Ant season is well and truly here, and these pesky insects seem to find their way into a home through every single nook and cranny. For most of us, using chemicals to deter them, particularly in the kitchen, is simply not an option. So, how else can they be repelled?
The answer, says our entomologist, lies in all-natural, non-toxic patchouli oil.
Here, he explains everything you need to know about this non-toxic pest control method, including why it works and how to increase its efficacy.
How does patchouli oil work to repel ants?
Ryan Smith, pest control technician and owner of Ant & Garden Organic Pest Control explains why patchouli oil works to get rid of ants in your home.
He says, 'Patchouli oil works to repel ants because it overwhelms the scent trails ants leave behind. These trails act like invisible highways that lead other ants straight to food or shelter.
'When you use patchouli oil, the strong, woody scent interrupts that chemical trail and confuses the colony. I’ve tested this on-site with clients who had recurring ant issues, even after removing all food sources.
'In roughly four out of five homes, patchouli oil disrupted the ants’ activity enough to stop new trails from forming for at least 48 hours.'
Patchouli oil, such as the 100 per cent pure Plant Therapy Patchouli Essential Oil available at Walmart, is also one of the most romantic scents for the home, and therefore a far better option for getting rid of ants in the kitchen and elsewhere than chemical alternatives.
Here's how to use it:
1. Spray method
A quick and easy way to use patchouli oil to repel ants is by making a homemade bug spray.
Ryan advises, 'Mix 15 to 20 drops of pure patchouli essential oil [such as the MAJESTIC PURE Patchouli Essential Oil available at Amazon] with one cup of water and 1/2 cup of white vinegar in a 16-ounce spray bottle.' We recommend these Amber Glass Spray Bottles available at Walmart for this.
'Shake it before every use,' he continues. 'Spray it along baseboards, windowsills, under sinks, behind appliances, and wherever you’ve seen ants. Repeat every two to three days.
'In humid environments, daily application might work better until activity stops. I use this mix in homes where chemical sprays aren’t an option due to pets or small children.'
2. Cotton ball placement
You can also use cotton balls, available at Walmart, to repel ants.
'Place five to 10 drops of patchouli oil on cotton balls,' recommends Ryan. 'Tuck them behind trash bins, inside cupboards, near entry points, or any spot where ants enter.
'I’ve found this method useful for keeping ants away from electrical outlets and under-sink plumbing. Replace the cotton every three days, or once the scent fades. You can combine this with cedarwood or clove oil [available at Amazon] for a stronger scent barrier.'
According to Ryan, combining oils increases the effectiveness of this method by around 30 per cent.
'Ants can adapt if exposed to the same scent for too long,' he explains. 'I usually rotate patchouli with oils like peppermint, clove, or cedarwood weekly to keep the colony from adjusting.
'If you combine oils, reduce each one to five to eight drops in the spray to avoid overwhelming your space.

FAQs
What is the best essential oil to repel ants?
While patchouli oil is effective, the best scent for repelling ants is peppermint oil, such as the bestselling Mainstays 100% Pure Peppermint Essential Oil available at Walmart. You can also use peppermint oil to get rid of mice, too.
Meanwhile, clove oil is pungent, and ants hate it. Head of Solved, Punteha van Terheyden found that using plant-powered Dr. Killigan's Six Feet Under insect killer spray from Amazon worked to keep them away for about three days whilst keeping her two cats safe from toxicity.
The natural spray not kill the ant colony, however, so Punteha used Terro ant-killing dust for that, which is a harsher but powerful chemical solution.

'Avoid patchouli “fragrance oils,” as they are synthetic and don’t effectively repel ants,' advises Ryan. Sticking with pure essential oils will give you the most potency and purity.
