Head lice cannot live long on couches; they die within 1-2 days (or 24-48 hours) without a human host to feed on, so the risk of getting lice from furniture is very low, but cleaning items that had direct head contact (like pillows, throws) by washing or vacuuming is recommended to remove any stragglers and prevent potential transfer. Lice prefer the scalp and need blood to survive, making furniture an unsuitable habitat, but you should still clean items used in the 48 hours before treatment.

Can a hair dryer kill lice?

No, you should not use a regular hair dryer to kill lice due to high burn risk and inefficiency; specialized hot-air devices (like LouseBuster) work by dehydrating lice, but a standard blow dryer lacks the controlled, consistent airflow needed and can spread lice, making it unsafe and ineffective for killing both lice and their eggs (nits). Professional heat treatments use controlled, high-volume airflow, not just heat, which is different from home blow dryers.
 

Will a shower cap suffocate lice?

Lice need air, so smothering them can work, but commercial treatments with permethrin or pyrethrin are more reliable; a shower cap is primarily for keeping messy treatments contained.
