Aurora, Colorado Pest Control Trends: Why Heat Is Increasing Ant and Spider Activity This Year
Aurora homes see increased pest activity with rising temperatures.
Aurora homeowners are noticing more pest activity this year, especially ants and spiders. With hotter stretches across the Denver metro area, pest pressure can increase around homes, businesses, garages, basements, landscaping, and entry points.
At Apex Pest Management, we are seeing the same pattern locally in Aurora: when the heat rises, insects become more active, and pests start looking for food, water, shade, and shelter. That is when ants begin trailing into kitchens, bathrooms, laundry rooms, pet feeding areas, and basements. It is also when spider activity becomes more noticeable around garages, window wells, porches, exterior lights, storage areas, and lower-level living spaces.
Colorado’s summer outlook has pointed toward hotter conditions, and the National Weather Service/NOAA local climate resources continue tracking Denver-area heat and seasonal climate patterns. Warmer weather can push pest activity earlier and increase pressure around structures.
Why Heat Matters for Pest Control in Aurora
Aurora has a unique mix of older homes, newer neighborhoods, open space, dry landscaping, commercial buildings, and properties near fields, trails, drainage areas, and reservoirs. Areas near Southlands, E-470, Buckley, Aurora Reservoir, Tollgate Creek, Seven Hills, Meadow Hills, and older west Aurora neighborhoods can all experience different types of pest pressure depending on moisture, landscaping, construction gaps, and surrounding habitat.
When temperatures climb, insects do not just disappear. Many become more active. They search for moisture, food, and cooler protected areas. That is why pest issues often show up inside during hot summer weather, especially around kitchens, bathrooms, basements, crawlspaces, utility rooms, and garages.
Ant Activity Is One of the Biggest Trends This Year
Ants are one of the most common pest issues in Colorado homes. Colorado State University Extension notes that most ants found inside homes are nesting outdoors and entering to search for food or water. They also explain that removing food and water sources can reduce ant visits and make baiting more effective.
In Aurora, we commonly see ants enter through:
Foundation cracks
Garage edges
Door thresholds
Window frames
Utility penetrations
Gaps around siding or concrete
Landscaping beds touching the foundation
Areas near pet food, trash cans, and moisture
The biggest mistake homeowners make is only spraying the ants they see inside. That may kill a few visible ants, but it usually does not address the colony, trail system, or exterior entry points. For long-term control, the exterior source needs to be inspected and treated correctly.
Why Spiders Are More Noticeable During Hot Weather
Spiders are usually a sign that other insects are active nearby. Colorado State University Extension explains that spiders feed on insects and other arthropods, which makes them beneficial in nature, but they become a nuisance when they are around living areas, garages, basements, storage rooms, and entry points.
In Aurora homes, spider activity often increases around:
Garages
Basements
Crawlspaces
Window wells
Exterior lighting
Rock beds
Wood piles
Decks and patios
Fence lines
Storage areas
Eaves and porch corners
When insect activity increases, spiders follow the food source. That is why a good spider treatment should not only remove webs and treat spider harborages, but also reduce the insects attracting them in the first place.
What Aurora Homeowners Can Do Right Now
A few small steps can make a big difference during the hotter months:
1. Keep pet food sealed and cleaned up.
Ants are commonly found around pet bowls, especially when food is left out overnight.
2. Move trash cans away from the home.
Trash areas can attract ants, flies, wasps, and other insects that eventually bring more pest activity close to the structure.
3. Trim landscaping away from the foundation.
Heavy vegetation, mulch, leaves, and ground cover against the home can give ants and spiders protected areas to live and travel.
4. Reduce exterior lighting when possible.
Lights attract flying insects, and those insects attract spiders.
5. Seal obvious gaps.
Check door sweeps, garage seals, utility lines, foundation cracks, and window frames.
6. Clean webs regularly.
Web removal helps reduce spider pressure and makes it easier to monitor new activity.
Why Professional Pest Control Helps
A professional pest control service is not just about spraying. A proper treatment should include inspection, identification, targeted product placement, exterior perimeter treatment, entry point focus, web removal, baiting when needed, and recommendations for prevention.
At Apex Pest Management, our goal is to protect the home from the outside in. For ants, that means locating trails, entry points, nesting areas, and conditions that are attracting activity. For spiders, that means treating common harborages, removing webs, reducing insect pressure, and helping prevent future activity.
