Why Do Pests Become More Active in Summer?

The Summer Surge: Understanding Increased Pest Activity

Ever wondered why pests are more active during the warmer months?

It seems like as soon as that warm weather rolls in, all sorts of creepy crawlies start popping up.

But don’t worry, our team of professionals at Pro Pest Control Perth got some answers for you.

Let’s take a closer look at why pests love to come out and play during those hot summer seasons.

Factors Contributing to Pest Activity in Summer

High Temperatures

First things first, let’s talk about temperature. As the mercury rises, so does summer pest activity. Just like us humans, bugs prefer warmer climates too. They thrive in temperatures above 70 degrees Fahrenheit. So when the warmer temperature kicks into full gear, stinging insects and other pest infestations get their party hats on and come out to join in the fun.

Increased Food Source

During hot weather, we tend to leave our windows and doors open more often to enjoy that refreshing breeze. This also provides easy access for insects looking for something tasty inside your home. Plus, with more barbeques and picnics happening outside, crumbs and food scraps become an inviting feast for these unwanted guests.

Increased Moisture

Extreme heat isn’t the only thing that attracts pest population to your home during summer showers. It’s also the increased moisture levels. Bugs are incredibly resourceful and can detect even the slightest hint of water from miles away. When there’s a spike in humidity or if rain showers bless us a little too frequently, it creates perfect breeding conditions for insects.

Increased outdoor activities

Summer means more time spent outdoors. With more outdoor activities such as garden parties, barbeques, camping trips, person-to-person interaction, and picnics, an increase in the availability of food for pests is inevitable. This also causes an increase in pest activity and increases the chances of pests entering your house indoors through open doors and windows. With increased trash from these outdoor activities also come pesky flies, maggots, and cockroaches that will want to feed on these leftovers.

More Reproduction

The warm temperatures create ideal conditions for many pests to reproduce at a much faster rate. Summer is the perfect breeding period for many pest species as their body temperature increases. Also, they are able to lay eggs faster leading to increased pest activity and longer life cycle during this season.


What types of pests are most active during the summer?

Mosquitoes, ants, termites, and flies are the most common pests you’ll encounter during the hot summer months.

How can I prevent mosquitoes from ruining my outdoor activities?

To keep mosquitoes at bay, remove any standing water around your home, use mosquito repellents or citronella candles, and wear protective clothing.

What can I do to get rid of annoying ants in my kitchen?

Seal off entry points, keep food sealed tightly in containers, and clean up spills promptly. Also, consider using natural ant deterrents like white vinegar or peppermint oil.


Pest activity is more common during the summer months mainly due to an increase in temperature and humidity.

The key is to be proactive in pest prevention by using physical barriers, properly disposing of garbage cans regularly, removing standing water from areas around your property, and inspecting your home for potential entry points.
