What Attracts Fleas To Kill Them?

Keeping your home and pets safe from fleas can be a constant battle. With their small size and fast reproduction, fleas can hide and multiply quickly, leading to widespread infestations that require a determined effort to eradicate.

This blog post will investigate What Attracts Fleas To Kill Them? We’ll troubleshoot the environmental and biological factors attracting fleas to your home and yard so you can make informed decisions on the best approach for disrupting their lifecycle. Understanding what triggers the presence of these pests is the key to safely eliminating them in your home and keeping them away for good.

What Attracts Fleas?

Fleas are tiny, blood-sucking parasites that live in carpets, cracks, and crevices. To get rid of them, you need to know why they’re attracted to certain places.

They like warm air and vibrations that suggest food nearby. In cold weather, they are attracted to their host’s body heat and the carbon dioxide exhaled by animals or people.

When seeking hosts or hiding places, fleas jump short distances toward darkness and shade from furniture or walls. Vibrations and CO2 signals attract them to beds and carpets where pets sleep and people play, where flea infestations usually start.

What scent are fleas attracted to?

Popular misconceptions suggest that smells and scents entice fleas, yet this is false. The only aroma proven to be attractive to these parasites is their hosts’ (animals and humans). Fleas do not prey on plants as they lack any alluring attractants.

While you may think masking your pet’s natural smell with products and perfumes will work, fleas can still detect the scent beneath several layers. Rather than trying this ultimately fruitless method, it would be more beneficial to eliminate fleas from your home altogether for a longer-lasting solution.

To Stop Fleas From Getting Into Your Home

  • Vacuum regularly, especially around pet beds.
  • Keep pets outside as much as possible.
  • Treat areas where animals gather outdoors, such as wood piles or under shrubs.
  • Use insecticides designed for killing fleas, not general-use pesticides.

How to Identify Flea Infestations

Identifying a flea infestation is the start of eliminating them. Fleas are tiny, dark brown bugs up to 1/6 inch long who feed on people, cats, dogs, and other animals. They like warm and humid surroundings but can survive cold temperatures and hard surfaces.

Flea eggs are tiny (1/50 inch) and range from white to pale yellow. They lie on carpets, furniture, bedding, or other little crevices. Once hatched, larvae (1/4 inch long) hide in carpet fibers and eat skin flakes, food pieces, and flea poop.

Adults lay egg clusters near their hosts, which could be humans if there is no pet in the home. Adults only live for two weeks without a host. They may wander onto your skin when you move through an infested area, such as a park or wooded area, with your pet. They can also jump onto hosts when they sense vibrations from people walking or working in the yard.

You can tell if you have a flea infestation if you notice your pets scratching a lot; black specks on the floor; red marks on arms, legs, or tummy; bumps or lesions from scratching bites; and even itchy welts from saliva after a bite. Once you know, you have an infestation; it’s essential to treat it to protect your family, including fur babies!

Prevention and Control of Fleas

Prevent fleas from entering your home by:

  • Vacuuming rugs and furniture regularly, especially around pet areas.
  • Washing pet bedding with hot (at least 130° F) soapy water weekly to remove larvae and eggs.
  • Mowing the lawn to reduce moist areas where fleas breed.

Over-the-counter treatments like insecticides can help with bites. The boric acid powder is relatively safe and easy to apply for surfaces or items that can’t be treated directly with insecticide. Read the label carefully before using outdoor insecticides to avoid harming yourself or other animals living near you.

Before treating surrounding areas with insecticide, exterminate any possible infestation sites, such as wood piles or burrows, with rodenticides, as some species of flea prey on rodent hosts.

Natural Methods to Kill Fleas

Getting rid of fleas requires breaking their life cycle. 

  • Vacuuming is a great way to start. Dispose of the vacuum bag quickly, or use a bagless machine with a filter that you can clean regularly. 
  • Use clean linens and pet products and vacuum carpets and pet furniture regularly. 
  • Steam cleaning and using heat can help kill larvae. 
  • Natural citrus repellents act as deterrents.
  • Sprinkle diatomaceous earth in unoccupied areas. 
  • Introduce beneficial nematodes into outside yards.

Chemical Methods to Kill Fleas

Killing fleas with chemicals is often the go-to solution for homeowners. There are two main types of chemicals used: insecticides and larvicides.

  • Insecticides kill adult fleas. They can be applied to pets or carpets, depending on the product. Read directions carefully and note that each brand has specific uses for different infestations or parts of the home. Common ingredients in insecticides include pyrethrins, IGRs, carbamates, and organophosphates like malathion and chlorpyrifos.
  • Larvicide treatments stop immature flea larvae from turning into adults. They prevent them from molting due to a chemical reaction in their blood supply. Larvicides come in granule form and must be applied outdoors. Popular larvicides contain cyfluthrin and diflubenzuron (Dimilin).

To avoid fleas in your home, you need a multi-step plan. Vacuuming and using pet supplies designed to fight fleas can help. You may also need chemical pest control treatments in dire cases.

To make it less likely, you’ll get fleas and eliminate items that attract them, like humidity, food sources, and standing water.


Enticing fleas to your trap should be a walk in the park if you adhere strictly to this guide. You’ve now discovered that heat and light can draw fleas, so ensure both are used when setting up traps for the highest efficiency. Utilizing these two elements together is paramount for optimal results!

Remember that fleas are insects, so you can take advantage of their life cycle to get rid of them. Look for tiny white substances – these are the eggs! You can prevent a whole generation before they even hatch by killing them. Invest in products that eliminate all stages of fleas instead of just targeting adult ones.
