How long does it typically take for a bed bug to finish a meal?

Bed bugs are known to have a specific feeding behavior that allows them to complete their meals efficiently. Typically, it takes about 3 to 10 minutes for a bed bug to finish feeding. This quick feeding time is primarily due to their feeding method, where they inject saliva containing anticoagulants to keep the blood flowing while they feed.

Choosing this time frame reflects the biological adaptations of bed bugs, which need to feed quickly and then return to their hiding places to avoid detection. In terms of survival and reproduction, the ability to feed efficiently helps them thrive despite being in environments with human occupants who might try to eradicate them.

The other time frames provided don't accurately reflect the bed bug's feeding habits, as they would suggest a feeding duration that is either too short or significantly longer than what is observed in their natural behavior. For instance, both the shorter and longer options are outside the typical feeding range for these pests, leading to an understanding that the correct response aligns with established knowledge about their feeding behavior.
