Avoid a void

A void is typically defined as an uninhabited area.  Well, we might say "allegedly" uninhabited.  Even your dining room banquet seats can have large empty spaces where invaders (space invaders?) can dwell, find harborage, and cause damage to your goods and reputation.

All voids need to be inspected and treated regularly.  Every void should have:

1) Visual inspections
2) Monitoring systems in place
3) If necessary, traps to catch and / or kill active pests
4) If necessary, products to eliminate active pests.

You can't avoid having voids in your locations, but you can avoid many of the problems if you purpose to reclaim these "unvenued spaces."
