Regional Pest Pressure Guide for Columbus, OH

What this means if you live in Columbus: hardiness zones measure the average coldest temperature an area sees each winter — which directly determines whether insects and their eggs survive the cold season or die off and have to reestablish each spring. Columbus's winters are among the coldest of the 20 cities we track. Real winter die-off means pest activity here is more compressed into a shorter season than in a warmer city — but it doesn't mean zero risk, just a narrower window when it matters most.
