Since 2019, we’ve helped clients across Denver, Boulder, Lakewood, Arvada, and nearby communities manage rat problems effectively. Backed by Pest Arrest LLC, our approach combines practical techniques with a warranty that covers follow-up visits if rats return.

Step-by-Step Rat Control That Gets Results

We start with a detailed inspection to identify entry points, nesting areas, and signs of rodent activity. From there, we create a targeted plan tailored to your property’s layout.

Our treatments use tamper-resistant bait stations placed strategically to reduce risks to children and pets while effectively addressing the rat population. Many clients notice a decline in activity within about two weeks.

After the initial phase, we return for a follow-up visit to monitor progress and make any necessary adjustments. Once this two-week follow-up is completed, a 3-month warranty period begins, covering any additional rat activity during that time at no extra cost. In most cases, this follow-up can be done without requiring you to be home, keeping the process simple and convenient.

Why Store-Bought Solutions Often Disappoint

Hardware store traps and baits can reduce numbers temporarily but rarely fix the root cause. Rats are cautious and adapt quickly to avoid traps, meaning infestations often persist and cause ongoing damage.

Our coordinated approach is designed to outpace rats’ ability to adapt, providing more consistent and durable results than trapping alone.

Tips to Help Prevent Rodents from Returning

A few simple precautions can make your property less inviting to rodents:

  • Keep indoor and outdoor areas tidy and free of clutter
  • Store food securely in sealed containers
  • Remove potential nesting spots like stacked firewood or overgrown vegetation

These steps complement professional treatments and help reduce the likelihood of future infestations.

Why Rats Are a Year-Round Problem in the Denver Area

In colder months, they seek shelter indoors for warmth and food. During warmer weather, they may remain in garages, sheds, and outdoor storage areas. Because they breed quickly and adapt to avoid traps, a small issue can turn into a serious infestation in weeks.

Urban locations like Denver and Boulder provide rats with hidden shelter in attics, crawl spaces, and behind walls. In suburban areas such as Lakewood and Arvada, they may nest in sheds, near woodpiles, or under decks, always close to a steady food source.

Mice vs. Rats: Why the Approach Matters

Mice and rats may be related, but their behavior, size, and damage potential are very different. Mice are smaller, about 2.5 to 4 inches long, with large ears, pointed snouts, and fine-haired tails. They’re curious, which makes them easier to trap, but they reproduce quickly and can cause widespread contamination indoors.

Rats are larger, often 7 to 9 inches long, with thicker, nearly hairless tails and blunt snouts. They’re more destructive, capable of chewing through wood, plastic, and even softer metals. Their cautious nature makes them harder to trap, and they can cause significant structural and wiring damage if not addressed promptly. Because of this, rat control often involves more strategic bait placement, stronger exclusion measures, and a longer treatment plan than mouse control.

If you’re not sure which rodent you have, Mice Masters can identify the issue and recommend the right plan.

Preventative Plans
The ARREST System – Rodent Refill Service provides ongoing rodent control for homes and businesses after initial treatment. Once your property is set up for protection, our technicians schedule refills every 3, 4, or 6 months based on your needs. This ensures bait stations stay stocked and rodent activity remains under control.

Common Signs You Have a Rat Problem

  • Droppings along walls, in cupboards, or near stored food
  • Gnaw marks on packaging, wiring, or wood
  • Scratching or scurrying sounds, especially at night
  • Nests made from shredded paper, insulation, or fabric in hidden areas

Seeing a single rat often means there are more nearby.
