Made this natural ant killer that is safe for indoor use and safe for your pets! DIY natural ant killer is easily made from ingredients you probably already have at home. You’ll just need a spray bottle and you’re all ready to make your homemade ant killer.

Did you know here are over 22,000 species of ants? These ant species include banded sugar ants, yellow crazy ants, and European fire ants to name a few. While, like most insects, ants can be beneficial, they can be quite destructive in your home or at your picnic. They sneak into your home raiding foods in the cupboard, ruining indoor structures, and even biting us.  Let’s focus on making an indoor ant killer that is natural and safe to use around pets.

It can be a challenge to eliminate a colony of ants, especially during the summer season where they tend to collect their food for future use during the rainy season. They are currently so desperate for water in this Southern summer heat that they are all over the ridge of the kids’ pool!

However, it is possible to eliminate them using either chemical, biological. or physical DIY ant killers We try to avoid using avoid using harmful chemicals in our home, especially since we have kids and a dog, so we prefer using natural ant killer when possible.

In this tutorial, I’ll show you how to make a homemade ant killer that is safe, organic and effective. This DIY ant killer works well as an indoor ant killer, but if you have these pests outdoors you’ll need something stronger. And if you have fire ants in your yard like we have all over Alabama lawns? May God have mercy on you. They are the worst. Anyway, let’s focus on our natural ant killer for indoor use. Talk of fire ants gives me nightmares.

Indoor Ant Killer Tips

If your homemade ant spray keeps getting clogged here are a few options to help:

  • Make sure you’re using powdered black pepper. Ground pepper flakes are pictured and worked fine for me but I’ve received multiple comments from users who experienced a stopped-up spray bottle when using the flakes.
  • If you’re still getting clogs, try switching to a larger spray bottle. Dollar Tree carries spray bottles that are more of the standard cleaning spray size. You can still make a small batch but the spray hose will be larger in diameter with the bigger bottle
  • If all else fails, try using some black pepper essential oil.
