Cayenne’s intense aroma and irritating compounds overwhelm ants’ senses and disrupt their trail-following instincts. It doesn't kill ants, but it does keep them away from treated areas.
Identify common ant entry points—like along baseboards, around doorways, or near cracks and crevices.
Sprinkle a fine line of cayenne pepper along these areas to create a scent-based barrier.
Reapply as needed, especially after vacuuming, mopping, or if the powder gets disturbed.
Notes
Safety: Cayenne pepper can cause irritation if touched or inhaled. Keep this one far from pets and curious kiddos, and avoid applying it in high-traffic areas where it might get kicked up or spread.
