So you've scheduled a termite fumigation. The hard part — deciding to move forward — is done. Now comes the preparation, which is where a lot of homeowners feel uncertain. What exactly do you need to do before the tent goes up? What can stay, what needs to go, and how do you make sure everything goes smoothly?
This is the complete, practical checklist you need — organized so you can work through it efficiently in the days before your fumigation date.
Why Preparation Matters
Fumigation preparation isn't just administrative — it directly affects both the effectiveness of the treatment and the safety of your household. The fumigant needs to reach every part of the structure unobstructed, and certain items need to be removed or sealed to ensure they aren't affected. Taking preparation seriously means a smoother process and a more effective result.
Your termite company will provide a preparation checklist specific to their process — always follow their instructions as the authoritative guide. This post is designed to give you a thorough overview so nothing catches you off guard.
One Week Before Fumigation
✅ Arrange accommodations for your household. You'll need to be out of your home for approximately 72 hours — sometimes longer depending on scheduling. Make hotel, family, or short-term rental arrangements well in advance. Don't leave this to the last minute, especially during busy summer months.
✅ Make arrangements for pets. All pets — including fish, reptiles, birds, and any other animals — must leave the home. Dogs and cats can stay with friends, family, or a boarding facility. Fish tanks require special attention (see below). Birds are particularly sensitive and should be relocated well before fumigation day.
✅ Set up a drop off for your Nylofume bags. Your termite company will provide special Nylofume bags for sealing food and medications. We will drop these off in advance so you have time to pack items properly. Don't substitute regular plastic bags — Nylofume bags are specifically designed to be impermeable to the fumigant.
✅ Notify your neighbors. Give neighbors advance notice, particularly those in attached or very close properties. Your termite company may assist with this, but a personal heads-up is always a courteous step.
✅ Arrange for mail and deliveries to be held. Contact USPS to hold your mail and pause any regular deliveries for the duration of your absence. An unexpected delivery during fumigation can create complications.
Two to Three Days Before Fumigation
✅ Pack and seal all food, drinks, and medications. Any opened food items, beverages, medications, vitamins, supplements, and pet food need to be either:
Removed from the home entirely, or
Sealed in Nylofume bags provided by your fumigation company
Factory-sealed cans, bottles, and jars with intact original seals are generally safe to leave. When in doubt, bag it or remove it. This includes items in the refrigerator and freezer — opened packages should be bagged.
✅ Remove or protect plants. Most plants can remain in the home but should be thoroughly watered the day before fumigation — well-hydrated plants tolerate the process better. However, any particularly valuable or sensitive plants are better moved outside or to another location if possible.
✅ Handle your fish tank. Fish tanks require the aerator pump to be turned off or the fish to be relocated. Discuss your specific setup with your fumigation company in advance — they can advise on the best approach for your tank size and fish species.
✅ Remove or seal specialty items. A few categories of items are worth special attention:
Mattresses with plastic covers should have the covers removed or opened — plastic can prevent the fumigant from penetrating
Waterbeds — consult your fumigation company for specific guidance
Opened tobacco products should be removed or sealed
The Day Before Fumigation
✅ Unlock all interior doors, cabinets, and access points. The fumigant needs to reach every area of the home. Leave all interior doors open — including closet doors, cabinet doors, and any interior access panels. Unlock and open attic access hatches. The goal is unobstructed airflow throughout the entire structure.
✅ Remove all people and pets from the home. Confirm that everyone — family members, pets, and any houseguests — has vacated the property before the fumigation crew arrives.
✅ Double-check your Nylofume bags. Make sure all food, medications, and consumables are properly sealed. This is worth a final walkthrough — kitchen pantry, refrigerator, bathroom medicine cabinet, bedside tables, and any other spots where food or medication might be stored.
✅ Take valuables and irreplaceable items with you. While the fumigant doesn't damage belongings, it's good practice to take irreplaceable documents, jewelry, and other valuables with you for the duration.
Fumigation Day: What to Expect
On the day of fumigation, the crew will arrive and complete the following:
Conduct a final walkthrough to confirm preparation is complete
Place warning agent (chloropicrin) and begin sealing the tent
Drape and seal the tent around the entire structure
Introduce the fumigant (sulfuryl fluoride) into the sealed structure
Place monitoring devices inside to measure fumigant concentration
You don't need to be present for fumigation day — in fact, you shouldn't be. Stay away from the property until you receive official clearance.
Returning Home: What to Know
✅ Wait for official clearance. Do not return to your home until your fumigation company has tested the air quality inside and issued written clearance. This is non-negotiable — clearance testing ensures fumigant levels have dropped to safe standards before re-entry.
✅ Ventilate the home upon return. When you return, open windows and doors to allow fresh air to circulate. The fumigant will have dissipated, but airing the home out is a good first step.
✅ No need to wipe down surfaces. The fumigant is a gas — it doesn't leave a residue on surfaces, furniture, or fabrics. You don't need to wash dishes, wipe counters, or clean upholstered furniture as a result of fumigation.
✅ Remove Nylofume bags from food items. Food sealed in Nylofume bags can be unsealed and returned to normal storage once you're back home.
✅ Reconnect fish tank aerator. If your fish remained in the tank during fumigation, reconnect the aerator pump as soon as you return.
The Bottom Line
Fumigation preparation has a lot of moving parts, but working through it methodically — starting a week in advance — makes the process straightforward. The key is not leaving things to the last minute, following your fumigation company's specific instructions, and making sure your household is safely out of the home before the crew arrives.

Frequently Asked Questions: Preparing for Termite Fumigation
How far in advance should I start preparing for termite fumigation?
Starting one week before your fumigation date gives you plenty of time to arrange accommodations, pick up Nylofume bags, pack food and medications, and handle any landscaping that needs trimming. Leaving preparation to the last day or two creates unnecessary stress and increases the chance of overlooking something important.
Do I need to wash my dishes or clean my house before fumigation?
No special cleaning is required before fumigation. The fumigant is a gas that doesn't interact with household surfaces in a way that requires pre-cleaning. After fumigation, you also don't need to wipe down surfaces — the gas dissipates completely and leaves no residue.
Can my houseplants stay inside during fumigation?
Most plants can remain inside during fumigation. Water them thoroughly the day before to help them tolerate the process. Particularly valuable or delicate plants are better moved outside if possible. Confirm with your fumigation company for any specific guidance on your situation.
What happens if I forget to seal something in a Nylofume bag?
If you realize after the fumigation has begun that you forgot to seal a food item, the safest approach is to discard it when you return home. While the fumigant dissipates from the air, it's not worth the risk with food items that weren't properly sealed. When in doubt, throw it out.
Do I need to remove artwork, electronics, or clothing?
No. The fumigant is a gas that doesn't damage artwork, electronics, clothing, furniture, or other household items. You don't need to remove or cover these items. The main categories requiring action are food, medications, and plants.
How will I know when it's safe to return home after fumigation?
Your fumigation company will test the air quality inside your home using a specialized meter after the aeration period is complete. You will receive written clearance confirming that fumigant levels have dropped to safe standards before you are permitted to re-enter. Never return to a fumigated home without this clearance.
