When exposed to extreme heat, their metabolic processes fail, leading to their demise. For a detailed explanation and demonstration of how heat treatment works, check out this YouTube video:

Does keeping your house hot kill bed bugs?

Keeping your house hot at typical indoor temperatures is not sufficient to kill bed bugs. While bed bugs are uncomfortable at higher temperatures, they can survive in temperatures up to 113°F (45°C) for extended periods. To kill bed bugs effectively, the temperature needs to reach at least 120°F (49°C) and be maintained consistently for several hours. This level of heat cannot be achieved by merely turning up your thermostat. Professional heat treatments or specialized equipment are necessary to eradicate bed bugs effectively using heat.

Why do bed bugs die in heat?

Dead bed bugs

Heat is a highly effective method for killing bed bugs because it disrupts their biological systems in multiple ways. Below are the key effects of heat on bed bugs and how these mechanisms lead to their death:

  • Protein Denaturation: Heat causes essential proteins in the bed bugs’ bodies to lose their structure, disabling vital biological functions.
  • Cell Membrane Damage: High temperatures rupture cell membranes, leading to the loss of cellular integrity and function.
  • Dehydration: Extreme heat accelerates water loss in bed bugs, resulting in fatal dehydration.
  • Metabolic System Failure: Heat overwhelms their ectothermic regulation, disrupting energy production and repair mechanisms.

These combined effects make heat an effective solution for eradicating bed bugs at all life stages.

The Science of Heat Treatment: Understanding How Heat Kills Bed Bugs

Why are bed bugs vulnerable to high temperatures?

Bed bugs are vulnerable to high temperatures because, as ectotherms, they’re unable to regulate their own body temperature. Their survival depends on the surrounding temperatures. Therefore, an environment that’s too hot will disrupt their physiological processes.

How do bed bugs regulate their body temperature?

Unlike mammals that regulate their internal body temperature, bed bugs rely on the environmental temperature to maintain their body temperature—simply put, if it’s warm, they are warm; if it’s cool, they are cool.

At what temperature do bed bugs die?

The effectiveness of heat in killing bed bugs depends on the temperature and exposure time. The table below summarizes the specific temperature thresholds required to kill adult bed bugs, nymphs, and eggs, along with the corresponding timeframes for maximum efficacy:

Temperature (°F/°C)Exposure TimeEffect on Bed Bugs
113°F (45°C)Several hoursSlows activity but may not kill all life stages.
115°F (46°C)90 minutes or moreKills adults and nymphs effectively.
120°F (49°C)Several hoursRequired to kill eggs; ensures full eradication.
122°F (50°C) or higherFew minutesInstant kill for all life stages due to extreme heat.

What temperature kills bed bugs instantly?

Instant death for these bugs can be achieved at a more extreme temperature. Exposing bed bugs to heat levels of 122°F (50°C) can kill them in a matter of minutes.

What temperature kills bed bugs and their eggs?

While adults and nymph-stage bed bugs succumb at temperatures upward of 115°F (46°C), eggs are a bit more hardy. To ensure the heat treatment targets the eggs as well, the temperature should be increased to around 120°F (49°C).

Will 100 degrees kill bed bugs?

A consistent temperature of 100 degrees Fahrenheit may not be enough to kill all bed bugs, especially the eggs. More intense heat is usually required for a comprehensive elimination of these pests.

To what temperature do professional bed bug exterminators heat homes to kill bedbugs?

Professional bed bug exterminators heat homes to a consistent temperature of 120°F to 135°F (49°C to 57°C) to effectively kill all life stages of bed bugs, including eggs. This temperature is maintained for several hours to ensure the heat penetrates deep into walls, furniture, and other hiding spots. This method, known as whole-home heat treatment, is one of the most reliable ways to eradicate bed bugs without using chemicals.

How long should the heat exposure last to ensure bed bug death?

Although a core temperature of 115°F (46°C) can kill adult bed bugs, it only works if sustained for around 90 minutes. Lower temperatures may require longer exposure times to reach the same effect. Short-term exposure to these temperatures will not ensure the comprehensive extermination of the bed bugs.
