Wake up with new itchy bites, often in clusters or lines
Check for small blood spots on sheets, pillowcases, or pajamas
Look for dark fecal spots on mattresses, seams, bed frames, and nearby furniture
Inspect mattress seams, box springs, headboards, and bed frame joints for live bugs
Find shed skins or tiny pale eggs in cracks and crevices
Notice a sweet, musty odor in heavily infested areas
Search for bugs hiding in seams of luggage, clothing, curtains, and baseboards
Use a flashlight to inspect at night, especially around the bed and sleeping area
Compare bite timing with sleeping locations to see if symptoms appear after sleeping in one place
Check pets and their bedding if they sleep near the bed
Contact a pest control professional if you find multiple signs or cannot confirm the source
