Ground Zero for Emerald Ash Borer
Tree Service in Cranberry Township has a piece of history attached. In June 2007, federal survey crews checking ash trees along the Pennsylvania-Ohio border collected two beetles from trees in a commercial parking lot in Cranberry. They were confirmed as emerald ash borer, the first detection of the pest in Pennsylvania. Follow-up surveys on a one-mile grid within 5 miles of the find turned up the beetle in about 30 of 98 grid squares.
What that means for Cranberry yards now
Nearly two decades on, untreated ash in and around Cranberry are mostly dead or gone. The ones that remain are often in back-lot tree lines, along Brush Creek and on common ground in older subdivisions. Dead ash dries out and gets brittle quickly, which makes climbing them risky; many have to be taken down with a lift or by careful felling. If you still have a living ash in the yard, it has survived either by treatment or by luck, and it's worth having it looked at.
Built fast, planted young
Cranberry was farm country until the Pennsylvania Turnpike's western section opened in 1951. I-79 followed in 1966 and I-279 in 1989. The population went from 4,873 in 1970 to 23,625 in 2000 and 33,096 in 2020. Most yards were planted from scratch, often with the same few fast-growing species, such as Bradford pear, red maple and white pine. Those trees are now 20 to 40 years old, and the pears in particular split apart in wind and ice because of their narrow branch angles.
What the curbside pickup takes
The township's yard waste collection runs from April into early December on regular collection days, using the green-top cart or paper bags. It takes brush, tree trimmings and branches under 4 inches in diameter. Limbs over 4 inches, stumps and firewood are not accepted. So small pruning debris can go out with the cart, but a removal needs a plan for the wood. Our estimate states whether we chip and haul, leave logs, or both.
Spotted lanternfly reached Butler County too
The state added Butler County to its spotted lanternfly quarantine before the 2023 spring hatch. Tree-of-heaven, the insect's favorite host, grows along roadsides and in disturbed ground near new development. We point it out when we see it on a property.
Common Cranberry jobs
- Dead ash removal from yards and back tree lines
- Removing split or overgrown Bradford pears
- Thinning and raising white pines and spruces planted as screens
- Stump grinding after removals, with grindings hauled or left as mulch
Commercial and HOA ground
Many Cranberry neighborhoods have common areas managed by a homeowners association. If a dead tree sits on common ground behind your lot, the HOA usually has to approve and pay for its removal. We can quote the work for the HOA directly, or give you a written assessment to bring to the board.

Cranberry Township Questions
Can I put tree limbs out with my yard waste cart?
Only smaller ones. Cranberry's collection takes branches under 4 inches in diameter, in the green-top cart or paper bags. Bigger limbs, stumps and firewood aren't accepted, so larger tree work needs its own cleanup plan.
My ash tree still has leaves. Is it worth saving?
Maybe, if it has been treated or the crown is still full. An ash that is losing a third or more of its crown is usually past saving. We'll tell you which category yours falls in.
Why do Bradford pears keep splitting?
They grow many branches from nearly the same point at narrow angles, which makes weak joints. Pruning young trees helps a little, but older pears that have started splitting are usually best removed.
Is it worth treating a healthy ash tree in Cranberry?
For a valuable shade tree that still has a full, healthy crown, treatment can keep it alive, but it has to be repeated. For ash with significant dieback, or ash in a back tree line you don't care much about, removal is usually the more practical choice.
