If you’ve ever found yourself wondering what sorts of pests you’re likely to encounter at a given time of year, look no further. Pest expectancy is a fairly easy thing to look up, but few places seem to have a handy source in which you can get all the info you want in one place. That’s where our Pest Expectancy Chart comes in! This chart is designed to accurately indicate when you can expect various pests to be a problem here in the Pacific Northwest. Faded portions denote minor activity, solid portions indicate strong activity and prevalence, and in the case of rodents, the winter months are darkened to show heavy home invasion behavior. Take a look and you’ll know what to expect in the months to come!
All bees in our region face a huge dropoff in sightings by October, with the heaviest months of activity being in the Summer months, and into Fall. Click here for more in-depth information about bees, as well as our handy nest identification guide.
These have no season, and can dominate and spread in a region all year round. They are mostly indoor pests, though can be found near dumpsters and other near-foodsource areas. The cold Winter months push them indoors, where they can survive until warmer weather, though they seldom spend much time outdoors.

Wasps are a real menace, and though they do help to maintain a variety of other insect populations, they’re not so handy when they’re stinging your kids near the barbecue or pain-swarming you while you’re trying to mow the lawn or check the mail. Always a terrible surprise. They do have a main seasonal run, which begins in early Spring (minor activity) and builds incredibly through to mid-Fall (heavy activity). Their nests grow rapidly and their numbers grow exponentially. Like bees, they mostly die out / disappear in the Winter and start over again in the Spring.

Most ants in the Pacific Northwest function year-round, but definitely have a strong drop off during the Winter months. They can survive the cold months in a warm home like yours, but the majority of us don’t see them again until Spring. Click here to learn more about controlling ants.
Like ants, spiders tend to back off in the Winter months, but there are some species who can handle the colder weather, and as always, those living in your home will do quite well, regardless of how cold it is outside. Winter is tough on spiders because while they can survive it indoors, many of the insects they catch and eat do not survive in the Winter, so it’s a sparse time to be a spider. Click here for more information we’ve compiled about local spiders.
Rats and mice thrive in Winter. The cold months push them indoors, however. As a result, Winter is when we see the most rodent home invasions. They can breed year round and proliferate in the Spring and Summer, though Winter is when you’re most likely to encounter them in your attic, garage, or even your kitchen. Pest Expectancy: Always, but far more personal and up-close in the Winter. We have a three-part series on various rodents, especially rats and mice, chock full of information here.
Carpenter ants typically don’t survive as well as sugar ants during the Winter months, but definitely proliferate in the Spring and Summer. They can expand quickly and form long, enormous lines of travel from tree to tree, or into your home. There is a wealth of great information on carpenter ants in the Pacific Northwest. Click here to see some of the numerous articles we’ve written about them and the damage they can do.
These rodents can be a real problem in the Spring and Summer, but are active in the Fall and, though activity is sparse, still operate here and there in the Winter. As larder hoarders, they store up food to help them survive the freeze, but they’ll still make gopher mounds in your yard if they feel up to some exercise. We’ve got a great article (with video) on gopher behavior and traits here.
Like gophers, moles slow down in the Winter, but have no difficulty surviving it and will still make occasional mounds in yards. They’re insectivores and tend to tunnel closer to the surface than gophers. We’ve even seen them pushing up mounds in the snow! Pest expectancy: Anytime, but more prevalent in the warmer months. Check out our informative research on moles and some control methods here.
Well, they’re horrible. We know that and we’re sure you already know that, too. They feed off of you when you sleep, breed in your bed, multiply rapidly, and have no season. Pest expectancy: Always and forever. They can drain your blood any night of the week, any week of the year. Trust us, you do not want them in your home. Bedbug infestations can spiral out of control rapidly. Here’s some important information about bedbugs that can help you not only identify them, but understand what they’re doing and why.
Usually brought in on pets, fleas are an annoyance and can spread quite quickly. Flea bites itch and are usually quite visible to others, letting people know about your embarrassing problem at home. They have some of the strongest and most durable eggs around, and those eggs can survive a number of conditions the adults or other insects cannot. They operate year round, but adults don’t handle cold well at all. Luckily for them, your house isn’t cold. Moreover, your pets (and you) are quite warm and tasty to them.

These little monsters are somewhat like a cross between a bedbug and a spider. We know, that’s a nightmare. Ticks are arachnids, like spiders, but are more closely related to mites. They drill their head into your skin and drink up your blood. This is a Saturday night out for them. They then use your blood to mate. Fun stuff. Lucky for us, ticks have two distinctive swarms/cycles per year, and are largely dormant at other times. They have a Spring rush, and another in the Fall, though both are fairly brief. To learn more about ticks (and to give yourself the shivers), try the always-informative CDC database.
Nuisances extraordinaire. Flies are perhaps one of the most common pests we encounter, and are one of the most agitating. Buzzing around your head. Landing on your plate. Walking across the television while you’re trying to watch a season finale. Touching down on your arm and then taking flight before you can react. Crawling on your baby’s face. It’s almost as if flies are purposely trying to make us despise them. Check out some great information on types of Pacific Northwest flies here.
