In addition, below is a great suggestion posted by a friend of mine on Facebook:
Please help
me get the word out. If you've got Spotted Lanternflys and you just don't know
what to do about them get this fly tape! It's called Catchmaster Giant FlyTrap. It is exactly that, a giant 10-inch wide, 30-ft long roll of fly tape.
Nothing to spray, don't have to worry about kids or pets getting near it and it
certainly will not contaminate your property with insecticides!

Every time I
am out replacing the tape (because the last one was filled), people driving by
pull over and ask what it is, does it work, and where they can get it. I
originally purchased them at TSC in Gilbertsville. Needing more, I found that HomeDepot.com
sells them for the same price $6.99 per roll. I ordered 7 to get to the free
shipping amount ($50) and they arrived soon after.
PLEASE share
this information. They are an invasive insect with no natural predators here
and they continue to spread. They suck sap from trees and slowly kill them.
This insect has the potential to greatly impact the grape, hops, and logging
industries.
Penn State Extension Update on Control Options, September 1, 2017
As
the result of a mild winter, the Spotted Lanternfly (Lycorma delicatula)
population is enormous this year. In many areas in early August, trees were
completely covered with feeding nymphs. Unsurprisingly, reports of Spotted
Lanternfly from locations previously considered uninfested are significantly on
the rise in southeast Pennsylvania.

There
is limited information on pesticide options for control of Spotted Lanternfly
because is it a new pest to this area. This year, Penn State Extension is
conducting efficiacy trials on products that are available to the homeowner for
control on their property. Early this month, we began testing contact
insecticides including horticultural oil, neem oil, insecticidal soap, and
products that contained spinosad, carbaryl, bifenthrin, or pyrethrin as the
active ingredient. Additionally, we included two systemic insecticides (both
applied as soil drenches and one as a bark spray) in our preliminary trials.
Our
initial observations suggest that some active ingredients produce better
control than others. For those products with active ingredients of bifenthrin,
pyrethrin, and carbaryl (from what was tested so far), we saw an immediate
effect on caged lanternflies (see image above). There was some effect from neem oil and
insecticidal soap, but results were variable. Also, the insects were not killed
immediately with these products; it took several days to see the full effect.
For the systemic products, the bark spray (active ingredient = dinotefuran)
appears to outperform the drenches (dinotefuran and imidacloprid). We speculate
that the drenches may do better if applied to the soil earlier in the season
and may consider changing our study design for next year. Regardless, our 2017
study is a preliminary effort. Moreover, we have not completed collecting our
data for the season.
Adult
Spotted Lanternflies started emerging in early August. The female lanternflies
are not reproductively mature at emergence. It is believed that they must feed
on the Tree-of-Heaven (Ailanthus altissima) at some point in order to complete
the life cycle. However, it is important to understand that the number of hosts
on which the insect can complete its life cycle is unknown at this time. Other
researchers are involved with determining primary and secondary host plants
from opportunistic/accidental feeding. However, Penn State Extension is also
monitoring the population for general reproductive status in order to adjust
control tactics (if appropriate) to target pesticide applications prior to the
onset of oviposition in the majority of the population in order to make
additional control suggestions that may reduce the population of the following
year.
Always
use pesticides carefully. Read the label to ensure your safety as well as that
of the environment.

Penn
State Extension will continue to provide updates as information becomes
available.
