HOMEOWNERS GUIDE

How much Vikane fumigant will be used?
All of the following factors are calculated on the “FumiCal” to determine the amount of Vikane fumigant that will be used in the fumigation.

Volume (size of structure)- Calculated by the estimator by measuring the dimensions of the structure.
Wind - The approximate velocity of the wind is determined at the time of the fumigation.
Seal - The condition of the seal where the tarp meets the ground is determined to be good, fair or poor.
Under Seal- Type of seal at the bottom of the house, whether it is a concrete slab, loam soil, sandy soil, etc.
Temperature -The approximate temperature is determined at the time of the fumigation.
Exposure Time -How long the structure will be covered.  Average time of cover is approximately 16-20 hours.  The shorter the length of exposure, the more Vikane fumigant is used.

AFTER THE FUMIGATION DON’T BE ALARMED IF:
If you see ants or roaches in the house after the fumigation.  The fumigant is a gas and does not leave any residue.  Insects can enter the structure after the fumigant is evacuated.  Ants in particular are attracted to the dead termites and other insects that were killed in the structure during the time of the fumigation.  Geckos can survive the fumigation due to its greater tolerance to the fumigant.  Remember that the target is drywood termites.
Swarming termites can enter the structure after the fumigation.  The swarmers usually come out during humid, windless evenings and are attracted by the lights in the structure.  The swarmers find their way into the house from the windows, doors or any opening.

OUR MONITORING EQUIPMENT
The RDA (Remote Data Acquisition) Fumiscope provides remote monitoring and measuring of the gas density of various fumigants.  We use this unit to ensure safe deployment of the fumigants as well as to monitor the proper amount of fumigant is being used.
