WHY DO ANTS COME IN MY HOUSE WHEN IT RAINS?

By Planet Friendly Pest Control·2 min read

Ants are one of the most universally-distributed pests in the world (except Antarctica). They tend to rush indoors—often immediately after rainfall. You are not imagining things if you've observed more ants in your home after the rain. Here's why this happens and how to prevent it.

01

Why Do Ants Come Inside When It Rains?

Rain drives ants indoors for survival. Here's why you may see ants after a storm:

  • Flooded Nests - Heavy rain floods underground nests, forcing ants to seek dry, sheltered spaces—like your home
  • Moisture and Humidity - Ants thrive in damp environments. Post-rain humidity and your home's warmth make an ideal environment.
  • Easy Entry Points - Ants easily locate cracks, gaps, or weak points in your home to gain access.
02

How to Get Rid of Ants After Rain

  • Identify Entry Points - Trace the ant trails to locate where they're entering. Seal cracks and gaps in walls, windows, and foundations.
  • Create Barriers - Use natural repellents like vinegar, lemon juice, or citrus peels at entry points. For severe infestations, consider sprays or powders.
  • Use Ant Bait Traps - Place traps along ant trails to eliminate colonies at the source. Keep these traps out of reach of pets and children.
  • Clean Thoroughly - Remove crumbs and spills, wipe surfaces, and empty trash bins regularly to reduce attractants.
03

Should You Call an Ant Exterminator?

If ants persist, it's time to call a professional. Here's what they provide:

  • Professional-grade treatments to remove ants.
  • Inspections to identify entry points and risks.
  • Long-term solutions like termite prevention to keep pests away.

    Alex was great! Very professional and explained the whole process before doing any work. We had a wasp nest in our wall, getting in through a seam between our brick and siding. I thought it would be a costly problem, but it was taken care of in about 15 minutes.

    I am very pleased with the work of Planet Friendly Pest Control. I had a large wasp nest in the garage and they came out to treat it the same day! The process was clear and professional. I was told the price when I called and they didn't try to upsell me on a monthly or quarterly contract. As mentioned above, they came out the same day I called and they texted me when they were on their way. They treated the nest and then came back a week later to confirm it was taken care of and removed the nest. It's now been a couple of weeks since the initial visit and no sign of new wasps! I would not hesitate to use them again.

    I want to sincerely thank Planet Friendly Pest Control and its owner, Gene Wright, for their immediate response and action to deal with a hive of Bald Face Hornets who, unbeknownst to me, had taken home in a fair size shrub at the back of my house. As I attempted to trim the shrub, I was swarmed by Hornets and stung 8 or 9 times before I could get to safety. I left my tractor and tools in a hurry and was afraid to retrieve them until the bee issue was addressed. Again, PFPC responded quickly and allowed me to get my tools and continue my recovery from the bee stings. I considered the price to be very fair for the treatment of the issue at hand and the sharing of knowledge to avoid further such mishaps. I will only call PFPC when in need of pest control.

    Really appreciate Roger coming out to the house to not only treat for common insects that like to make their way into the house (regularly scheduled maintenance), but also exterminate a hornet nest we found on our deck this last week. Great service, arrives on schedule (and sends a text with arrival time when he’s on his way), and most importantly - no critters coming inside my house - or hornets potentially stinging us. Recommend Planet Friendly Pest Control to anyone looking for an exterminator.

    Gene Wright came highly recommended by multiple neighbors. He came out the same day I called and showed great knowledge about our mouse problem! Gene was responsible, knowledgeable and a delight to deal with. We highly recommend Planet Friendly Pest Control.
