Seasonal Pests: Which are Most Common in What Months? (2024)

FAQs

What season are pests most active? ›

As temperatures rise each year in the spring and summer, the warmer temperatures will likely attract more insects that were not active in the cooler months. Increased rainfall in the spring and summer months also contributes to increased pest activity.

At around 45 degrees, insects start to stir, but it isn't until around 70 degrees Fahrenheit that they are at full strength. At 70+, they can reproduce in large numbers and turn into an infestation before you know it. The issues start from March to April, but they usually get worse around July and August.

A: Generally speaking, when the temperatures go up—the bugs come out. It's when they're harboraging for food and looking for moisture. When the temperatures go down most of your insects go down, so bugs are more active in the summertime.

Summer is prime-time for insects. Warmer weather provides perfect conditions for pests to prosper. Ticks and fleas are two parasites that are plentiful during the summer months. With more lush greenery and food readily available, these hitchhikers will latch on to humans and animals alike.

Each season brings unique pest activity. Some pests are more active in the warmer months of spring and summer, while other pests become more noticeable when they come in from the cold of fall and winter. Regardless of the season, Adam's has the right pest control and prevention plan for you.

The best time for pest control in your residential and commercial buildings is in early spring. Spraying in spring allows you to destroy the pests' nests when their numbers are low. Given the low number of pest colonies and nests, the treatment will be more effective and long-lasting.

But did you know that pest infestations might be worse in the fall and winter than they are in the summer? Many bugs are built to endure the cold, even if they thrive in the scorching spring and summer heat.

Key Takeaways. Due to climate change and global warming, pest populations are increasing, and people in and around Northern California (and around the globe) are seeing more bugs and pests during the summer months.

Not many insects are active in the winter, but the nymphs of dragonflies, mayflies and stoneflies live in waters of ponds and streams, often beneath ice. They feed actively and grow all winter to emerge as adults in early spring. Overwintering as Eggs. Lesser numbers of insects lay eggs which survive the winter.

Mosquitoes in the United States tend to have higher activity levels during the hours before sunset. If you plan on enjoying the great outdoors during the evening, especially in wooded, shady areas near standing water, you will want to make sure you have extra protection on hand and ready to go to prevent insect bites.

What weather attracts bugs? ›

HOT WEATHER

With the exception of the tropics, insect reproductive rates typically increase in warmer months, which is why you see more bugs when the temperature rises. As temperatures increase, so do the metabolic rates of insects, which means they need to eat more to survive.

co*ckroaches are more active when it's warm outside

During the summer months, co*ckroaches are more active, searching for food, water, and shelter. As a result, they often find a way inside homes through cracks, gaps, and other openings on the exterior.

Roaches are resilient and extremely hard to get rid of once they have established themselves in your home. As long as the temperature indoors is above 50 degrees, roaches can remain active year-round, although they are more prevalent in the spring and summer months.

In most US states with colder temperatures during the winter, bugs have adapted ways to survive the colder temperatures. At temperatures below 45 degrees, most insects become inactive.

co*ckroaches become more active in late spring and early summer, as cold blood insects generally thrive in warm and humid weather. The warmer it is, the more active they are, UC Davis entomologist Lynn Kimsey said. Stumbling upon the lengthy, flattened insect at home tends to incite feelings of disgust and fear.

Because insects are cold blooded, the environment regulates their body temperature. In hot weather, bugs are much more active. Larvae grow faster, insect's speed increases and mating peaks. As the insects strengthen their numbers, keeping them off and out all summer long can be a challenge.

Fall and winter

As both the temperature and the leaves start to fall, bugs begin searching for a cozy place to ride out the winter months. These critters are looking for food, shelter, and warmth, and your home just so happens to be the perfect accommodation.
