Q&A
What is the shelf life of your BTK Insecticide concentrate?
Question by: R Scott on May 26, 2024, 6:05 PM
This product should be used within 2 years of the manufacture date for best results.
Answer by: Lauren Potter (Admin) on May 28, 2024, 10:31 AM
in follow up to my previous question, Safer's has indicated that the date of manufacture should be read as year, day, month, ie: LBL172110 is 2017, 21 day, 10 month. so according to the MSDS sheet this product would've expired (or should be used before) October 21, 2019.

Hi, thank you so much for your comment! We’d be more than happy to assist you with this matter. Please call us at 1-855-767-4264.

Please clarify your manufacturing date code and edit your previously answered questions about this appropriately. Some answers say mm/dd/yy others say year day month and another says it’s just a product revision date. The same answers also say 2 year effectiveness and another says no loss in effectiveness if stored correctly. All very confusing.
Question by: Craig on May 24, 2025, 9:13 AM
Hi, thank you for reaching us. The label should be read as month, day, and year. Store product between 0 degrees C and 20 degrees C to maintain optimal stability/longevity. As long as the product has been stored appropriately, there is no concern for reduced efficacy as a result of shelf life. Once the container is opened, the shelf life will be approximately one year.

If using hose end Sprayer what setting do you use for BTK
Question by: Margaret P. Guist on Jun 4, 2026, 12:20 PM
Thank you for contacting us. For hose-end sprayers the dilution rate should be 1 part concentrate to 30 parts water.

Ok. I've read all the explanations about date of manufacture and still can't tell when the Safer bt that I bought online last year was manufactured. My label reads LBL5163F-2 0517. When was it manufactured?
Question by: Ted Carlton on Jun 27, 2026, 4:41 PM
Thank you for contacting us. Regarding your question, BTK can be used for up to 2 years from its manufacturing date. The manufacturing code starts with a letter, for example “A040122” (April 1st, 2022). This code is printed on the back of the bottle so you can determine when it was manufactured.
