Spending time in the backcountry is one of the most rewarding pursuits a man can undertake, but it comes with a responsibility to understand the environment you're entering — and the animals that call it home. Most campers know the basics: don't leave food out, hang your bear bag, clean up after meals. What fewer people realize is that predator attraction goes well beyond the obvious, and some of the most common campsite habits are silent invitations to wildlife you'd rather not encounter up close. Bears, mountain lions, coyotes, and other opportunistic predators have finely tuned senses that pick up on cues the average camper would never consider a threat. Understanding animal behavior and sensory triggers isn't just about safety — it's about traveling through wild places with the awareness and respect the wilderness demands.
Citronella candles are a go-to for campers trying to dodge mosquito bites without heavy chemicals, but Colorado Parks and Wildlife explicitly warns against burning them in camp because their strong citrusy scent can attract bears. The sweet, fruit-like smell of citronella mimics the odor of ripe fruit, which bears are naturally drawn to — and a bear's nose is powerful enough to detect even an unlit candle left sitting in your campsite. The problem is doubly frustrating because a 2017 study published in the Journal of Insect Science found that citronella did essentially nothing to repel mosquitoes in the first place. The same risk applies to citronella-based sprays and lotions applied to skin or clothing, which carry the scent directly into your sleeping area. If bug protection is the goal, DEET or picaridin-based repellents are far safer choices in bear country.
One of the most overlooked predator attractants at camp is the shirt and pants you wore while grilling dinner. Fabric absorbs food odors deeply, and Colorado Parks and Wildlife and the U.S. Forest Service both specifically warn against sleeping in clothes you cooked in, advising campers to store those garments with their food supply overnight. Bears don't distinguish between the smell of a bacon skillet and the hoodie it perfumed — both register as a potential food source to an animal with a sense of smell up to 2,100 times more sensitive than a human's. Bear management specialists have documented incidents where bears tore through tents to reach clothing that smelled of cooking residue. Change into a clean set of clothes before entering your tent, and seal your cooking layers in an odor-proof bag stored well away from your sleeping area.
Most campers know to lock away food, but the scented toiletries sitting in your tent are equally dangerous in bear country. Toothpaste, sunscreen, lip balm, deodorant, lotion, and even menthol cough drops all carry strong non-food scents that bears investigate with the same intensity they'd direct at a food cache. Bear management specialists report numerous incidents where bears tore through tent walls to reach toothpaste or deodorant — bears simply don't differentiate between food smells and other intriguing chemical odors. The REI Expert Advice guide for backcountry camping specifically lists personal hygiene products like toothpaste, sunscreen, and feminine products as items that must be stored in a bear canister, not left in your tent. A simple rule of thumb: anything that touches your skin or goes in your mouth belongs outside your sleeping area.
Many campers believe tossing food scraps and wrappers into the campfire is a tidy, bear-safe way to dispose of waste, but it's actually counterproductive. A campfire isn't hot enough to fully incinerate food waste, and the burning process releases intensified food odors into the air across a far wider radius than a sealed trash bag ever would. Colorado Parks and Wildlife explicitly states never to burn garbage or leftovers for exactly this reason, noting that land managers observe bears making a beeline for old fire pits where partially burned food remains. What's left behind in the ash — charred grease, sugars, and protein residue — is just as detectable to a predator's nose as fresh food. All waste, including food packaging, should be packed out in sealed odor-proof bags rather than thrown in the fire.
Pitching your tent next to a picturesque creek or along a forested trail might seem like ideal camping, but those are precisely the corridors predators travel most frequently. Colorado Parks and Wildlife advises setting up camp well away from stream banks, lake shores, and obvious wildlife trails because these are the routes bears, mountain lions, and coyotes use as daily travel corridors. Camping beside running water compounds the problem because the ambient noise of the stream makes it difficult for both you and wildlife to hear each other approaching, dramatically increasing the likelihood of a surprise close encounter. Mountain lions in particular are tactical hunters that monitor game trails constantly and use dense, terrain-adjacent cover to stage ambushes. Choosing open ground at least 200 feet from any established trail or water source significantly reduces the chance of your tent landing in the middle of an active hunting route.
It's an uncomfortable reality most camping guides bury in fine print: bears and mountain lions are actively attracted to the scent of human urine and excrement. These predators use bodily waste as territorial and biological information, and a fresh scent near your campsite signals recent mammal activity worth investigating. Wildlife safety sources consistently recommend walking at least 100 yards from camp before relieving yourself — a distance most campers drastically underestimate when stumbling out of a tent at 2 a.m. The problem is amplified at night, which is precisely when large predators are most active and most likely to be moving through your area. Designating a specific, well-marked latrine spot far from your sleeping area — and using it consistently throughout your stay — is a simple but genuinely important defensive habit in bear and mountain lion country.
