How Hot Weather Affects Pests: What You Need to Know


As temperatures rise, so does the activity of various pests. While summer brings warmth and sunshine, it also brings an increase in the number of unwanted guests in and around our homes. Understanding how hot weather affects pests can help you take proactive steps to keep your living spaces pest-free. Here’s what you need to know about the relationship between heat and pest activity.


  1. Increased Pest Activity

Warm weather accelerates the life cycles of many pests, leading to a rapid increase in their populations. Insects such as ants, mosquitoes, and flies thrive in the heat, which boosts their metabolism and reproductive rates. This means you may notice more pests than usual as temperatures soar.

Ants are particularly active during hot weather. They search for food and water, often invading homes in large numbers. Mosquitoes also breed more rapidly in warm conditions, taking advantage of any standing water to lay their eggs. Consequently, mosquito bites and the diseases they can carry, such as West Nile virus and Zika virus, become more prevalent.


  1. Pests Seeking Water

Hot weather often leads to dry conditions, causing pests to search for water. This can drive them into homes in search of hydration. Common culprits include rodents, and spiders. Leaky faucets, pet water bowls, and even condensation from air conditioners can attract these pests.


  1. Heat Drives Pests Indoors

As outside temperatures become unbearable, many pests seek refuge indoors where it’s cooler. This is especially true for spiders and wasps. Attics, basements, and crawl spaces provide ideal shelters for these pests to escape the heat.

Spiders often look for cooler, darker places to build their webs, and wasps might construct nests in attics or under eaves. 


  1. Increased Food Sources

Summer brings not only higher temperatures but also more outdoor activities and food consumption, such as barbecues and picnics. This abundance of food attracts pests like flies, bees, and ants. Proper food storage and waste management are crucial during hot weather to prevent these pests from becoming a nuisance.

Flies are particularly attracted to food and waste, and they can rapidly become a major annoyance. Ensuring that food is covered and waste is promptly disposed of can help minimise their presence.


Proactive Pest Control Measures

To combat the surge in pest activity during hot weather, consider the following tips:

  1. Seal Entry Points: Inspect your home for cracks and gaps where pests might enter and seal them with caulk or weather stripping.
  2. Eliminate Standing Water: Regularly check for and remove standing water to reduce mosquito breeding sites.
  3. Proper Food Storage:Keep food in sealed containers and clean up spills promptly to avoid attracting pests.
  4. Regular Inspections:Conduct regular inspections of your home and property for signs of pest activity and address any issues immediately.
  5. Professional Pest Control: Contact a pest control professional for regular treatments and inspections to keep your home pest-free.
