Pesticide strips used to control parasitic mites in honeybees. The pesticide strips are designed to have a lifetime or period of existence, after which the strip no longer exists in its original form. The strip breaks down, such as by disintegration, dissolving, decomposition, being eaten or carrier away, or otherwise degrading over time, so that at the end of the recommended lifetime, the strip is no longer in its original form. In most embodiments, at least 50% of the strip is no longer present, and in other embodiments at least 75% of the strip is no longer present. Preferably, at the end of the recommended lifetime, the strip no longer exists, at least the body of the strip that included the active ingredient. With this design, the strip does not provide extended low-dose pesticide that can be detrimental in treating the mites.
