How to Prepare for Termite Fumigation Before the Tent Goes Up

The tenting date is on the calendar, the hotel is booked, and now you’re staring at your kitchen wondering which of these things actually has to go in a bag — the sealed cans? The dog food? The bottle of vitamins? Somewhere between the instruction sheet your fumigator handed you and the pile of groceries on the counter, a little panic sets in. Get the prep wrong and the crew can’t start, the job gets rescheduled, and you’ve burned a hotel night for nothing.

Here’s the reassuring part: the prep is very doable once someone lays it out plainly. Knowing how to prepare for termite fumigation really comes down to a handful of categories — food and medicine, plants and pets, opening the house up, and access — done in the right way. Let’s walk through the complete checklist step by step so your tenting goes smoothly the first time, with the safety notes that matter most.

Quick Answer

What has to be bagged? Opened food, medicine, supplements, pet food, and similar items go in the fumigation (Nylofume) bags your company provides. Factory-sealed cans and bottles are generally fine.

Do plants and pets leave? Yes — all people, pets, fish, and houseplants must be out for the entire fumigation and aeration period.

What do I open? Interior doors, cabinets, drawers, closets, and appliance doors, so the gas circulates everywhere.

What about outside? Water the soil around the foundation and move potted plants a couple of feet from the walls, as your fumigator directs.

Who has the final say? Always your licensed fumigator and the product label. Call Termike at (888) 683-3592.

Follow Your Fumigator's Instructions and the Product Label

This is a general prep guide. Fumigation uses a restricted-use gas, so the instructions your licensed fumigator gives you — and the product label — always take priority over anything here. Follow their exact bagging, access, and re-entry directions, and never re-enter a tented or recently fumigated home until the company has aerated it and cleared it for occupancy.

How to Prepare for Termite Fumigation Step by Step

Fumigation works by filling a sealed, tented structure with a gas that penetrates deep into the wood to eliminate Drywood termites throughout the home. Because that gas gets everywhere, your prep has one underlying goal — let the gas reach all the wood while keeping it away from anything you’ll later eat, take, or bring back inside. With that logic in mind, here’s how to prepare for termite fumigation the right way.

1.     Bag or remove food, medicine, and consumables. Anything opened or able to “breathe” — opened food, produce, medications, supplements, pet food, tobacco — goes into the sealed fumigation (Nylofume) bags your company supplies, or leaves the house with you. Factory-sealed cans, bottles, and jars with the original seal intact are generally fine, but follow your fumigator’s specific list

2.     Open the house up inside. Open every interior door, cabinet, drawer, closet, and appliance door (oven, refrigerator, washer, dryer). The gas needs a clear path into every space, so nothing should be sealed shut on the inside

3.     Get all living things out. Every person, pet, and plant must leave — dogs, cats, birds, reptiles, and fish tanks included. Arrange boarding or take them with you. Nothing alive stays in a tented home

4.     Handle plants and landscaping. Remove indoor plants entirely. For plants and shrubs touching the house, your fumigator will usually have you trim them back and water the soil around the foundation thoroughly — moist soil helps protect roots and create a seal at the tent edge

5.     Arrange access and keys. Unlock gates, provide keys or a lockbox, disarm security systems, and confirm the crew can reach every entrance. Turn off gas pilot lights and appliances if your company directs — many coordinate shutoff with the gas utility

6.     Plan your time away. Confirm exactly how many nights you’ll be out so lodging lines up with the aeration and clearance schedule — treatment plus aeration typically spans a couple of days. Termike’s guide on moving back in after termite fumigation covers re-entry timing

7.     Confirm the details with your fumigator. Every company’s prep sheet varies slightly. Treat their written instructions as the final word and call them with any “do I bag this?” questions before the day arrives

How to Prepare for Termite Fumigation in the Kitchen

 

The kitchen causes the most confusion, so it’s worth its own moment. The simplest rule for how to prepare for termite fumigation in the kitchen is “if it’s open or can breathe, bag it or remove it.” That means opened boxes and bags, produce on the counter, anything in the fridge or freezer that’s been opened, spices, and pet food all go into the provided fumigation bags or leave with you. Factory-sealed metal cans and glass bottles with intact seals generally don’t need bagging, but when in doubt, bag it — over-bagging is harmless, while under-bagging is not. If you want the deep-dive on exactly which items need sealing, that gets its own full guide in this series.

According to the U.S. Environmental Protection Agency, sulfuryl fluoride — the gas most commonly used for structural termite fumigation — requires specific safety handling, which is exactly why food and medicine protection and professional aeration before re-entry aren’t optional steps.

What Not to Do

A few avoidable mistakes cause most of the rescheduled jobs and day-of headaches. Steering clear of these keeps everything on track.

•       Don’t skip the bagging to save time. Unbagged consumables are the number-one reason a job gets delayed or items get thrown out. When unsure, bag it

•       Don’t leave pets or fish “just for a few hours.” There is no safe window — every living thing must be out for the entire period

•       Don’t leave interior doors or cabinets closed. Sealed-off spaces can keep the gas from reaching wood that needs treatment

•       Don’t re-enter early. Never go back into a tented or recently fumigated home until the company has aerated it and officially cleared it. Termike’s guide on whether it’s safe to go back inside after fumigation explains why that clearance step is non-negotiable

•       Don’t assume tenting is always required. For some infestations a local treatment is an option. Termike’s guide on whether you really need to tent your house is worth reading before the tent even goes up

Why Proper Prep Matters So Much

It can feel like a lot of fuss, but each step ties directly to either safety or results. Protecting food and medicine keeps the fumigant away from anything you’ll ingest. Getting living things out protects your family and pets. Opening the house ensures the gas actually reaches the termites, so you don’t pay for a fumigation that misses pockets of the infestation.

Fumigation is a powerful, whole-structure solution precisely because the gas goes everywhere — and that same reach is why the prep is strict. The University of California Integrated Pest Management Program notes that whole-structure fumigation is used to eliminate drywood termites throughout a building, reaching galleries that spot treatments can’t. Termike’s overview of the benefits of fumigation explains why that whole-home reach is the point. For the other side of the process, the termite fumigation aftermath checklist picks up where this guide leaves off.

The Bottom Line

Prepping for a tenting job feels overwhelming right up until someone sorts it into categories — and then it’s just a checklist. The whole of how to prepare for termite fumigation comes down to five things: bag or remove anything you’ll eat or take (opened food, produce, medicine, supplements, and pet food go in the sealed fumigation bags, while factory-sealed cans and bottles are generally fine), open the house up inside so the gas circulates through every door, cabinet, and appliance, get every living thing out for the entire period (people, pets, fish, and houseplants, with no exceptions), handle plants and water the soil as your fumigator directs, and arrange access, keys, and your nights away. Steer clear of the classic mistakes — skipping the bagging, leaving a pet “just for a few hours,” sealing cabinets shut, or re-entering before the home is aerated and cleared — and the job goes smoothly the first time. Above all, treat your licensed fumigator’s written instructions and the product label as the final word, because fumigation uses a restricted gas and their directions always outrank a general guide. Do the prep right and you come home to a termite-free house with nothing lost along the way.

Frequently Asked Questions

What exactly do I need to bag before termite fumigation?

The guiding rule is: if it's opened or can 'breathe,' bag it or remove it. That covers opened food, fresh produce, anything already opened in the fridge or freezer, spices, medications, vitamins and supplements, pet food, and tobacco — all of which go into the special fumigation bags (often called Nylofume bags) that your company provides, or leave the house with you. Items in their original factory seal — unopened metal cans, sealed glass bottles and jars — generally do not need bagging, because the intact manufacturer seal keeps the gas out. That said, every fumigation company provides its own specific list, and if you're ever unsure about a particular item, bag it: over-bagging costs you nothing, while leaving something unbagged that should have been sealed can mean throwing it out. Double-bag medicines and anything you're especially cautious about. This series includes a dedicated guide on exactly what to bag if you want the complete item-by-item breakdown.

Do my plants and pets really have to leave for termite fumigation?

Yes — without exception. Every living thing must be out of the home for the entire fumigation and aeration period, and that includes people, dogs, cats, birds, reptiles, fish in aquariums, and all houseplants. There is no 'safe for a few hours' window, because the fumigant gas fills the entire sealed structure. For pets, arrange boarding or take them with you; don't leave a fish tank behind assuming the water protects them, because it doesn't. Indoor plants should be removed entirely rather than bagged. For outdoor plants and shrubs that touch the house, your fumigator will typically have you trim them back from the walls and water the soil around the foundation thoroughly — the moisture helps protect the roots and improves the seal at the edge of the tent. Always follow your specific company's instructions on landscaping, since the details vary by home and by the plants involved.

How long do I need to be out of the house for fumigation?

Plan on being out for roughly two to three days in most cases, though your fumigator will give you the exact window for your home. The timeline has two parts: the hours the structure sits under the sealed tent with the gas working, and the aeration period afterward, when the company ventilates the home and tests the air until it's safe to re-enter. You cannot go back in until the company has completed aeration and officially cleared the home for occupancy — this clearance step is a safety requirement, not a formality. Because weather, home size, and dosage all affect the schedule, confirm the number of nights before you book lodging so your return lines up with the clearance, not a guess. When you do come back, there's a short re-entry process worth understanding, which this series and our moving-back-in guide cover. If anyone ever pressures you to re-enter early, don't — wait for the official clearance.

What happens if I don't prepare correctly for the fumigation?

Two things, depending on what you miss. If the prep isn't done when the crew arrives — consumables not bagged, cabinets closed, living things or plants still inside, access not arranged — the job usually can't proceed safely and gets rescheduled, which can cost you another hotel night and a delay in solving the termite problem. If prep gaps aren't caught, the consequences are worse: unbagged food and medicine can be exposed to the fumigant and must be discarded, and sealed-off interior spaces can keep the gas from reaching wood that needs treatment, leaving pockets of the infestation alive. That's why the categories matter — bagging protects what you'll consume, opening the house ensures the treatment actually works, and removing living things protects your household. The simplest safeguard is to follow your fumigator's written checklist exactly and call them with any questions before the day arrives.
