Quick facts on EAB from Purdue
-Every year EAB grows by 5000%
-Trees are dead within 2-5 years of infestation
-Early signs, (2-3 years) are very difficult to detect even by professionals
-90% of the beetles life cycle is inside the wood under the bark
-Trees with low density infestation have virtually NO symptoms
-It spreads exponentially. One mating pair will develop 8.1 million eggs in 4 years
**According to Purdue researchers: 1st year 1% of trees dead. 2nd year 2% of trees dead. 3rd year 4% dead. 4th year 8% dead. (This is the stage when people begin to notice an infestation problem when about 1/10 ash are dead.) 5th year 16% dead. 6th year 32% dead. 7th year 64% dead. 8th year 100% dead ash trees. So in essence, once signs are seen, all untreated ash trees will be dead in the area within 4 years.
