Maki Pellets and other Rodent Exterminating Products.
Before using any mouse/rat control substance it is important to take measures to mouse-proof the property. Make sure all open area’s (holes, gaps or cracks) are sealed. Any of these openings are an invitation to rodents. Make sure that all food is covered tightly. Remove any crumbs or food tid-bits. Place all food in upper cabinets rather than the lower ones.
