The typical total cost for a new septic system over a 20 year period is $6,300 to $13,000 for trenches and mounds, or $13,500 to $32,000 for alternative treatment systems. For multi-household systems, typical trench or mound systems range from $18,500 to $25,000.
Cockroaches are persistent and troublesome pests of homes, restaurants, hospitals, warehouses, offices, and other structures with food handling areas. These insects contaminate food and utensils, destroy fabric and paper products, and impart stain and odor to surfaces they contact.
It depends on the species, but cockroaches can live for weeks without their head. Eventually they starve to death because they have no mouth, though they probably get eaten or killed pretty fast anyway because they lose a couple senses. They are able to do this because their brain isn't as centralized as ours.
