Norway Rat resting in corner

Rats can invade your property to hoard food and find shelter. Due to their intelligence, rats can elude capture by being cautious when new objects are introduced into their environment. If a new “food source” makes them sick, rats will warn others in the colony. Because of this, rats can evade many consumer rodent products.

Norway rats and Wood rats are the most common rats we encounter in the Denver Metro area. They live and thrive in cities, suburbs, and open spaces – putting them in close contact with your home. Whether rats are burrowing in the backyard or nesting in the crawlspace or attic, you don’t want to share your space with them. Here are a few things to be on the lookout for because once rats invade your home they can reproduce quickly.

  1. Rat Holes: 
    • In the yard rat holes and tunnels can be a very visible sign of a rat infestation. Rat holes are typically about 2 inches in diameter and tunnels may lead under sheds, patios or other structures on your property.
  2. Rat Droppings: 
    • Rat droppings are another visible sign of rat activity on a property or in a structure. Rat droppings will be larger than mouse droppings and are anywhere from 1/2-3/4 inches long. Norway rat droppings typically have blunt ends but dropping shape can vary by rat species.
  3. Rat Runways & Gnawing: 
    • Rats often leave behind smudges, grease marks and evidence of gnawing along their travel routes. Rat markings are typically larger and more distinct than those left by mice. If you find lots of markings along baseboards or evidence of chewing with distinct teeth marks look for other evidence of rat activity.
  4. Rat Noises in Walls & Ceiling Spaces: 
    • Rats are typically active during the night (12am-4am) so if you hear climbing, scratching and scurrying in walls or ceilings spaces while you are trying to sleep you may have a rat infestation.
  5. Rat Odor & Nesting Material: 
    • Rat infestations also have a telltale smell of musky ammonia that doesn’t dissipate.
    • Nesting material such as insulation, sticks and natural grasses often accompanies the distinct smell of a rat infestation. Rats will often have one large nest in a crawlspace, under a deck, or in an attic space.
  6. Rat Sightings: 
    • Finally, rat sightings inside the structure are a strong indication of a large infestation because rats tend to avoid human interaction.


Since rats can thrive in the open spaces and canals woven into Denver’s residential communities rat activity near businesses and homes is quite common. So what can you do to protect your property against a rat infestation?

  1. Make Habitat Modifications: 
    • Keep shrubs trimmed and consider removing evergreen shrubs altogether as rats (and other rodents) favor burrowing within their protection.
    • Eliminate brush or debris along the exterior structure to limit additional rat habitat and nesting materials.
  2. Limit Rat Food Sources on Your Property: 
    • Keep trash stored in receptacles with a lid and avoid open compost piles as they provide an excellent food source for rats.
    • If you have a chicken run, make sure to keep all food stored in tightly sealed containers and work to eliminate rat entry points into the chicken coop. Remember that rats can tunnel under a structure or fence line so its a good idea to install a rat barrier sub-grade as well.
  3. Repair Rat Entry Points:
    • Rats like a warm place to live so even if you keep habitat/food/water sources at a minimum rats may enter openings in the structure to get protection from the elements. Having your home or business regularly inspected for rat entry points and performing repairs with chew resistant materials can limit potential rat access points.
  4. Get Professional Rat Control:
    • Schedule regular rat control services along the exterior of your home or business to maintain exterior rodent populations.
