Friday FAQ: Why Does Increased Rainfall Lead to More Pest Problems?

Hello, Paragon Pest Control community! 🌧️🏡 Welcome to another edition of our Friday FAQ series. Today, we're diving into a question we often get asked during the rainy season: Why does increased rainfall lead to more pest problems? Let's explore the reasons behind this phenomenon and share some expert tips on how to keep your home pest-free, even when the weather doesn't cooperate.

How Rainfall Affects Pest Behavior

When it rains, it pours...pests into your home! Here's how increased rainfall impacts various types of pests:

  1. Increased Shelter-Seeking Behavior

    • Why It Happens: Just like us, pests seek shelter from the elements. When their natural habitats get flooded, they look for dry, safe places to stay, often finding their way into our homes.

    • Common Culprits: Ants, spiders, and rodents are notorious for seeking refuge indoors during heavy rains.

  2. Breeding Grounds Galore

    • Why It Happens: Standing water from rainfall creates perfect breeding conditions for many pests, especially mosquitoes. More water means more places for them to lay their eggs.

    • Common Culprits: Mosquitoes, flies, and other water-loving insects thrive after rainstorms.

  3. Disrupted Food Sources

    • Why It Happens: Rain can wash away food sources for pests in their natural habitats, forcing them to move closer to human homes in search of sustenance.

    • Common Culprits: Rodents, cockroaches, and ants are particularly driven indoors by the search for food.

Expert Tips to Keep Pests at Bay

Here are some practical steps you can take to minimize the risk of a pest invasion during rainy weather:

  1. Seal Entry Points

    • What to Do: Inspect your home for any gaps, cracks, or holes that pests could use to enter. Seal them with caulk or weather stripping.

    • Tip: Pay special attention to doors, windows, and the foundation of your home.

  2. Eliminate Standing Water

    • What to Do: Regularly check your property for areas where water might collect and become stagnant. This includes gutters, bird baths, and plant saucers.

    • Tip: Ensure your yard has proper drainage to prevent water accumulation.

  3. Maintain Your Yard

    • What to Do: Keep your lawn mowed, and trim bushes and trees to reduce the number of hiding spots for pests. Remove any debris or clutter that could harbor insects or rodents.

    • Tip: Consider using pest-resistant plants in your garden.

  4. Regular Pest Control Treatments

    • What to Do: Schedule regular pest control treatments with Paragon Pest Control to keep pests at bay, rain or shine.

    • Tip: Our General Pest Quarterly Plan is a great way to ensure year-round protection.
