It’s National Black Fly Day! 🪰

If you live in the foothills, you know about black flies! These small, persistent flies are known for biting around the face and can be a serious nuisance.

Our vector control team monitors and manages black fly populations to help keep these biting pests in check.

POV: You thought your biggest problem on this journey was making it home… 🌊⚔️
Meanwhile, the mosquitoes: “bet.” 🦟😭

Don’t start your own Odyssey without repellent.
🧴 Wear it.
🛡️ Protect yourself.
🦟 Tell the mosquitoes to find another hero.

Because getting bitten 47 times was NOT part of the plot. 💀
