What Does the Cicada Look Like? A Homeowner’s Guide to Identification & Control

Imagine a warm summer afternoon when a sudden, rhythmic buzz fills your backyard. You look up and spot a large, almost translucent insect clinging to a tree branch, its wings shimmering in the sun. For many homeowners, that moment sparks curiosity—and sometimes a little concern. Knowing what does the cicada look like can turn a puzzling encounter into an opportunity to manage these noisy neighbors responsibly.

While cicadas are not typically classified as household pests, their massive emergences can create unexpected challenges. Their loud calls, sudden swarms, and occasional accidental entry into homes make it worthwhile for any homeowner to recognize them, understand why they show up, and learn safe, effective ways to coexist or control them when necessary.

What Does the Cicada Look Like? Identifying This Summer Visitor

The first step in dealing with any insect is proper identification. When you ask yourself “what does the cicada look like?” focus on several key characteristics that set cicadas apart from other bugs you might encounter around the house.

What Does the Cicada Look Like? Key Physical Features

• Size: Adult cicadas range from 1 – 2 inches (25‑50 mm) in body length, though some tropical species can exceed 4 inches.
• Body Shape: They have a stout, somewhat oval thorax and a tapered abdomen that may appear black, brown, or greenish.
• Eyes: Large, compound eyes dominate the head, often a bright reddish‑brown color.
• Wings: Two pairs of clear or veiny wings that extend well beyond the abdomen; the forewings are more robust, while the hindwings are slightly shorter.
• Sound‑producing Organs: Males possess tymbals—ribbed membranes on the abdomen—that they vibrate to create the characteristic buzzing.
• Coloration: Many species display muted greens or browns with faint patterns, perfect camouflage among leaves. Some periodical cicadas have black bodies with orange‑red wing veins.

Understanding what does the cicada look like helps you differentiate them from harmless grasshoppers, beetles, or the more troublesome stink bugs that might also be present in your garden.

Why Cicadas Appear Near Homes

Cicadas spend most of their lives underground as nymphs, feeding on tree root sap. When the soil temperature reaches about 64 °F (18 °C), they emerge en masse, seeking mates and laying eggs on thin branches. This natural cycle explains why you often see them clustered on ornamental trees, shrubs, and even fence posts surrounding a house.

Factors that draw cicadas closer to human dwellings include:

• Abundant Food Sources: Deciduous trees like oak, maple, and birch provide the sap cicada nymphs need.
• Moisture: Damp soil speeds up nymph development, leading to larger emergences after a rainy spring.
• Entry Points: Gaps around windows, doors, and vent screens allow adult cicadas to wander indoors while searching for shade.
• Urban Heat Islands: Cities retain heat, sometimes prompting earlier or more frequent emergences.

Signs of Cicada Activity in Your Property

Even if you haven’t heard the loud chorus yet, there are subtle clues that cicadas are around:

• Shedded exoskeletons (exuviae) stuck to tree bark or garden furniture.
• Clusters of dead or dying branches where females have inserted eggs.
• Fine, white waxy secretions on leaves—cicada nymphs produce this when they crawl out of the ground.
• Unusual buzzing that intensifies around dusk.

Spotting these signs early can help you decide whether simple preventive steps are enough or if you need a more active approach.

Safe and Natural Management Methods

Before reaching for chemicals, many homeowners prefer non‑toxic solutions. Here are three practical methods that work for most suburban settings.

1. Physical Barriers

Install fine‑mesh screens on windows, vents, and doorways. The mesh size should be no larger than 1 mm to keep adult cicadas out while still allowing airflow.

2. Pruning and Removal

Trim lower branches of trees near the house. This reduces landing spots and makes it harder for cicadas to reach windows or eaves.

3. Light Management

Adult cicadas are attracted to bright lights at night. Switching to amber or sodium‑vapor bulbs can lessen nighttime draws. Turning off unnecessary exterior lighting during peak cicada season (late summer) also helps.

These natural methods align with the principle of integrated pest management—use the least invasive tactics first, and only move to stronger measures if needed.

Chemical and Product Options for Cicada Control

If an infestation becomes overwhelming—say, thousands of cicadas filling a porch or repeatedly entering a sunroom—targeted chemical treatments may be warranted. Keep the following in mind:

• Active Ingredients: Pyrethroids (e.g., permethrin) are commonly used for outdoor surface sprays. They knock down adult cicadas quickly but have limited residual activity.
• Application Timing: Apply in the early morning or late evening when cicadas are less active to minimize exposure to non‑target insects like pollinators.
• Safety: Follow label directions, wear protective gloves, and keep children and pets away from treated areas for at least 24 hours.
• Common Mistake: Over‑spraying foliage can harm beneficial insects. Use a spot‑spray approach on branches where cicadas are congregating.

For homeowners uncomfortable handling chemicals, consider hiring a licensed professional who can apply low‑impact treatments safely.

Common Mistakes Homeowners Make

Even well‑meaning attempts can backfire. Here are pitfalls to avoid:

• Ignoring Exuviae: Those shed skins signal a pending emergence. Removing them doesn’t stop cicadas, but it helps you gauge timing.
• Using Broad‑Spectrum Insecticides Indoors: This can harm indoor pollinators and create health risks for family members.
• Leaving Food Sources Unmanaged: Fruit trees or over‑ripe fruit on the ground attract adult cicadas looking for sugar.
• Over‑pruning: Removing too many branches can stress trees, making them more vulnerable to other pests.

Prevention and Long‑Term Control

Preventing future nuisances is often cheaper and easier than reacting after the fact. Use this checklist each spring:

• Inspect and repair screen meshes around windows and vents.
• Trim lower limbs of trees within 10 feet of the house.
• Remove fallen fruit and clean up leaf litter to reduce food sources.
• Apply a light‑reflective film on exterior glass to discourage landing.
• Consider planting cicada‑deterrent species (e.g., evergreens) near entryways.

When to Call a Professional

Most cicada encounters are harmless, but consider professional help if you notice any of the following:

• Large swarms entering living spaces despite barriers.
• Damage to young trees from egg‑laying females (tiny slits in branches).
• Allergic reactions to cicada exoskeleton fragments or saliva.
• Repeated cycles of emergence that overwhelm your DIY methods.

A licensed pest‑control technician can assess your property, recommend low‑impact treatments, and ensure compliance with local regulations.

Frequently Asked Questions

Do cicadas bite or sting?

No. Adult cicadas lack stingers and do not bite. Their mouthparts are designed for feeding on plant sap, not for defense.

How long does a cicada’s life cycle last?

Most cicadas spend 2‑5 years as underground nymphs, while periodical species (e.g., 13‑year or 17‑year cicadas) remain underground for that exact number of years before emerging.

Can cicada droppings damage my house?

Fecal pellets are tiny and generally harmless. However, heavy concentrations on windowsills or decks can create a mess that requires cleaning.

Is it safe to use household insect spray on cicadas?

Standard indoor sprays may work temporarily but are not designed for large outdoor swarms and can pose health risks. Opt for outdoor‑labelled products or professional services.

Are cicadas beneficial?

Yes. They aerate soil during emergence, provide a massive food source for birds and mammals, and their decaying bodies enrich the ecosystem.

Understanding what does the cicada look like gives you the confidence to manage their presence intelligently. By combining accurate identification, preventive landscaping, and the right mix of non‑chemical and, when necessary, chemical controls, you can enjoy a quiet summer evening without the constant buzz.
