The Warning Signs
“HWA is capable of explosive rates of population increase” – Dr. Carole Cheah
HWA is dangerously communicable. It spreads from tree to tree, property to property, forest to forest and beyond. The woolly egg sacks open releasing hundreds and thousands of crawlers that fall like sand and blow in the wind, are carried by birds and drop onto other animals, people and objects. Any medium is capable of transferring the pest from tree to tree. The results are catastrophic. Discolored and falling needles are just the first signs that your trees are in serious trouble.
