Over the years since the release of our book and DVD (Nature’s Mold Rx, the non-toxic solution to toxic mold, and Toxic Mold, A Breakthrough Discovery) variations of the following three questions have come up quite often:

1.  How do I find a qualified professional to do mold sampling?

2.  When a qualified professional is located, what do I say to him or her?

3.  What if the sampling professional recommends one of the remedies you’ve exposed as dangerous and/or ineffective, like fogging with toxic chemicals, using bleach, ozone, or ultraviolet light?

One of the most serious mistakes anyone can make with mold is to underestimate the dangers presented by exposure specifically to toxic mold or any mold that presents a health hazard. The importance of finding a qualified professional who can take the appropriate samples and interpret the laboratory results cannot be overstated because they can help you understand the risks and help you understand appropriate actions that will allow you to avoid getting sick.  

The Close Protocol to Prevent and Eliminate Mold is a proven solution to preventing and eliminating mold on surfaces as well as in the air. However, because most professionals are still not familiar with it, they cannot recommend it. We are working to get the Close Protocol more widely accepted and understood. Until it becomes a common methodology, we suggest that you hire someone to do sampling, and either undertake the remediation yourself or find a contractor who will work with you and/or Dr. Close to remediate your mold problem.

We discuss at length how to find a qualified professional in our Book, Natures Mold Rx. However, we will include the answer in this discussion again because we feel it is important to make this information available through multiple venues.

Question Number 1: How do you find a qualified professional sampler? 
o   Contact the Indoor Air Quality Association (IAQA) and ask for referrals to qualified professionals in your area. They have a list of members available to the public. Their website is:
o   Locate an environmental consulting or environmental engineering firm that specializes in indoor air quality. Engineers take a more thorough approach than mold remediators and they are less likely to be doing remediation. So, they will be an independent third-party that can perform testing without an agenda.
o   Contact a professional Industrial Hygienist. Here is a searchable list of consultants and professionals offering Industrial Hygiene specialists:
o   Contact the local Public Health Department and ask for referrals to qualified professionals in your area.  NOTE:  Care must be taken when contacting the Public Health Department. If the Health Dept sends technicians out to sample, and they find toxic mold, they may quarantine your home or apartment and require that you destroy everything in it, as happened in one of the cases cited in our DVD.
o   Contact a local university or one in your state that has an environmental science or engineering program. Ask if they do sampling or know a qualified professional that does.
o   Be sure to ask to see the sampling technician’s credentials.

The question above is addressed at length in our book, Nature’s Mold Rx, the non-toxic solution to toxic mold. For additional information, we refer you to Chapter 7, page 149. If you do not have a copy of the book, you can purchase it at this link: 

Question Number 2: When a qualified professional has been located, what are the questions you should ask that person?

  1. How long have you been doing mold sampling?
  2. What type of training and credentials do you have?
  3. What type of samples will you collect?
  4. Do you provide a report, a copy of the sample analyses, and an explanation of the findings?

When the professional comes and samples, they will then explain the results and offer suggestions as to how you should proceed. This question is also covered in Chapter 7 of our Book, Nature's Mold Rx.

Question Number 3:  What if the sampling professional recommends something other than the Close Protocol for Preventing and Eliminating Mold?

The Close Protocol uses essential oils to eliminate the dangers of toxic mold. This was first discovered by Dr. Close in late 2005, however, the protocol is still considered a new, cutting edge discovery that most environmental professionals are not familiar with and, therefore, they cannot provide any advice about the Close Protocol. Often they will have their own favorite remedy, which will almost certainly not be as safe or as effective. For this reason alone, we strongly suggest that you thank them for their help and their opinions, and tell them you will give their recommendations consideration. If you have questions about what to do, then Dr. Close is available to help with your project. Simply click on this link:


The effectiveness of the Close Protocol has been proven in tests performed and documented with scientific data collected for the past 8 years, so it is now a well-proven method that offers tremendous benefits without the negative side effects of most standard mold remediation technologies. Also, other mold remediation methods are typically at least 3 times more costly than using the essential oils. So, when you have located someone who has the credentials, experience, and equipment to do a proper job of sampling, you can avoid unnecessary expense by doing the following:

  1. Make sure the sampler takes at least one indoor and one outdoor spore-trap air sample, so you will know what is growing inside the building. See our book or DVD for other sampling methods that may be appropriate to your situation.
  2. Start diffusing Thieves essential oil blend immediately after the samples have been collected. Do not diffuse before the samples are collected, because this will affect the results of the sampling. Be sure to check out our latest recommendations for diffusing at this link:
  3. Ask for a written report identifying the mold species growing in the building.
  4. If the sampling company does remediation or recommends someone, politely thank them and tell them you will consider their proposal for additional work.
  5. If there is no toxic mold present, then diffuse the Thieves oil blend for 24-72 hours and use Thieves Household Cleaner to clean the infested area.
  6. If toxic mold is found, then be certain to diffuse the Thieves oil blend for a minimum of 24-72 hours in the areas where the mold was found.
  7. After the intensive diffusing, contact your professional again, tell them you have used a solution of essential oils to eliminate the mold, and you would like to have them come and re-sample to find out if toxic mold is still present in the air.
  8. Discuss the results with your professional, refer them to the and the book, Natures Mold Rx. Develop a plan for appropriate cleanup and removal if any remaining mold sources of infestation are identified. If you have Toxic Mold, you will definitely need the professional’s help to identify the source of the infestation, the areas where leaks or moisture are creating the conditions necessary for mold growth, and in removing and disposing of toxic mold contaminated materials. If you do not have a mold that is known to be toxic and potentially hazardous, then you can save yourself a tremendous amount of money by doing a lot of the cleanup yourself.
  1. After cleanup and removal are complete, we strongly suggest that you continue diffusing the Thieves oils blend regularly, on a much more limited basis, in order to prevent mold from re-establishing itself.

In summary, these are 4 important points to keep in mind:

  1. You have available in the Close Protocol the very best remedy available today. Using Young Living Therapeutic Grade Thieves Essential Oil and Thieves Household Cleaner is not only more effective, (see data available at and in our book, Nature’s Mold Rx) but it is also non-toxic and actually provides many documented benefits to your health.
  2. Have a qualified professional do the sampling. Don't use gravity samplers or mold sampling kits. They are a waste of money and will almost always identify some mold, but do not give you a true picture of what molds are in your environment.
  3. If you have a professional service do the cleanup, do not accept the use of bleach, chlorinated petrochemicals, or any other toxic chemicals. You have rights and if the contract is not willing to work with you and use the recommended cleaners, then you will be best served looking for another contractor.
  4. If you do any of the cleanup yourself, be sure to obtain the proper protective equipment.
The Close Protocol to Prevent and Eliminate Mold has been used in homes, hospitals, schools, restaurants, by public and government agencies with more success than any other mold remediation option currently available.

May You Live in Joy and Vibrant Health!
