Deciding what month you want to go on your Grand Canyon rafting trip is a big decision. Let’s talk about rafting in September!

One of the most common packing questions we get is:
“Do I need to bring bug spray for my river trip?”
Our answer is usually no—and here’s why.
Yes, there are bugs in the Grand Canyon—but not the kind that typically bug you (pun intended). Here’s a breakdown of what you might encounter:
But the bug that most people worry about—mosquitoes—is virtually nonexistent in the Grand Canyon.
It might seem hard to believe. After all, there’s water down there, right?
Yes, but the key difference is that mosquitoes need standing or slow-moving water to breed. The Colorado River is fast-moving, and its water levels fluctuate constantly—conditions that make it nearly impossible for mosquitoes to survive, let alone breed. The same goes for the canyon’s sidestreams. While there are occasional pools, they’re temporary and usually dry up or refill depending on sun and rain.
While mosquitoes aren’t an issue, you may occasionally spot a horsefly—but it’s uncommon. There are also a few bees that can sting, though they tend to keep to themselves.
You’re welcome to bring it if it gives you peace of mind, but it’s definitely not a necessity.
If you do choose to bring bug spray, please make sure it’s DEET-free. DEET can be harmful to the delicate ecosystem of the canyon.
