We compiled a list of statistics surrounding bed bugs to demonstrate how widespread these pests have become in recent years.
This is because the bed bug epidemic is a fairly recent outbreak.
In the 1950s, bed bugs were all but wiped out in the United States.
But with the rise of international travel, and the world opening up again amidst the COVID-19 pandemic, bed bugs have become more prevalent than ever before.
1. Every year, 1 in every 5 households is affected by bed bugs.
2. Bed bug cases were reported in all 50 states in 2020.
3. Bed bugs are 60% more likely to bite the upper torso rather than areas on the lower body.
4. It takes 7 weeks on average for a modern bed bug infestation to be discovered.
5. Bed bugs are more common in homes and apartments, with the 3rd-highest percentage of infestations occurring in hotels.
6. Between 55 and 75 degrees F is the optimal temperature for bed bugs to spread.
7. Bed bugs are commonly confused with other household pests. 71% of reported infestations are initially believed to be a flea problem. Another 24% are attributed to cockroaches. (5% other pests)
8. Close to 97% of bed bug professionals perform bed bug treatments on an annual basis. 66% of them agree that as bed bug populations continue to grow, more and more cases will be reported.
9. Around 50% of all bed bug treatments are performed in the summer. This is the period when bed bugs are at their most active, as well as when many travel for vacation.
What Percentage of Homes Have Bed Bugs?
Studies have shown that 1 in every 5 households report bed bug infestations every year.
While bed bugs can live in the wild, their survival hinges on infiltrating a house, apartment or other building and establishing a colony. They prefer to make their nests in remote places, like the insides of furniture or in cracks in the walls.
Bed bugs aren’t picky about the state of a home. While they can thrive in less-than-sanitary environments, houses and apartments that are relatively clean also suit their needs.
This is why highly-rated hotels occasionally have reports of bed bug infestations as well.
As long as bed bugs have regular access to food and hiding places, they’re able to adapt to their surroundings in no time at all.
How Common are Bed Bugs in the US?
Bed bugs can be found in all 50 states. They are more commonly found in warmer regions of the US, where the temperatures are more consistent.
Below is a detailed table from a global pest management association that shows the percentage of bed bug infestations by region of the United States.
|U.S. Region||% of Infestations|
Some states have a higher rate of infestations than others. Based on Orkin’s 2021 Bed Bug Cities list, the following states have the worst bed bug problems:
- Ohio (6 cities on Orkin’s list)
- Michigan (4 cities)
- Florida (3 cities)
- Illinois (3 cities)
- New York (2 cities)

How Many Times Can 1 Bed Bug Bite at Once?
Bed bugs will bite multiple times over the course of a single night, as they are constantly hungry for human blood. You could have several bites grouped together and they could all have been made by a single insect.
Bed bugs are nocturnal feeders. They feed when people are fast asleep, and typically bite along the upper torso. Common areas for bed bug bites include the head, neck, shoulders, and arms.
(These are the areas with the most exposed skin.)
Bed bugs are 60% more likely to bite along the upper body than the lower body. Since the lower extremities are often covered by more clothing, it’s harder for bed bugs to locate spots to feed on.
When bed bugs bite, they inject anticoagulants and antihistamines into the bloodstream.
These compounds prevent the blood from clotting while they drink, and also prevent immediate itching.
Symptoms of bed bug bites include red-colored welts and itchiness around the area of the bite.
More severe symptoms can include:
- Flu-like symptoms
Psychological symptoms are also possible. These can include insomnia, increased anxiety and post-traumatic stress.
How Long Does It Take For a Bed Bug Infestation to Start?
How quickly a bed bug infestation spreads is dependent on several factors. These include temperature, location, how often the bed bugs feed, and how often they are breeding.
Generally, it takes 7 weeks for a bed bug to complete its development cycle from larva to adult.
So… if you’re dealing with any kind of infestation, then it has been ongoing for at least that long.
There are 2 types of infestations:
- Severe infestation
- Light infestation.
In cases of severe infestation, it can be hard to pinpoint when the infestation first started. The bed bugs will have developed into a thriving colony by this point, meaning they have managed to elude detection for at least several months.
In a lighter infestation, it becomes easier to figure out. A light bed bug infestation means that, while bed bugs are still a problem, they have yet to fully develop as a group. The infestation is still in its early stages, making exterminating these pests more manageable if you can isolate them.
How Common Are Bed Bugs in Hotels vs. Homes?
Bed bugs can be found wherever people tend to gather, though they are especially common in travel hubs like airports, bus stations, and hotels.
On average, 68%of bed bug infestations are reported in hotels. These cases aren’t exclusive to lower-end motels, either: even 5-star hotels occasionally fall victim to infestations.
At home, bed bugs are even more common. Many people will report a bed bug problem in their residence after returning from a trip, meaning the bed bugs stowed away in their luggage.
46% of bed bug infestations happen in single-family homes.
While 28% occur in apartment complexes.
Hotel Bed Bug Reports
Below are some examples of famous bed bug cases:
- In June 2018, Brazilian model Sabrina Jales St. Pierre sued Hilton Hotels after she was bitten by bed bugs in her room. St. Pierre received over 90 bites on her body, which left her traumatized in the immediate aftermath of her stay.
2. The Lake Louise Chateau in Calgary, Canada was forced to pay $24,000 in damages following a settlement in March 2021. Omar Abdulhak, an Edmonton lawyer, was bitten by bed bugs during his 2-day stay at the hotel. The Chateau had a history of reported bed bug incidents; suspiciously, their own internal investigations never confirmed the presence of bed bugs in their rooms.
Bed Bug Temperature Charts
Bed bugs prefer living in warm climates, which explains why they are so common in the Southern United States. They prefer temperatures between 55 and 75 degrees Fahrenheit.
Even in colder regions…
Bed bugs can find ways to survive.
Since they primarily live indoors, cold temperatures are rarely a threat to them.
If bed bugs are introduced to frequent cold, they will enter a period of hibernation called diapause. During diapause, a bed bug’s development cycle completely stops, resuming when the temperature gets warmer.
Extreme temperatures are capable of killing bed bugs, though as with most extermination methods, it takes time to be truly effective.
Bed bugs will die if exposed to extreme cold.
(Any temperature below 0 degrees Fahrenheit for a period of several days).
Heat treatments are commonly used by exterminators to kill large infestations. Specialized heaters are used to raise the temperature above 125 degrees Fahrenheit, enough to kill adults and eggs.
Steam cleaning is even more effective, with temperatures capable of reaching 160 degrees Fahrenheit.
How Often are Bed Bugs Confused for Other Pests?
Bed bugs are commonly confused with other household pests, due to their small size and the similarities between bug bites. Pest professionals report that in 84% of bed bug cases, they are called to deal with another pest.
The vast majority of bed bug infestations are initially attributed to fleas. 71% of reported infestations are initially believed to be a flea problem.
Another 28% of infestations are reported as cockroaches.
There are ways to determine whether or not you are dealing with bed bugs:
- Pay attention to the area around your bed. Bed bugs commonly leave signs of their presence in bedding material or around the bed frame, such as fecal matter and discarded skins.
- Blood stains on your bed are another sign of bed bug activity. Since bed bugs can’t walk very fast, they may be crushed when a human moves in their sleep. The blood stains are all that remains of any bed bug that got squashed in the night.
- If you notice bite marks, pay attention to where they are. Bed bug bites are usually found along the upper torso, including the face, neck and arms. They also appear in small, zigzag-like patterns.
Do Pest Professionals Treat Bed Bugs Often?
Pest control experts help treat a staggering number of bed bug cases annually. As of 2018, 97% of all pest professionals were called to deal with at least 1 bed bug infestation during the year.
And the pest industry is confident that the number of cases will only continue to grow.
66% of pest experts agree that bed bug populations are still on the rise, which will lead to a steady influx of new cases in the years to come.
Bed bugs are also considered to be the most difficult pests to eradicate. 62% of exterminators share this sentiment, compared to 12% who think cockroaches (which are notoriously difficult to kill) are the hardest pests to get rid of.
What Season Are Bed Bugs Most Active In?
As described earlier, bed bugs are at their best in warmer climates. This means that, like all other pests, they are most common during the summer.
50% of bed bug treatments are performed over the course of the summer.
Summer vacations are another factor contributing to the surge in bed bug cases during this season. Millions of people are out of school or take time off of work to travel, and they may inadvertently bring bed bugs home with them.
