Fumigation involves sealing your home and filling it with a gas, such as sulfuryl fluoride, that penetrates every crack & crevice where bed bugs may be hiding. This process typically lasts 24 to 72 hours.

The gas suffocates & kills…

• Adult bed bugs

• Nymphs (young bed bugs)

• Eggs

Once fumigation is complete & the gas has cleared, no live bed bugs should remain.

Do Bed Bugs Ever Survive Fumigation?

If the fumigation was done properly by a licensed professional, survival is extremely unlikely. But few reasons bed bugs might survive include…

• Incomplete treatment due to poor sealing or missed areas

• Reinfestation from items brought back in too soon

• DIY fumigation products that aren’t strong enough

Signs Bed Bugs Are Truly Gone

After fumigation, monitor for signs such as…

• No new bites

• No live bugs or droppings

• No blood stains on sheets

• No musty, sweet odor

A professional pest control company may recommend a follow-up inspection just to confirm the treatment was 100% effective.

Bed bugs typically die within hours of proper fumigation. The treatment kills them in all life stages, making it one of the most reliable solutions for serious infestations. As long as the process is carried out by trained professionals and you follow post-treatment instructions, the chance of any surviving bed bugs is very low.
