Based on the provided information, high temperature, specifically heat, is what reliably kills bed bugs and their eggs when exposed to the required conditions.
Understanding How Heat Kills Bed Bugs
Heat treatment is a highly effective method for eradicating bed bugs. By raising the temperature of an environment (like a room or specific items) to a certain level for a sufficient duration, it disrupts the biological functions of bed bugs and their eggs, leading to their death. This process, once the necessary temperature is reached and maintained, automatically results in mortality without the need for further intervention.
Specific Temperature Requirements for Bed Bug Mortality
The time it takes for bed bugs and their eggs to die from heat exposure depends directly on the temperature achieved. Higher temperatures kill them more quickly.
According to the reference:
- Bed bugs exposed to 113°F will die if they receive constant exposure for 90 minutes or more.
- They will die within 20 minutes if exposed to 118°F.
- Bed bug eggs must be exposed to 118°F for 90 minutes to reach 100% mortality.
Here's a summary in a table format:
| Target | Temperature (°F) | Exposure Time Required | Outcome |
|---|---|---|---|
| Adult/Nymph Bed Bugs | 113 | 90+ minutes | Mortality |
| Adult/Nymph Bed Bugs | 118 | Within 20 minutes | Mortality |
| Bed Bug Eggs | 118 | 90 minutes | 100% Egg Mortality |
Why Heat Treatment is Effective
Reaching and maintaining these specific temperature thresholds ensures that bed bugs and their eggs cannot survive. Once the environment or infested items reach these critical temperatures for the required duration, the process of killing the pests occurs reliably and "automatically" as a result of the heat exposure. This makes heat treatment a powerful tool in eliminating infestations when performed correctly.
