Can Chalk Get Rid of Ants?

Have you ever picked up a chalk to try and draw a line on surfaces you’ve spotted with ants crawling about, chances are you already believing that a simple line of chalk can remove ants away from your premises.

Answer this question before reading on:

Does drawing a line of chalk near the ant hole or along the ant trail useful in:

  1. Keeping the ants away
  2. Killing the ants
  3. Temporarily derailing an ant trial
  4. All of the above
Fire ants can cause painful and stinging bites

Is chalk an effective remedy against ants?

An old wives tales, many of you would have chosen some answers which ‘keep the ants away’ and ‘killing ant’. This is false and chalk itself would not work to eliminate ants completely. While the drawn line of thick chalk can temporarily derail an ant trial, making the colony confused with the scents. However these ants soon establish their scents and the trail can come back at work again.   

While derailing an ant trail may seem like the ants are being kept away, these ants are definitely not killed. They are only temporarily shifted away from the original site as they avoid the chalk line.

This is the same as with any other things which disrupt the scent trails i.e. water. These DIY methods are not effective in getting rid of ants.

Why are natural ant control remedies ineffective?

Firstly, ants hide and build their nests at quiet and hard to spot locations that increase the detection challenges. Secondly, most remedies merely mask the chemical signs or known as pheromones and temporary confuse ants’ direction for a short while. Thirdly, we may only target and localise the treatment area instead of eliminating the root source. Fourthly, as non-professionals, we have the tendency to apply at the wrong location or inadequate frequency. In addition, most off-the-shelve solutions may have less efficacy in terms of dosage level and quality. Above all, ants infestations will continue building without a sound cleaning regime and proper ants treatment in place.
