Their sense of smell is remarkable. Yet there are only a few scents they find alluring. There are some scents that repel them as well. But which are which? Discover three smells that attract fleas (and a few that repel them!).
Discover 3 Smells that Attract Fleas
1. Carbon Dioxide
Interestingly, the scent of carbon dioxide (which is odorless to you) is a scent that attracts fleas. That means that your natural exhale can catch a flea’s attention and draw it closer to you.
Fleas flock to garbage cans and though they can pick up the scent, it’s not the only reason they gravitate toward trash. Fleas are also attracted to heat and a steaming pile of garbage is appealing to them.
Pets emit their own scents, including when they exhale. Just like humans, pets expel carbon dioxide when they exhale, which is a smell that fleas are attracted to.
Smells That Repel Fleas
You can probably guess what citronella smells like. It’s citrusy, much like a lemon, and is quite pleasant to humans. However, fleas do not like it. It’s great to use as a repellant since there are other insects that abhor it as well, including mosquitoes.
Eucalyptus also incorporates traces of citrus, but it has a sharper smell that includes mint and honey. Some might describe the scent as medicinal. Mixing this essential oil with warm water provides you with a spray you can use to repel fleas.
The smell of mint makes up part of the scent of eucalyptus but alone, it’s not just minty. It may also have hints of chocolate, wintergreen, and even apples and lemons. This is a strong, refreshing scent for you but for fleas, it’s unpleasant.
How to Keep Fleas Away
Keeping fleas away requires you to keep your environment clean. That means regular sweeping and vacuuming, including any sofas and cushions. When you empty your vacuum bag or container, do so outdoors. Ensure you keep your (and your pet’s) bedding clean, washing frequently with both soap and water.
You can use essential oils as natural repellants in rooms your pets don’t enter as they can be toxic to your four-legged friends. Ultimately, fleas are attracted to carbon dioxide and warmth and you’re emitting both all day. Prevention of an infestation along with a tick and flea treatment for your pets can keep these tiny, persistent critters away.
