Common Fall Pests

As temperatures drop and the outdoors becomes less and less hospitable, animals and insects all seek shelter from the elements. Rodents, bed bugs, cockroaches, and ants are four of the most common pests that might find their way into your home during the fall months. They’re also some of the most difficult pests to treat and are best handled by a professional.


Mice, Rats, and Other Rodents

As summer comes to a close and warm shelter becomes more and more difficult to find outdoors, rodents often find their way inside of homes and settle into attics, basements, walls, cupboards, and other hidden areas.

Rodents are the most high-priority pest to prevent and treat, as they carry numerous diseases and can cause significant structural damage. Structural damage isn’t limited to wood, either — many rodents are known to chew through electrical wiring and can put your property at risk of a fire.

Moreover, rodents breed quickly and can multiply in just a few weeks. This makes it both difficult to treat an infestation on your own and incredibly important to seek professional rodent control if you’ve discovered mice, rats, or another kind of rodent in your home.

In addition to following the steps at the bottom of this page to prevent rodents from making their way inside, be on the lookout for the following signs of an infestation:

  • Musky or pungent odor

  • Gnaw marks on wood, furniture, and food packaging

  • Small droppings (usually no more than .25 inches in length) in secluded areas

  • Nesting materials such as shredded paper, insulation, and wood

  • Unusual pet behavior

Bed Bugs

Bed bugs are brown, oval-shaped insects that feed on human blood and multiply quickly. Although a bed bug infestation can occur at any time of the year, fall is when many residents find themselves needing to invest in professional bed bug treatment. In many cases, bed bugs hitch a ride home during summer vacations and are able to multiply undetected for several months. In others, they’re able to transfer from home to home as children go back to school and have more frequent home-to-home contact.

Bed bugs don’t normally pose significant health risks, but the sores their bites create can make it difficult to get a good night’s sleep. Four of the most common signs of a bed bug infestation include:

  • Shells and/or molted skins

  • Small bloodstains on bedding

  • Clustered red welts that itch and burn

  • White eggs approximately 1 millimeter in length

Few pests alarm homeowners quite like cockroaches, and understandably so! Cockroaches often make their way through garbage, sewers, and other areas in which they can pick up bacteria and pathogens that are spread wherever they go. They can also exacerbate asthma and allergies and susceptible individuals, making it extremely important to take steps to keep them out and treat infestations as soon as they’re discovered.

Cockroaches are primarily active at night, which can make them more difficult to spot than some other pests, and the fact that they can take up residence almost anywhere only compounds the problem. If you notice any of the following signs, contact our team to schedule an inspection:

  • Dark-brown egg casings

  • Exoskeleton sheddings

  • Dark droppings that look similar to ground coffee

  • Musty odor near drains, cupboards, and other secluded spaces



Like the pests discussed in the previous three sections, ants have a difficult time thriving once summer transitions into fall and the temperature begins to drop. New Hampshire is home to several different kinds of ants, but carpenter ants are by far the most destructive and worrisome species that could take up residence in your property.

Carpenter ants can be difficult to spot due to the fact that they often make their way inside through small cracks and crevices before nesting inside of walls and other sealed-off areas. However, there are a few subtle signs to watch for this fall:

  • Piles of wood shavings in secluded areas

  • Winged ants crawling out of floorboards, walls, and other indoor areas

  • Shed wings near windows, doors, vents, and other access points

  • Subtle rustling noises in walls and woodwork

Tips for Keeping Pests Out This Fall


Rake and Dispose of Leaves as Soon as Possible

Is there anything quite as picturesque as a pile of fiery red, orange, and yellow leaves on a crisp fall afternoon? We’ll leave the ultimate verdict up to you while recommending that you take a picture instead of leaving the pile in your yard for more than a few days. Leaves provide all of the pests discussed above — as well as many others — with shelter and can bring them into close proximity with your home. Once that shelter has been disposed of, they’ll come looking for another place to take refuge.

On a related note, keep the rest of your landscape maintained to deter pests. Make sure that you’ve cleared leaves and other debris from your gutters; winterize your barbeque and clean it thoroughly; and if you plan to enjoy fires that require real wood, be sure to store the lumber at least 20 feet away from your home.


Winterize Your Property

Although there are still several months before the first day of winter, it’s never too early to winterize your property and ensure that it’s protected from both pests and energy loss.

Start by examining your home’s exterior for any areas that could provide pests with easy access to your home. Look for cracks, crevices, and other openings that could provide unhindered access to heat, food, and water. Fill and repair any openings you discover. If you have larger gaps and openings that can’t be filled with caulk or fixed with a new screen, steel wool can act as an effective short-term fix that prevents pests from entering. However, keep in mind that steel wool won’t protect you from heat loss. Ultimately, investing in whatever it takes to properly seal your home will protect you from pests and reduce the amount of heat you consume when you turn your furnace on!


Inspect Secluded Areas

As you can see from the discussion above, many of the most common pests we treat during the fall season take refuge in secluded areas that aren’t frequently used. It’s always a good idea to inspect your basement, crawl space, attic, and other less frequently used areas of your home to look for anything out of the ordinary. Keep an eye out for all of the common signs of the pests discussed above and, if something doesn’t look right, you can always contact our team to schedule a free inspection. Here at Anchor Pest Services, we believe that it’s always best to err on the side of caution!
