pest seasons

When do pests come out to play?

Like the leaves falling off the trees at autumn without fail each year, pests also have a favourite time they like to rear their heads and infest our homes and businesses. No matter the time of year, there is always at least one species of pest just itching to gain access to your property.

Luckily, as pests are creatures of habit, it is easy to predict when they are gearing up to invade your home and/or business.

Read our guide to help you plan ahead and proof your property against future pest infestations.

Spring

Spring time marks the start of new beginnings. However, there are also a handful of pests which like to become a nuisance in your homes and businesses.

Common spring pests:

  • Termites
  • Clothes moths
  • Pigeons
  • Cockroaches

Termites

Spring time marks the start of termite season. This is when the winged alates leave the nest to mate and start new colonies.This is often referred to as swarming. Termites usually start to swarm when the weather is warm, just after it has rained.

Clothes moths

Clothes moth adults start to emerge during the spring and begin to breed.

Did you know, it’s actually the larvae which feed on the fibres in fabric and clothing and cause damage, rather than the adults?

Pigeons

Pigeons can become a problem too, as spring marks the start of their mating season.

An increase in pigeon populations in urban areas can result in a buildup of faeces, which in turn can result in the spread of diseases.

Other spring pests

You might start to notice ants in the garden again, as well as flies and some stinging insects. Cockroaches can also start to appear and due to the increase in travel over Easter and during school holidays, bed bugs can also be a problem. If spring time is unusually cold, rats and mice might still cause issues for homeowners and businesses.

Summer

Unfortunately, it’s not just you that enjoys the longer days and warmer weather, a handful of pests also relish the summer months.

Common summer pests:

  • Mosquitoes
  • Stinging Insects
  • Cockroaches
  • Ants
  • Flies

Mosquitoes

Mosquitoes are arguably the most common summer pest, delivering annoying itchy bites to numerous people world wide.

The reason behind these biting insects being so common during the warmer months? The high temperature enables them to complete their life cycle faster, resulting in more eggs being laid.

Stinging insects

Stinging insects such as bees, wasps and hornets can be a big problem during the warmer months. Although their season starts during the spring, it is during the summer when their population reaches high numbers.

Cockroaches

Cockroaches are a common pest found all year round. Their presence can vary depending on the species and the weather. Summertime is peak breeding season and, like rodents, they often migrate indoors during the winter to escape the cold.

Cockroach infestations can be a huge concern for home and businesses owners alike, as not only do they spread food-borne illnesses, but they can also trigger asthma and other allergies.

Ants

Like stinging insects, the ant season starts during the spring, however, it is during the summer when they become a problem. Like termites, ants will swarm in order to breed and start new colonies. This is why flying ants are typically seen in July.

Flies

Flies can be a big nuisance in homes and for businesses like restaurants and cafes. Due to their breeding habits, flies can be found in large numbers during the summer months and can aid the spread of certain diseases.

Other summer pests

Summer is generally seen as peak holiday season. The increase in travel and time spent in hotels can lead to the spread of bed bugs. Birds are also active throughout the summer months and due to the increase in temperature, fleas could become a problem too, especially for pet owners. Rodents such as field mice can be a concern for businesses in the food industry causing damage to crops and raw produce.

Autumn

As the weather gets colder, a couple of different pests will try to get indoors to find shelter, warmth and food, causing problems for homes and businesses.

Common autumn pests

  • Stink bugs
  • Spiders
  • Bed bugs
  • Fleas

Stink bugs

Stink bugs get their name from their tendency to eject an extremely foul and strong smelling fluid. This acts as a defence mechanism for the insect, as it releases this odour when it is threatened.

They can also be a big concern for businesses in the food industry – stink bugs are regarded as a serious agricultural pest, causing damage to crops across the Eastern United States.

Spiders

As the autumn time approaches, many spiders tend to migrate into our homes and businesses – this can be a real problem, especially if you have arachnophobia! This movement is a result of breeding habits, as many male spiders become mature around this time and go on the hunt for a mate.

Fleas

Fleas flourish in warmer temperatures, as the temperature drops they can be found infesting homes in search of warmth and food. These insects can be a big concern for homeowners, particularly when pets are present, due to their biting habits.

Bed bugs

Bed bugs can be found all year round, but the number of infestations often soar during the summer and autumn periods due to the increase in travel for holidays and weekend breaks.

Hotels and other overnight accommodation facilities play a large role in the spread of bed bugs due to the high number of customers they receive. This allows bed bugs to easily hitch a ride in your luggage back to your home.

Other autumn pests

Depending on the weather, stinging insects such as wasps and bees can often remain active during the early stages of autumn. Both cockroaches and rodents can start to migrate indoors to escape the cold.

Winter

There are a couple of pests which seek refuge in your homes and businesses during the winter months to escape the cold and find food.

Common winter pests

  • Rats
  • Mice

Rats

During the winter, rats will enter homes and businesses to find shelter, warmth and food. This can result in a range of damage to your property. A study by Rentokil discovered that rats are the most destructive pests for businesses, causing damages to electrical equipment resulting in machine and production downtime.

Mice

Like most rodents, mice like to migrate indoors during the winter for shelter and food. Their presence in your property can result in a range of damage due to their gnawing habits, and could also lead to the food contamination.

Other winter pests

Travel during the holiday season can assist in the spread of bed bugs. Fleas can also be found infesting homes to escape the cold, as well as cockroaches.
