Termite Fumigation Poison Gas Effectiveness




Whole structure poison gas fumigation performed for complete termite eradication is a complex procedure. There are a number of critical steps that must be completely followed, in order to obtain a successful treatment. Commercial fumigators' know the detailed information needed for an effective treatment application to occur.

Most fumigation firms hire experienced, and highly educated, knowledgeable and licensed professionals. However; far too often, these professionals are forced to supervise and delegate the technically skilled responsibilities to uneducated laborers, who end up actually performing many of the important protocol treatment procedures. This is equivalent to, a hospital hiring an apprentice construction laborer to assist in administering anesthesia to patients during surgical operations. Obviously some patients will never wake up, while others will endure unwanted surgery pain. In both instances, the anesthesia administration fails.

Over application of poison gas during fumigation, does indeed effectively kill all the termites, but it also highly increases the risk of poisoning the occupants within days of re-entering the structure treated. Keep in mind, there is no antidote for gas poisoning and it often results in death. Likewise, if the amount of fumigate used is less than the amount labeled as needed, the treatment will not be 100% effective. In most cases, fumigation clients will never know if their fumigation was successful in eradicating the termites effectively, because the termites not killed, stop feeding on wood and instead feed on the carcasses of the dead. The period of carcass consumption can take months, and during that time, there is no longer any wood fecal matter being excreted at areas of prior infestation to indicate an active infestation. Upon completion of the colony carcass consumption, a wood diet will resume and the colony will thrive to reestablish itself.

The following are detailed procedures needed to assure effective termite fumigation. All of these procedures should be strictly adhered to, by an accredited fumigation professional to lessen the risk of treatment failure.

1. Customer should be educated about the fumigation process and all the limitations involved.

2. Properly advise customer and tenant, of all food and non food fumigation preparations.

3. Acquire an accurate cubic footage calculation of the area to be fumigated.

4. Conduct a full assessment of any items that may impact the fumigation.

5. Analyze all the factors that may hinder an effective treatment process.

6. Provide customer written disclosure of anticipated and unfavorable damages that may occur.

7. Offer the customer options to reduce unavoidable potential damages.

8. Employ workers who display strict fumigation treatment disciplines and honest work ethics.

9. Prepare applicable and favorable ground conditions around the structure.

10. Achieve a secure physical attachment of all tarp to maintain a controlled environment.

11. Establish an effective seal at ground level of the fumigation tarp to prevent gas escape.

12. Have a fumigation professional present during all stages of tarp, gas release and aeration.

13. Introduce the correct calculated measured amount of poison gas into the tarp and sealed structure.

14. Assure on site professional's proper use of gas level monitoring equipment.

15. Attain aeration to allow, safe re-occupancy by using a proper functioning gas analyzer.

16. Provide occupant a 24 hour contact phone number during and after job completion.

Whole structure fumigation for termite, has a high level of efficacy when correctly applied. Dry wood termite will die in about 3 days, when exposed to proper poison gas levels. If no evidence of termite becomes visually apparent for a 16 month period after the fumigation, then one can safely assume that the fumigation was effective.
