There’s a silver lining to this extreme weather — hemlock woolly adelgids might die forever!! Fingers crossed for the sake of our hemlock trees! 🤞🏻
We can probably all agree that this frigid weather has the potential to negatively affect our health. On the bright side, it also negatively impacts the survival of HWA! Research indicates that prolonged periods of subzero temperatures (specifically -4°F and below) can cause HWA mortality by up to 90% in some cases. Prolonged instances of temperatures ranging from -22°F to -31°F may cause a near total collapse of HWA populations. So while you're sitting by your wood stove or relaxing under a heated blanket, remember that the HWA outside is having a far worse day than you are.
