Mouse & Rat Rodents

Mice and rats are notorious for seeking refuge indoors during the fall. As the weather cools, these rodents look for warm nesting sites and a steady supply of food. Sealing cracks and holes in your home’s foundation, storing food in airtight containers, and setting traps can help deter them from invading your space.


Loveland is home to various spider species, and some become more active in the fall. While most are harmless, the sight of spiders can be unsettling for many. Regularly cleaning and decluttering your home can discourage them from settling in. If necessary, consider professional pest control for more significant infestations.


Ants continue their relentless search for food even as the weather turns cooler. Keeping your kitchen clean and storing food properly can help prevent ant infestations. Ant baits and sprays are also available for control if needed.


Cockroaches thrive in warm, humid environments, which makes them more active during the fall. Seal cracks and crevices in your home, eliminate standing water, and ensure proper ventilation to deter these unwelcome guests.

Stink Bugs

Brown marmorated stink bugs become a nuisance as they seek shelter from the cold. They release a foul odor when disturbed, making them unpleasant housemates. Sealing gaps around windows and doors and removing vegetation near your home can help keep them at bay.

Hornets & Other Wasps

Fall marks the time when wasp and hornet colonies reach their peak populations. To avoid painful stings, take precautions like removing food sources, sealing entry points, and consulting a professional if nests are discovered.


If you have pets, be vigilant about flea control during the fall. Regularly groom and treat your pets and vacuum your home thoroughly to prevent these tiny pests from multiplying.


Loveland’s natural beauty makes outdoor activities popular in the fall. Be sure to check yourself, your family, and your pets for ticks after spending time in wooded areas to reduce the risk of tick-borne diseases.
