Sort Questions
Does Pyranha Stock Guard have any residual period or is it immediate use only?

In reading the instructions for poultry application, I noticed that it does not state to repeat in 10 days for newly hatched eggs. Does that mean it has a residual period?


Pyranha Stock Guard only kills those insects that are out in the open and come into contact with it at the time it is being applied.  There is no residual kill, but it can potentially make an area slightly repellent for 2-3 days after an application.  We do not find any reference to newly hatched eggs on the product label, so you may wish to contact the manufacturer Pyranha with specific application questions directly at 1-800-231-2966, or via their contact page here.
