Look, I get it. Nobody wants to deal with pests invading their home or business.

Pest Identification Guide: Denver, CO

Mice: The Sneaky Invaders

Mice are common in Denver homes and businesses. They can sneak into even the tiniest cracks and crevices. Here’s how to spot them:

• Small, brown bodies with big ears and tails
• Fecal pellets near entry points or food sources
• Nocturnal activity; you might see tracks in dusty areas

Pitfall: DIY traps often don’t work well for severe infestations. If you see signs of mice, call a professional.

Spiders: Webs and Bites

Spiders are another common pest in Denver. They spin webs and can be found both indoors and outdoors.

• Common species include black widows and brown recluses
• Look for webbing near corners, windows, or under furniture
• Bite marks on skin; seek medical attention if bitten by a suspected venomous spider

Pitfall: DIY sprays can be ineffective. If you have multiple spiders or webs, it’s time to call an exterminator.

Ants: The Tiny Troublemakers

Ants are persistent and can come in various species, like carpenter ants and pavement ants.

Adult: Reproductive capacity varies; some species have multiple generations per year. Lifespan ranges from weeks to months.

Peak Activity: Ants are most active in spring and fall, while mice activity peaks during winter and early spring. Spiders and wasps are more active in warm weather.
