The subject invention provides materials and methods for the control of pests. The voltage divider allows for adjustment of the trigger voltage, trigger current, and holding voltage of the protection circuit so that the protection circuit can conduct current after a particular voltage level has been applied to the protection circuit without accidental triggering on by, for example, noise. A first MPLB component associated with a first network device sends a latency request packet, including a first timestamp provided by a first clock associated with the first MPLB component, to a second MPLB component associated with a second network device via the path. At the pleating station the roll is creased successively to form a plurality of pleats and the direction in which the creasing proceeds is such as to facilitate the escape of air from the roll as it is pleated.
