The Effects of Rain on Ants

Rain can have a massive impact on the behavior of ants. Heavy rains can flood ant nests and cause them to relocate in search of dry ground. As they look for new places to live, they may stumble upon your house and decide to make it their new home.

In addition, rain can wash away the food sources that ants rely on for survival. This forces them to look elsewhere for sustenance, which could lead them into your home in search of food scraps or other edible items.

How To Protect Your Home From Ants After Rain

If you want to protect your home from an ant infestation after heavy rain, there are several steps you can take:

  • Seal any cracks or crevices around windows and doors where ants can enter your home.
  • Clean up any food crumbs or spills that may attract ants inside your house.
  • Combine equal parts of thyme, peppermint, and lemongrass essential oils in a spray bottle and spritz areas where ants typically enter your home. The pungent smell can deter ants.
  • Have an exterminator apply pest control treatments indoors and outdoors to eliminate existing ant colonies before they invade your home.

If you notice ant mounds popping up in your yard after heavy rains, contact a professional pest control company to help eliminate them quickly and safely.


Ants are resourceful creatures who will do whatever it takes to survive—including invading homes after heavy rains wash away their food sources and flood their nests. With the assistance of our pest experts at Spidexx Pest Control, you can help protect your home from ant infestations after rain and year-round.
