How Long Does It Take to Kill Bed Bugs?
It usually takes around three weeks to get rid of bed bugs using a professional pest control service. Pesticides used to kill bed bugs do not kill bed bug eggs, necessitating the application of more pesticide two to three weeks later.
Some home products such as contact insecticides kill bed bugs shortly upon contact. Insect growth regulators kill more slowly by altering the development and reproduction of the bugs. Insecticidal dusts cause the bugs' coat to dry out, resulting in quick death. As with professional treatment, an additional treatment is necessary after the initial treatment, since these pesticides don't affect the eggs.
On linens and other items, bed bug eggs die after approximately 60 minutes of high heat in a dryer or when frozen for 30 days.
