Surprising Facts About Wild Animals During Winter

Critter-Repellent.com Staff • Dec 03, 2020

The changing seasons mean changing animal behavior

The holiday season is upon us! Little do many people know, but humans aren't the only ones who gain a little weight throughout the winter months. While not every animal hibernates through the winter, many animals develop new behavior patterns as the weather turns colder. From dietary changes to novel survival strategies, wildlife’s winter time reponses can easily go unnoticed. Here are some surprising facts about wild animals throughout the winter:

Annual fur changes – While some animals rely on fat stores in order to survive frigid winter temperatures, others completely regrow their fur. Most notably, deer will grow thicker, darker guard hairs, as well as a more robust undercoat. This thicker fur will be darker in color than the spring and summer coats which deer sport; unlike the snowshoe hare. This medium-sized species of hare is a coarse brown/grey during the warmer seasons, but grows a thicker, longer coat for winter which is nearly stark white, allowing the animal to better blend in with the snowy surroundings. 

Bears are not true hibernators – While probably pop culture’s favorite hibernating animal, bears do not meet the threshold of bodily-function-reduction requirements for true hibernation. The animal’s heart rate and oxygen consumption will drastically decrease, but bears are relatively easy to awaken during their winter rest. Despite not being true hibernators, bears will not defecate or urinate during the winter months, instead their bodies will recycle the nutrients in these potential bodily wastes. 

Hibernation is not spent completely asleep – Animals that do hibernate will not spend the entire winter in a deep sleep. While the metabolism of hibernators takes a drastic decline, the animals still need to awaken every so often in order to eat, hydrate, and pass waste. If you happen upon an animal which is supposed to be hibernating during the winter, chances are good they are perfectly healthy and just in need of a snack!

Food is still bountiful – Many people assume that a lack of vegetation means that there is a lack of food available for wild animals. It is however the case that many herbivorous animals will switch their diets from greenery and flowers to bark, small sticks or twigs, and sometimes mosses which remain on rocks. These more fibrous foods can be harder to digest for the animals in search of a good dinner, but provide starchy nutrients in order to keep the animals well insulated through the coldest months of the year.


Birds can migrate using the Earth’s magnetic field – Birds can’t use a GPS, so they had to figure out their own path for their annual trips south. Some birds seem to more heavily rely on sensory input within the bounds of human comprehension. Visual cues and mental maps of terrain both play a role in a bird’s migration path, but magnetoreception is a major player in their movements. Salmon and butterflies are both capable of this same skill of reading the Earth’s magnetic field in order to migrate.


Winter brings change to not just the environment, but to everyone and everything which lives in an area affected by winter weather. No matter if the animal in question is a hibernator or not, the wildlife around you is sure to be behaving differently as the cold weather tightens its grip across the northern hemisphere.

Living alongside pests is not something we humans take kindly; there’s something peculiarly unsettling about sharing our home with other creatures that are neither pets nor guests. The discomfort of dealing with infestations often drives us toward quick-fix solutions, mostly in the form of powerful chemicals. However, a deeper understanding of the risk factors associated with toxic pest control chemicals might stir us to reconsider this approach. There are plenty of natural alternatives that not only do the job effectively but also can evade any potential harm to you or your loved ones. What Do Pest Control Chemicals Actually Contain? Most pesticides often contain hard to pronounce ingredients that can leave even harder impacts on our health and environment. Chemicals like permethrin, bifenthrin, or imidacloprid may not ring a bell. But let’s simplify it and say that these potent substances are designed to incapacitate and kill pests effectively. The issue? Pests don’t live exclusively in your garden or the dark corners of your attic or basement. They come into our personal space –– on our kitchen counters, under our beds, inside our drawers…the list is endless. This means that pest control chemicals often end up where we live and breathe. So, what does this actually mean for us? Health Risks Linked with Toxic Pest Control Chemicals The reason behind toxicity warnings on many pest control products isn’t lore or legend; there’s actually some substance to it all. According to a study done by Cogent Medicine , prolonged exposure to potent substances like organophosphates may result in health complications ranging from mild skin irritations all the way up to serious neurological and reproductive issues. Children are particularly susceptible, as these chemicals can interfere with the nervous system’s development. Symptoms like dizziness, nausea, headaches, or even seizures can occur if these toxic pesticides get into your bloodstream. In serious cases, exposure can lead to longer-term health problems like cancers and endocrine system disruptions. And then there’s also the potential damage they might do to your beloved pets. They may experience vomiting, tremors, or even worse if they’re exposed to these chemicals. Ecological Impact of Toxic Pest Control Chemicals Pest control measures not only wreak havoc on human and pet health but also significantly impact our environment. The chemicals used in many pesticides can contaminate the soil, water, and air around your home. To make matters even worse, these substances are not quick to break down. They tend to accumulate over time gradually creating a toxic environment for other creatures who share our ecosystem. From insects essential for pollination to birds and aquatic animals, all of these are in danger. Natural Pest Control Alternatives With all these health risks, it doesn’t mean we must resign ourselves to living alongside pests. Natural pest control alternatives are not just safe but often equally effective against unwanted pests in your home. Here are a few natural solutions you may want to consider: Beneficial insects : You can introduce natural predators into the environment to combat pests in your garden or outdoor spaces. Parasitic wasps for aphids or ladybugs for mites and whiteflies are some good examples of this strategy. Diatomaceous earth : Composed of fossilized algae, this fine powder is as lethal as it is organic against a wide array of insects. If you’re dealing with bed bugs, roaches, or ants, the sharp microscopic particles cut through their exoskeletons like glass shards do to our skin. Essential oils : It’s not just about a pleasant fragrance; many essential oils also serve as efficient deterrents to pests. Peppermint, eucalyptus, lavender, and tea tree oils have all shown promising results against a variety of pests and also act as natural fly repellents that actually work. Physical barriers : For certain types of pests, such as slugs and snails, a simple but strategically placed barrier could work wonders. A copper tape around plant pots will irritate these creatures’ slimy undersides enough to make them turn back. Homemade traps : Crafting homemade traps is a simple yet efficient method that can be surprisingly effective for managing pests. For example, try using some ripe fruit in a jar to trap flies or adhesive traps lined with food particles to catch cockroaches. Homemade solutions : A little online research opens up a world of homemade sprays and solutions that can deter pests. For example, a simple soap and water solution can be sprayed directly on flies, aphids, or other insects to dehydrate them. You can also create a mixture of hot pepper or vinegar to repel insects. Planting specific plants : Some plants naturally give off scents or produce chemicals that deter pests. Incorporating these plants into your home garden, landscaping, and outdoor living areas can be an effective natural pest control measure. Basil, lemongrass, mint, lavender, and marigold are just some examples. Going Green Against Pests As Theodore Roosevelt said: "Do what you can, with what you have, where you are." So, the next time you have a pest problem, give these natural alternatives a shot. Not only are they healthier and more sustainable, but you’ll also have the satisfaction of watching pests scurry away from the wholesome power of nature.
