Overwintering Habits of AZ Pests

Keeping Arizona Insects Out Of Your Home This Winter

Below is a list of common Arizona pests and suggestions focusing on how to keep them out of your yard and home. For most insects, removing their food sources, sealing your house’s cracks and openings with caulk, screening vents and crawl space, and using weather stripping to close gaps will keep them out. For most insects, excess moisture is attractive. Keeping your home clean and dry with no leaks will keep them out. If you see signs of infestation contact Green Home Pest to schedule a consultation.

First, it’s important to keep an eye out for the pests that will be active in your home throughout winter –

Black Widows and Brown Spiders:

Spiders overwinter as young adults in buildings or sheltered places outdoors. Spiders and their webs can be vacuumed away indoors but use caution outdoors and in outbuildings. Spiders prefer dark, dank places like basements, garages and crawl spaces. They are also found outside beneath rocks and piles of wood.


Ants will seek out the humid areas near food and water. Their nests are usually in empty wall space, behind baseboards, under floors, in furniture, and between linens. They use electric and telephone wires to travel through the wall and between floors. The first sighting of ants in your home is the reason for concern.

Subterranean and Dry Wood Termites:

Termites like temperatures between 75 and 95 degrees. In mild climates, termites are active year-round. They can overwinter in tree stumps, large wooden objects, and logs above ground and may move to depths of 40 inches into the ground in late fall. Don’t let moisture accumulate around your home. Keep your gutters, downspouts and splash blocks working properly.

Fleas and Dog Ticks:

Even if your pets wear flea and tick collars, your home may be invaded. Washing all pet bedding and vacuuming away as many as you can is a good start to eliminate them. A dehumidifier can keep the humidity less than 50% and this will kill adult fleas and larva as well as stop flea eggs from hatching. For ticks, check your dog after every outing. When walking your dog, keep them away from tall grass and weeds.

Pests outside of your home change their behavior due to the lower temperatures at night during winter-

It’s unlikely to see any active snakes during the winter months, but they can still be a potential threat as they like to hibernate under homes or in sheds. While they may initially seem slow when their hibernation is interrupted they can strike quickly without notice.

Bees and Wasps

With the exception of extremely warm days, bee and wasp activity during winter months drops altogether. However, if the hive is threatened they may still attack despite their lethargy. If you do spot a hive contact Phoenix pest control experts, Green Home Pest, we’ll safely remove the nest from your property.
