Can Bed Bugs Live Outside in the Summer?

Warm summer months bring more than sunshine—they can also impact pest activity, including bed bugs.

Understanding their behavior in warmer weather is key to preventing infestations and protecting your home.

Can Bed Bugs Survive Outside in the Summer?

Limited Outdoor Survival

Bed bugs are indoor pests by nature, relying on human environments to thrive. While they can survive outdoors temporarily, they are not well-adapted to outdoor conditions for extended periods.

Environmental Factors That Affect Survival

Outdoor survival depends on:

• Temperature: Prolonged exposure to extreme heat or cold can kill bed bugs.
• Humidity: Dry conditions can lead to dehydration.
• Sunlight: Bed bugs prefer dark, hidden areas—exposure to direct sunlight can be harmful.

Without consistent access to food and shelter, their chances of long-term survival outside are low—even in the summer.

What Do Bed Bugs Dislike?

To help repel bed bugs, it helps to know what they hate:

• Heat: Temperatures above 113°F (45°C) can kill bed bugs after prolonged exposure.
• Sunlight: They avoid bright, sunny environments.
• Certain Scents: Natural oils like lavender, peppermint, and tea tree oil are known to deter bed bugs.

Use this knowledge to create environments that are less inviting for pests.
