Bed bugs are one of the most dreaded pests for homeowners. These small, elusive insects feed on human blood and can cause itching, irritation, and anxiety. What makes them particularly frustrating is how they can infiltrate a home seemingly without notice. Unlike other pests, they are adept at hiding and are often introduced into a home unknowingly. Understanding what attracts them to your home is key to preventing an infestation. In this blog, we will explore the factors that draw these pests in and provide tips on how to minimize the risk of an infestation.
What Are Bed Bugs?
What Are These Pests?
Though these pests prefer hiding in cracks and crevices near sleeping areas, they can be found throughout a home once they infest it. But what exactly draws them into your home? Let’s explore the key factors that attract them.
1. Warmth and Carbon Dioxide
These pests are small, oval-shaped insects that are reddish-brown in color and about the size of an apple seed. They are nocturnal and are most active during the night when they come out to feed on the blood of humans and animals. They do not transmit diseases, but their bites can lead to allergic reactions, skin irritation, and sleep disturbances.
- What you can do: While you can’t change your body’s natural heat and CO2 emissions, understanding this attraction helps explain why bed bugs are often found in bedrooms, hotels, or places with heavy foot traffic. Taking preventive measures to seal cracks around your bed or the room can help.
2. Human and Animal Blood
These insects are parasitic, meaning they feed exclusively on blood. While they prefer human blood, they will also feed on animals like pets if they’re available. They can survive without feeding for several months, but they will actively seek out a blood meal when they need it.
- What you can do: While you cannot completely eliminate the fact that bed bugs are attracted to human blood, it’s important to regularly inspect your living spaces and avoid bringing in infested items such as used furniture or bedding, which may harbor bed bugs looking for their next meal.
3. Used Furniture and Mattresses
One of the most common ways that these pests enter a home is through secondhand furniture, mattresses, or bedding. These items may be infested with them and their eggs, which are often not visible to the naked eye. When people bring these items into their homes, they unknowingly introduce them into their environment.
- What you can do: If you buy secondhand furniture or mattresses, always thoroughly inspect them for signs of bed bugs. Look for dark spots (bed bug excrement), small blood stains, or live insects. If possible, avoid purchasing used furniture, particularly from questionable sources like flea markets or garage sales.
4. High-Traffic Areas
They are adept travelers. They often hitchhike on luggage, clothing, bags, or personal items in public places such as hotels, public transportation, movie theaters, or offices. Once you’ve been in an infested area, these pests may be transported back to your home without you even realizing it.
- What you can do: After traveling or visiting public spaces, inspect your bags, clothes, and other personal belongings for any signs of bed bugs. When traveling, consider using hard-shell luggage, as it’s more difficult for bed bugs to hide in compared to soft bags. Additionally, when returning home, wash and dry clothes on high heat to kill any potential bed bugs that might have hitched a ride.
5. Clutter
These pests are skilled at hiding in dark, secluded places. Clutter around the home provides the perfect hiding spots for them, making it more difficult to detect an infestation early on. The more cluttered a room is, the more places there are for them to hide, making it easier for them to spread unnoticed.
- What you can do: Keep your home, especially your bedroom, free of excessive clutter. By minimizing hiding spots, you can make it easier to spot bed bugs and make it more difficult for them to infest your home. Regularly vacuuming and inspecting your living spaces is essential in maintaining a bed bug-free home.
6. Proximity to Neighbors
They can easily spread from one apartment or home to another, especially in multi-unit buildings like apartment complexes or condominiums. If one unit becomes infested, they can travel through cracks in walls, pipes, and electrical outlets to other units nearby.
- What you can do: If you live in a multi-unit building, be vigilant in inspecting your living space for bed bugs and inform neighbors or your building manager if you suspect an infestation. In cases of confirmed infestations, building-wide inspections and treatments may be necessary to prevent bed bugs from spreading further.
7. Poor Maintenance and Unsealed Cracks
These pests can enter a home through even the smallest of cracks and crevices. Unsealed gaps around windows, doors, and baseboards are common entry points for them. Poorly maintained or older buildings with cracks in the walls or foundation provide easy access for them to enter your home.
- What you can do: Regularly inspect your home for cracks or gaps in walls, floors, and around windows and doors. Seal these openings with caulk or weather stripping to prevent bed bugs from entering your living space. Keeping your home well-maintained can help minimize the risk of infestations.
8. Dirty or Untidy Conditions (But Not Always)
While they are not necessarily attracted to filth, they tend to thrive in places where they can easily hide and find a food source. Homes that are not frequently cleaned or have lots of clutter may provide an ideal environment for them to hide and breed. However, it’s important to note that even the cleanest of homes can fall victim to infestations.
- What you can do: Regularly clean and vacuum your home, paying special attention to cracks, seams of mattresses, and other potential hiding spots. Regular cleaning can help you spot bed bugs early on and prevent them from settling in.
Conclusion
These pests are attracted to several factors, including warmth, carbon dioxide, blood, and the availability of hiding places like cluttered areas and secondhand furniture. While you can’t completely eliminate the fact that they are drawn to certain environmental factors, understanding what attracts them can help you take preventative measures to protect your home. By sealing entry points, inspecting secondhand items, reducing clutter, and practicing vigilance in high-risk areas, you can minimize the risk of an infestation.
If you suspect you have an infestation, early detection and prompt action are crucial in managing the problem before it gets out of control.
