnight.

The Early Days of Chemical Warfare (the Non-Dramatic Kind)

The solution, at the time, was cutting-edge: insecticides.

  • Workers sprayed chemicals along the tracks to control caterpillar populations
  • This was considered an innovative approach in the early 20th century
  • The goal was simple: stop the damage before it spread

Another photo from the same collection shows similar scenes, reinforcing that this wasn’t a one-off effort. It was part of an ongoing strategy to manage a persistent issue.

Today, pest control is routine and largely invisible. In 1913, it was something workers had to do manually, often posing for photos in the middle of it.

A Small Battle That Meant a Lot

Looking back, “Caterpillar Warfare” feels almost quaint. But it tells a bigger story about Long Island at the time.

  • The LIRR was critical to daily life and economic growth
  • Even small threats required organized, hands-on solutions
  • Workers relied on early technology and determination to keep things running

This wasn’t about dramatics. It was about problem-solving in real time, with whatever tools were available.

Why This Still Matters

That photo from 1913 isn’t just interesting, it’s a reminder.

It shows how something as small as a caterpillar could disrupt a major system, and how people adapted quickly to deal with it.

Long Island has always been a place where big systems meet unexpected challenges. Sometimes those challenges are massive. Sometimes, they’re crawling right along the tracks.

Either way, someone had to handle it.
