Tick Prevention - Ant Pheromones

Researchers at Simon Fraser University in Vancouver, British Columbia, have discovered that certain species of ticks, including those that spread Lyme Disease, are repelled by pheromones emitted by ants. These findings have prompted efforts to synthesize these ant excretions and develop them into tick repellents. Unlike traditional tick sprays like DEET or Citronella, the scent derived from ant pheromones is virtually imperceptible to humans.

The study, published in Royal Society Open Science, focused on how ticks avoid predation by common enemies like ants, spiders, and beetles. Researchers found that ticks retreat upon detecting chemicals left behind by these predators. Further investigation honed in on pheromones produced by ants due to their extensive use of chemical communication within social colonies.

After identifying the specific pheromones that deter ticks, researchers collaborated with chemists to produce synthetic versions. These synthetic ant scents proved effective in repelling ticks, potentially offering a novel approach to tick control. The team envisions incorporating these pheromones into spray-on repellents or environmental barriers to combat tick-borne diseases.

While there's no set timeline for the release of tick sprays containing synthetic ant pheromones, the researchers have filed a provisional patent and are working with industrial partners to bring the product to market. They are also exploring the possibility of combining ant pheromones with other repellent compounds for enhanced effectiveness. Interestingly, some bird species engage in "anting," a behavior where they use dead ants to deter parasites, suggesting that the concept of utilizing ant pheromones for pest control extends beyond human applications.
