The Shield Pest Solutions can help you to eliminate bed bug infestations of any severity with our four part treatment plans. We’ll begin by thoroughly vacuuming every crack and crevice, followed by a spray treatment and dust treatments. Your home can then be accessed after the spray treatment dries, which typically takes between 25 minutes to 3 hours, depending on the severity of your problem. See our ” BED-BUG Prep list ” on our news page.
