❓ Frequently Asked Questions

Will bleach kill bed bug eggs?
Bleach in direct contact with eggs can kill them, but bed bug eggs are laid in cracks and seams you can't reach with bleach without damaging your furniture and bedding. Bleach is not a useful bed bug treatment.
Does alcohol kill bed bugs instantly?
91% isopropyl alcohol kills bed bugs on direct contact. However, it evaporates within minutes leaving no residual, it's a fire hazard, and it can't reach bugs hiding in cracks. It should not be used as a primary treatment.
