What is the approximate minimum gap size requiring sealing for physical Wolf Spider exclusion?

Answer

A quarter of an inch

Physical exclusion is considered the most foolproof defense against wolf spiders because they are wandering hunters that enter structures through openings rather than building webs at entrances. The text specifies that sealing entry points is paramount, focusing specifically on ground-level access. Any fissure, crack, or gap larger than approximately one quarter of an inch should be inspected and thoroughly sealed using appropriate materials like caulk or expanding foam designed for pest control to prevent entry.
