Which combination is listed as part of bedbug control techniques?

• A. Chemical fogging only
• B. Apply steam + Vacuum
• C. Regular watering of plants
• D. Diatomaceous earth exclusively

Answer: (B)

Bedbug control relies on an integrated approach that combines effective means to reach hidden pests with methods that physically remove them. Using steam delivers intense heat to cracks, seams, and other tight spaces where bedbugs hide, killing nymphs and eggs on contact when applied correctly. Vacuuming complements this by physically removing live bugs, eggs, and debris from surfaces and crevices, reducing the population and removing hiding places. Together, steam and vacuum address both exposed bugs and those tucked away in furniture and seams, making this combination a practical part of control efforts. Other options aren’t as reliable on their own: chemical fogging alone often misses hiding spots and can pose safety concerns; watering plants has no effect on bedbugs; diatomaceous earth can be supportive but isn’t typically sufficient by itself and depends on proper application and contact time.
