Why Are Pests More Active In Summer?

Summer is a fun season for people because the weather is warm and the skies are blue. On a clear day, you could look around in any direction and see beauty somewhere. Australia has no shortage of beautiful beaches for people to spend their time. You could gaze into the ocean waters and get lost by staring at the horizon.

Do you ever notice how pests seem to be more active in the summertime too? Pests come out of their nests in the summer for the same reasons why people come out of their homes and go outside. It is a time when the environmental conditions make it easier for them to be more active and productive. Pests are able to grow faster, seek food more easily, and increase their numbers if the right temperatures and levels of moisture are present.

Let’s explore the top 6 reasons why pests are more active in the summer.


1) More Food Sources

 All lifeforms seem to come out in the summertime. You will see rats, flies, spiders, snakes, moths, cockroaches, lizards, mosquitoes, ants, and termites. With all these insects, rodents, and reptiles roaming around, it creates more opportunities for these creatures to find food sources.

For instance, if there are more rodents roaming around, such as rats and mice, then snakes are going to find more food for themselves. If more flies buzz around in the air, then spiders are likely going to capture more of them in their webs. So basically, all these pests turn on each other by coming out together at the same time.

Summer is the time when food sources are available to humans too. If you were to grow your own crops in a field or garden, then the time between May and September would be the time to harvest them. Fruits and vegetables grow throughout the springtime and become fully matured at some point during the summer. That is when people pick their fruits and vegetables for consumption or resale.

However, humans are not the only ones to eat this food. Rodents and certain insects love to inhabit gardens and eat the foods that come from your crops. That is why farmers spray a pesticide solution on their crops because they want to keep pests away from them.


2) Warmer Temperatures

 Most pests hibernate during the winter because the air is too dry for them to survive. There is also a lack of insects and other food sources for them to eat. So, they stay underground in their warm nests until the colder winter temperatures go away.

By the time spring and summer come along, pests are ready to wake up and begin their mating, growing, and eating cycle all over again. The warmer temperatures enable this cycle because of the abundance of moisture and food sources that are present outside.


3) Increased Moisture

 No lifeform can survive without water or moisture. All pests need water or moist environments in order to sustain their life cycle. Warm air is able to carry a higher level of water vapor compared to cold air. This water vapor is also known as moisture or humidity.

The pests that benefit the most from moisture are mosquitoes and flies. That is why swampy environments that are hot and humid tend to have mosquitoes and flies flying around the most. Moisture creates better living conditions for pests, which allows them to harvest food, consume water, and create more life.


4) Increased Daylight

 The summer daytime hours are longer than the winter daytime hours. This means the warmth and light outside will last longer. As a result, pests have more time to find food, build nests, and feast on organic materials. And since you and your pets are going outside more often, you’ll likely carry more ticks and fleas inside your home without even realizing it.


5) More Reproduction

 After a long season of hibernation, pests are ready to get busy again by reproducing and increasing their numbers. They spent so many months being dormant that they have to forage for food and restock their colonies and nests with it. As reproduction takes place and new hatchlings emerge from eggs, the soldier pests have the job of keeping them fed. That is why they’re so actively searching for food in the summertime.

Of course, the role of “soldier” typically applies to ants and cockroaches. Two other pests that actively reproduce in the summer are flies and rodents. Since mammals like to go outside in the summer and release faeces onto the ground, flies will find plenty of places to feast and lay their eggs. Rodents also increase their numbers because they feast on plant matter the most. Since plants and trees regrow their leaves, that means rodents have the opportunity to feast on grass, twigs, seeds, and grains.


6) More People

 People and other warm-blooded mammals like to go outside during the summer. This means certain pests, such as mosquitoes and ticks, will want to feed on all this warm blood. Your dogs and cats will become infested with fleas and ticks, while the mosquitoes in the air will look for every opportunity to bite your naked skin and suck blood from underneath it.

Termites Summer Pest


Believe it or not, a lot of pests would prefer to stay in an air-conditioned environment rather than face the extreme heat of the outdoors. A warm environment is one thing, but a dreadfully hot environment is another.

Pests like to be comfortable just like humans do. That is why several types of pests will make their way into your house in order to seek this comfort. The main pests you may find inside your home during the summer are rodents, cockroaches, termites, ants, and spiders.

All you can do is take the necessary precautions to avoid having issues with these pests during the summer. Make sure you have a pest control technician who regularly sprays around your property and inspects the walls and structure for signs of infestation. You should also spray some bug repellent on your wrists if you plan to stay outside for extended periods of time.
