Salt to Kill Ants
Using salt to kill ants may be a good option, but you should use it in large amounts. You will also need to make sure to clean up the area afterward.
Salt dehydrates many insects and other creatures. In some cases, it even affects the exoskeleton of certain insect pests. It can also dry out snails and slugs.
Several different types of salt have different properties, and there are some that may damage ant exoskeletons. Other types of salt are not as effective.
The most effective way to use salt to kill ants is to make a salt barrier. The barrier should be at least one inch tall and should be poured directly into the ant nest.
You can also combine salt with boiling water. This solution can be poured into a spray bottle. You can also use salt and vinegar. You may find that you will need to repeat the process several times to kill ants.
You may also want to use a salt barrier if you have an ant infestation in your yard or garden. Salt can dehydrate many ants, and you may find that they will eventually move on to another route. If you have a heavy infestation, you may need to repeat the process several times to get rid of ants.
One experiment offered ants a choice between sugar and salt. The results showed that carpenter ants preferred the salt solution. It was also found that ants living more than 60 miles inland preferred the salt solution over the sugar solution. The researchers are now examining whether this preference applies to all insects.
