A fire ant bite can be very painful.

Fire ants are aggressive ants that are known to group together and attack anyone or anything that disturbs their home. This often results in bites to both animals and people. The bites can be quite painful. If your home or yard is invaded by these pests, you will want to control the infestation as quickly as possible to avoid bites to unsuspecting humans and pets. You could choose a commercial ant treatment, but these can be expensive. The other option is to make your own home remedy to effectively get rid of the ants for far less money.

Method One

Step 1

Place a cup of bath cleaner containing bleach into a spray bottle. Place the lid on the bottle.

Step 2

Spray the cleaner directly onto fire ants you find in your home on hardwood or linoleum floors. Also spray it around any entry points the ants are using to get into your home. Do not spray it on carpeting as it will bleach your carpets. It also can be sprayed outside your home around the foundation.

Step 3

Allow the cleaner to sit for several minutes to kill the ants. Use a mop to clean the sprayed area.

Method Two

Step 1

Purchase worm castings from a garden supply store or online merchant. Worm castings are worm feces. It contains a chemical called chitinase that destroys the exoskeleton of fire ants.

Step 2

Sprinkle the worm castings around plants and onto the anthills.

Step 3

Reapply more castings every 10 weeks.

Method Three

Step 1

Boil three gallons of water in a large stock pot.

Step 2

Wear work gloves and dig a small hole into the top of the top of the fire ant hill. Use caution to keep ants off of your skin.

Step 3

Pour the boiling water down the hole to scald and kill the fire ants. Use caution pouring the water to avoid burning yourself.

Step 4

Repeat as necessary. If the first treatment does not kill the queen, the colony may move to another place in your yard. If this happens, repeat the process.


Boiling water will kill any ants it comes in contact with; however, it may also kill the grass in that area and it may not grow back.

Avoid using treatments on other types of ants. Other species of ants can help keep the fire ant population under control. Focus on areas where the fire ants are specifically.

Be aware when using any treatment method. Since fire ants are known to swarm when they feel threatened, they will likely try and attack you. Be prepared to move out of their way if swarming begins. Also, wear long pants, socks and close toed shoes to protect yourself.
