Re: Diatect International Corporation Gentlemen:

We were not advised by the registrant that the registrant had filed an 8-K on November 5, 2004 terminating Williams &: Webster, P.S. ("Williams & Webster") as its certifying accountant. We became aware of the 8-K filing on Monday, November 8, 2004.

We have read Item 4 of Form 8-K dated November 5, 2004, of Diatect International Corporation and are not in agreement with the statements contained in the first two paragraphs.

Williams & Webster has been unable to complete the review of the registrant's financial statements which were filed for the quarter ended June 30, 2004. The registrant is in violation of Article 10 of Regulation S-X.

Williams & Webster is evaluating its prior reporting relationship with the registrant and, upon completion of the evaluation and recommendation of counsel, may have additional comment or actions.

Very truly yours,

/s/ Williams & Webster, P.S.
