Most chemicals are adversely effected by hot or cold temperatures. The changes in the chemical structure are unpredictable. Since there is no expiration date on pesticides, the only way to know if the product doesn't work is to use it and see. My opinion is that if Termidor freezes and then thaws heats, etc. there will be some adverse effect. However, you don't know unless you use it and it does not work. 3-5 years in the normal lifespan of chemicals such as this in a bottled form.
