Preparing for Tent Fumigation

Below are important things to know before tent fumigation occurs

What is Vikane gas fumigant?

Vikane is a colorless, odorless gas that quickly penetrates structural materials during whole-structure fumigation. Vikane, backed by nearly 50 years of university research, practical use and published reports is nonstaining, noncorrosive and nonflammable. Vikane quickly dissipates from the structure into the atmosphere and does not damage the ozone layer.

Will Vikane gas fumigant cause damage to my home?

Vikane gas fumigant does not react with most materials and is unlikely to cause damage. Your licensed, trained fumigation professional will inspect your property to help ensure that your contents will not be affected.

What items do I need to remove from the property?

Anything living: people, pets, including fish, and plants.

Does whole-structure fumigation kill other pests in my home, such as spiders, ants and lizards?

Fumigation professionals calculate the fumigant dosage they use based on the target pest they are eliminating, such as drywood termites. Excellent only guarantees the target pest we are fumigating for.

What food items do I need to bag up?

Excellent provides special Nylo Fume bags to protect food items during the fumigation. The items must be double bagged in the bags provided. Food items to bag up include sealed and unsealed plastic, for example soda and cake mix. In general, any food that is not sealed in glass or metal bottles with the original manufacturer’s airtight seal intact needs to be double bagged in the special bags provided. When in doubt, take it out. It is a good time to clean out the cabinets and fridge.

Do make-up, shampoo/conditioner, and lotions need to be removed?

Make-up, shampoo/conditioner, and lotions DO NOT need to be removed. The gas does not have an odor and does not leave any residue. The gas will not have any chemical reactions with these items.

Do all mattresses have to be removed?

Infant/baby, hospital, and any mattress with vinyl type of fabric covering must be removed from the property. If you have a zipped plastic/vinyl mattress cover, you only have to unzip the end of the cover. The same holds true for zippered clothing bags. They need to be unzipped.

Will plants die under the tent?

Plants will not necessarily die under the tent but we cannot guarantee their survival. We recommend you completely remove the plants from the property. If they cannot be removed, we recommend you water them well the night prior the fumigation, but it is still not guaranteed that they will survive.

Are doors and windows left open?

Doors are left open only when Excellent is there to supervise the property. Windows are left open for proper fume circulation.

Where does the gas air out if my doors and windows are closed?

The gas dissipates on its own with the natural air circulation throughout the property.

Does the gas pocket?

Yes, that is why all drawers, cupboards, trunks, vaults, safes, doors & windows must be opened.

What do you do to prevent pocketing?

We use fans and make sure that all drawers, cupboards, trunks, vaults, safes doors & windows are open.

Do safes need to be left unlocked?

If the safe is big enough to fit a human being inside, we are required to look inside the safe. Yes, the safe also needs to be open during the fumigation. Please remove all personal items prior to the fumigation.

Do I have to notify my neighbors?

Generally, Yes, Excellent will provide a neighbors release to be signed by the neighbors.

How long is the fumigation process?

The fumigation process is a three day process for Drywood Termites and Bed Bugs.

How long does it take to put the tarps on?

It takes approximately two hours to put the tarps on depending on the size of the structure.

How long does it take to remove the tarps?

It takes approximately two hours to take the tarps down depending on the size of the structure.

Where is the key left during the fumigation?

The key will be secured during the fumigation process. Secondary locks will be used to prevent anyone other than our fumigators to enter the property.

Do sprinkler system, automatic light timers, and alarm need to be turned off?

The sprinkler system does not have to be turned off as long as the timer does not go off while we are tenting the property. Automatic light timers must be turned off if the lights are outside so that the tarps are not melted. Alarm systems may be left on but we do need the alarm code if you choose to do so.

Do items around the crawl space, attic area have to be emptied out?

Items do not have to be completely removed but access area to the crawl space or attic must be cleared.

Do antennas or Satellite dishes have to be removed?

We prefer antennas to be removed; however we can tape around the antenna if necessary.

What prep work is required outside?

Remove, trim, or rake back any plants, flower pots, bushes, rocks, branches, etc. that are up against the property at least twelve inches. Antennas are preferred to be taken down and fence boards removed.

How do I prepare my fish aquarium for fumigation?

Removing your fish aquarium from your home is the best possible option. If that cannot be done, it is important to work with your fumigation professional to determine the best way to protect aquarium organisms during the fumigation.

Does ice in the ice maker have to be emptied out when the fumigation is completed?

The ice in the ice maker does not need to be emptied.

Will there be any live termites in my home after whole-structure fumigation?

If you see a few live termites immediately after your home has been fumigated, don’t be alarmed. Sometimes it can take three to five days for all of the termites to die. Rest assured whole-structure fumigation with Vikane gas fumigant will eliminate all of the drywood termites in the home.

What happens to the mail during the fumigation?

The mail will be redelivered after the tents come off the property if the mailbox is connected to the structure.

Is whole-structure fumigation with Vikane a good choice for real estate transactions?

Many title companies require that a home is treated for termites before it can be purchased. Also, most buyers expect the home that they are purchasing is going to be treated.
Whole-structure fumigation with Vikane gas fumigant meets all state and lender requirements for real estate transactions. Whole-structure fumigation is the best drywood termite treatment because it gives both the buyer and seller peace of mind that all of the drywood termite colonies have been eliminated.

Does Vikane gas fumigant negatively affect the ozone layer?

No. Sulfuryl fluoride, the active ingredient in Vikane gas fumigant, is not an ozone-depleting chemical. Vikane contains no chlorine or bromine and, thus, does not deplete stratospheric ozone by the known mechanisms. When a structure is aerated, Vikane rapidly dissipates to non-detectable levels. In 2002 Dow AgroSciences was awarded the Stratospheric Ozone Protection Award by the United States Environmental Protection Agency. This award recognizes extraordinary achievements, international leadership and innovation in preserving the ozone layer.

Why do the fumigators have to go inside the property?

The fumigators must go inside the property to insure no living beings remain inside, and that proper preparation has been done.

Why does the soil around the house have to be watered?

The soil must be watered in order to soak up the roots of the plants on the outside of the property and to help get a better seal when we tent the property.

Does water softening system have to removed or cleaned out during and after the fumigation?

The water softening system does not have to be removed or cleaned out during or after the fumigation.

Why is a roof release necessary?

When performing fumigations it is necessary to walk and or work on roofs of structures. This obviously creates situations where damage to delicate or old roofs can be unavoidable. We do not wish to unnecessarily damage anyone’s property and use our best care to insure minimal damage if any.

How long is the warranty?

The warranty for the fumigation is generally two years depending on pest.

Can cars be left inside the garage?

Cars can be left inside the garage if we have access to the trunk and the doors are unlocked.

Is there a need to wash items following a fumigation?

The gas we use leaves no residue, so washing items is not necessary.

How long does it usually take for a new infestation to appear?

An infestation implies an established colony, and evidence of established colony usually takes three to five years to show, after they have established themselves in a property.
