Don't Be Fooled: Identifying Rat Burrows in Stoneham, MA

Tim Frazer • October 10, 2025

When it comes to pest identification, looks can be deceiving. As experienced pest control professionals serving Stoneham, MA, we often encounter property owners who mistake serious rodent infestations for harmless wildlife activity. The photos above are a perfect example of this common misconception.


These Aren't Chipmunk Holes

At first glance, these burrow openings nestled among rocks and autumn leaves might seem like the work of chipmunks. After all, chipmunks are common in our area and love to make their homes in stone walls and rocky areas. However, our trained eyes quickly identified these as rat burrows – a much more concerning discovery for any property owner.

What Makes These Rat Burrows?

Several telltale signs helped us identify these as rat burrows rather than chipmunk holes:


Location and Structure: Notice how these burrows are positioned among the stone foundation and rocks. Rats, particularly Norway rats, are excellent burrowers that prefer to dig near foundations, under rocks, and along walls where they feel protected. The burrows in these images show the strategic placement rats favor – close to structure and with easy access to shelter.


Burrow Size: While both rats and chipmunks create holes around 2-3 inches in diameter, rat burrows tend to have a slightly larger, more worn appearance from repeated use. The openings in these photos show the smooth, well-trafficked edges characteristic of active rat burrows.


Multiple Entry Points: In the second and third images, you can see evidence of multiple burrow openings in close proximity. Rats create complex burrow systems with several entrances and exits for safety. This network of holes is more indicative of rat activity than the simpler, single-entrance burrows chipmunks typically create.


Lack of Food Storage Evidence: Chipmunks are diurnal (active during the day) and often leave evidence of their food caching behavior near their burrows. Rats, being more nocturnal and cautious, keep their burrow entrances cleaner and less obvious.

Why This Matters for Stoneham Homeowners

Stoneham's mix of older homes, stone foundations, and wooded areas creates ideal conditions for rat populations. The rocky terrain shown in these photos is extremely common throughout our community, making it easy for rats to establish hidden colonies right under homeowners' noses.


The Risks of Rat Burrows

Unlike chipmunks, rats pose significant health and property risks:

  • Structural Damage: Rat burrows can undermine foundations, compromise stonework, and damage underground utilities
  • Health Hazards: Rats carry diseases including leptospirosis, hantavirus, and salmonella
  • Rapid Reproduction: A single rat pair can produce 2,000 descendants in one year under ideal conditions
  • Secondary Pests: Rats bring fleas, mites, and ticks onto your property


What to Do If You Spot Similar Burrows

If you notice burrow holes on your property that resemble those in these photos:

  1. Don't disturb them – This could cause rats to relocate elsewhere on your property
  2. Document what you see – Take photos and note the location and number of holes
  3. Look for other signs – Check for droppings, gnaw marks, rub marks along walls, or tracks
  4. Call professional rodent control specialists immediately – Rat infestations require expert intervention to eliminate completely
