Top 5 Pests of the Summer Season!

Here are the Top 5 Pests you need to watch for on Trees and Shrubs this summer!

Japanese BeetlesJapanese Beetles

Japanese Beetles can emerge in swarms in June through July.  Once they hit, these annoying, ugly, and damaging pests will feast on your plants through September. Favorite trees and shrubs include roses, flowering cherry, flowering crabapple, linden, and birch. These hungry bugs feed between the leaf veins, so damaged leaf tissue takes on a skeletonized appearance.
It’s important to act quickly if you see Japanese Beetles! Successful control depends on applying treatment when the Beetles are first spotted, and they can do a lot of damage in a little bit of time!  Giroud offers control options for the insect, and the earlier you can get your plants on a program, the better!


Scale attack many different kinds of trees and shrubs, including Azalea, Beech, Holly, Tulip Poplar, Magnolia, Yew, Euonymus, fruit trees and numerous conifers such as Hemlock. You may see black, sooty residue on leaves, white specks, cottony masses, and wart-like bumps on stems, twigs or branches. Conversely, you may not notice there’s an issue until the tree or shrub becomes discolored, starts to die back, or loses leaves or pine needles. If you see any of these signs of scale, schedule an inspection with a Giroud ISA Certified Arborist as soon as possible because catching it early is key!


These annoying insects are inevitable in summer, but they don’t have to ruin your backyard fun! Diseases and illnesses like Zika and West Nile Virus can be transmitted by mosquitoes, so it’s important to protect yourself and your loved ones. The CDC (Centers for Disease Control) has reported that illnesses and diseases from these pesky insects have tripled in the United States in the last decade! 

Keeping your yard clean, removing standing water, pruning your trees to let sun down on shady spots are all great ways to keep mosquitoes off your property. However, oftentimes a stronger approach is needed. Giroud offers both Traditional and Organic Mosquito control! You can enjoy your yard all summer long without worrying about pesky biting bugs!


Ticks carry a frightening array of horrible illnesses and diseases that can affect your family and your pets! We often think that ticks can only be found in wooded areas, but you’d be amazed at how many could be living in your own yard. The good news is that there’s so much you can do to keep ticks away from your property.

Just like mosquitoes, ticks love hiding in shady spots. Pruning back tree branches and cleaning up underbrush make your yard less desirable to terrible ticks. Giroud offers a variety of tick control programs, from Traditional sprays to Organic treatments. Our Deer Control Program will keep the animals that carry ticks off your property as well!

Spotted LanternflySpotted Lanternfly

By far, the most concerning insect this year is the Spotted Lanternfly. SLF invaded Pennsylvania back in 2014, and they have reproduced in concerning numbers since then. This year is expected to be the worst yet, and many homeowners are already seeing Spotted Lanternfly Nymphs all over their properties! In just a short few weeks, they will turn into adults, and it’s during that stage that they cause the most trouble.

Spotted Lanternfly feed on trees and plants, causing damage and stress to them. The insect also excretes a substance called “honeydew” as they feed, and this sticky, sweet stuff attracts stinging wasps to your property!

Giroud offers Spotted Lanternfly Control, but the schedule is already full for July. You need to act now if you see signs of the insect on your property because our August schedule is filling up fast!
