The Contributing Factors To Their Increased Presence

Why You're Seeing More Pests During Summer?

Have you ever wondered why pests are more active in the summer? In this article, the experts at Pro Pest Control Sydney point out some interesting reasons. In Australia, the climate can be very warm. Since we’re below the equator, you can expect summers to be very hot.

You could be in the outback where the temperatures will exceed 30 degrees (Celcius). In more urbanised areas, it can still be warm in the summertime. The summer months in Australia range from December to February.

During these months, you can expect pests to be more active based on the following factors listed below. Let’s get started.

1. Higher Temperatures

On average, the summer temperatures will depend on the region of Australia you’re in. In Adelaide, you can expect maximum temperatures to reach 29 degrees (Celcius). The temperatures in South Australia on the low end will be approximately 17 degrees (Celcius).

Most of the pests will operate in temperatures that are quite warm. However, some of the pests such as spiders will move around during the night time. Coupled with humidity, it can also be a great place for many pests to be out and about.

2. Increased Food Source

During the summer months, you will see plenty of food sources for pests. Some pests will eat food scraps, rubbish, and other materials. There are a few pests that will eat other animals as well.

Spiders can eat flies and other insects that can get trapped within their webs. Likewise, rats and mice will find food outside of your home or in urbanized areas where rubbish is present. Also, crops will be plentiful during the warmer months, which will be inviting for many pests.

If untreated regularly, crops can get damaged due to the pests feeding off of them.

Food Sources For Pests

3. Increased Moisture

With summer weather, there is a chance for increased moisture. Humidity is perfect for not only pests to move around and hang out, but it’s also great for them because there is food that will be out and about in the form of small insects and other prey.

If the weather is hot and humid, you might hate it. But the pest themselves will love it. They cannot get enough of it and will find a place that matches such conditions.

For this reason, they may gain entry into your home and find a place that is warm and moist. That’s why you need to ensure that you take preventative measures to keep them out.

4. Life Cycles of Pests

The pests you will encounter will usually be cold-blooded. Because of that, the climate will affect them greatly. Their life cycle will mostly occur during the summer months where they are most active.

The development of newer pests may also occur during the summer months. For example, ants can increase in size and reproduce over the course of the summer season. By the time the weather gets cooler, the ant colony will grow larger in size.

Plus, they will spend a bit of time preparing for the winter months.

Life Cycles of Pests

5. Increased Number of People And Activity

Even if you have sealed off any entry points in your home where pests can get in, infestations can happen. How does this happen? Many pests can ‘hitch a ride’ on many objects.

They can cling onto clothes, grocery bags, packages, and more. The more people are out and about, the more opportunities are presented to pests from getting inside your house. Even with the small crevices and cracks are sealed off, pests can sneak into your home while the windows and doors are open.

People will be opening their doors and windows constantly. As long as you have screens up in your windows, pests can get in (especially spiders). Before going outdoors, you want to plan ahead.

This includes knowing what kind of clothes to wear and applying insect repellent. Many pests will not be attracted to the ingredients of insect repellent. These include fleas, ticks, spiders, and other insect-related pests.

If you are going into an area where ticks are known to be present, you want to wear long-sleeved clothing. Yes, wearing long sleeves in the summer may not be the best idea. However, it may be your best protection against tick infestations.


The warmer months will be the perfect time for pests to move around. Before the summer months, you want to make sure that your home does not provide any entry points for pests looking to migrate before the weather gets worse. Seal the crevices and cracks outside of your home.

Also, be sure to reduce the amount of food sources that pests enjoy. Take the necessary precautions and ensure that you don’t allow pests any easy opportunities to enter your home. Inspect anything you bring in from the outside closely so you don’t accidentally infest your home with pests.
