How to Get Rid of Ants

Instant versus delayed reaction 

Ant killers that work instantly are good for removing ants that appear in the kitchen or similar places where they are unsightly. The disadvantage is that you only kill the ants you can see; there may still be ants under the floorboards and in the walls that will come out after a little while. If the ant killer remains in place it will act as a deterrent, but it won’t stop ants from appearing in other parts of your house. 

Delayed reaction ant killers will take some time to work, but they remove all ants from home. It typically takes a couple of days to kill a colony of ants. Delayed reaction poisons don’t act as a repellent, and in some cases, a new ant colony can move in if the old one dies off. 

Ant Killer Versatility

Some ant killers are good for a wide variety of insects that can appear in the home. This can be useful for pest control if you don’t want to purchase too many different products, but if your ant problem is persistent then it is best to get a specialised product suited to your unique circumstances.  

Other measures for Killing Ants

To get the best results, there are a few things you can do after the ants are gone:

● Ants are drawn to food. Keep food scraps off the kitchen floor and pet food away from patios and verandas where it will attract ants.

● Avoid leaving water bowls outside. Ants need water and will be drawn to it.

● Seal any cracks around windows and sinks and the bathtub where ants may be getting in.

● Trim back vegetation away from the house as this is one of the main ways ants use to enter a home.


Remember that most ant killing solutions require the use of strong and dangerous chemicals. Ensure you use appropriate protective wear when handling the product and take precautions to ensure no children or pets come into contact with it.
