In many cases, noisy insects are seasonal, temporary, and more annoying than destructive. The smart approach is to identify what you are hearing, check whether there is real plant damage or home entry, then decide whether to tolerate it, protect vulnerable plants, seal the house, or call a licensed pest-control professional.
The four noisy insects homeowners most often notice around lawns, gardens, trees, porches, and foundation plantings are cicadas, crickets, katydids, and grasshoppers. They are loud mostly because males are calling for mates. That sound can be startling, especially near trees or at night with the windows open, but the control plan should be based on damage, not noise alone.
On our job sites, the insect problems that turn into construction problems are usually tied to conditions around the house: damp foundation edges, deep mulch against siding, failing door sweeps, loose garage seals, open utility penetrations, crawl-space humidity, or deteriorated exterior wood. A spray may quiet a symptom for a short period, but the durable fix is often better drainage, better sealing, and better exterior maintenance.
Quick Comparison: Which Noisy Insect Are You Hearing?
Use timing, location, and visible damage to narrow the culprit. You do not need a microscope for the first decision. Walk the yard at the time you hear the sound, look at the plants closest to the noise, and check the house perimeter for entry points.

#1 Best Overall
| Insect | Typical Sound Timing | Where You Notice It | Main Concern | Best First Response |
|---|---|---|---|---|
| Cicadas | Daytime, especially hot afternoons | Mature trees, wooded edges, large shrubs | Egg-laying cuts in small twigs on young trees | Net young trees with 1/4-inch or smaller mesh |
| Crickets | Evening and night | Foundation edges, garages, basements, porch lights | Indoor entry, fabric damage, nuisance noise | Reduce lighting, dry the foundation zone, seal gaps |
| Katydids | Dusk and night | Trees, shrubs, tall vegetation | Usually minor leaf chewing | Monitor prized plants; tolerate unless damage rises |
| Grasshoppers | Daytime clicks, buzzing, and visible movement | Gardens, weedy borders, lawns, fields | Leaf chewing on vegetables and ornamentals | Monitor early nymphs, use row covers, treat only when needed |
A practical threshold helps. If the insect is noisy but plants are healthy and nothing is entering the house, control may not be worth the cost. If young trees, vegetable beds, or indoor living areas are affected, act early with targeted measures.
1. Cicadas: Loud, Seasonal, and Usually Not Worth Spraying
Cicadas are the loudest insect on this list. Dense choruses near trees can commonly reach the 90 to 110 decibel range close to the source, and sound levels may still be around 80 to 85 decibels from 12 to 24 feet away. For homeowners with sound sensitivity, the practical answer may be distance, closed windows, and hearing protection during prolonged yard work near active trees.
The key point: cicada damage is not mainly from feeding. The concern is egg-laying. Female cicadas cut small slits into twigs and branches, especially on young ornamental trees, fruit trees, and newly planted shrubs. The affected twig ends can brown, break, or flag. Large established trees usually tolerate this without meaningful long-term harm.
What to do for cicadas
Protect young trees and skip broad spraying. For newly planted or small high-value trees, wrap the canopy with fine mesh, tulle, or insect netting with openings of 1/4 inch or smaller. Secure it around the trunk so cicadas cannot crawl underneath. Expect to spend roughly $15 to $60 per tree depending on tree size and material quality.
Do not wrap netting tight against new growth. Leave enough space for leaves and branch tips, then check ties after storms. Remove the netting when the local cicada activity has passed so the tree gets normal airflow and sunlight.
For established shade trees, the best plan is usually tolerance and cleanup. After the emergence, prune dead or broken twig tips with clean cuts. Avoid heavy pruning during the event unless a limb is already unsafe. If a tree overhangs a roof, deck, driveway, or walkway and you see cracked limbs, bring in an arborist rather than trying to manage ladder work from uneven soil.
Should you spray for cicadas?
Usually, no. Pesticides are generally ineffective for keeping cicadas away, and blanket treatment of large trees is rarely justified for a residential yard. Spend the budget on protecting young trees, pruning after the event, and correcting any unrelated tree hazards.
2. Crickets: Night Noise Plus Home Entry Problems
Crickets are a different problem because they often move from the yard into the house. They like bright exterior lighting, damp areas, tall grass, wood piles, clutter, and small gaps around foundations, doors, windows, garage seals, vents, and utility penetrations. Once inside, house and field crickets may damage fabrics such as cotton, linen, wool, silk, and fur, especially when the material has perspiration or food residue.
Recommended Free Tools
In the field, cricket work often looks like basic exterior maintenance. We look for the same conditions that cause rot, mold, and nuisance pests: water against the foundation, vegetation touching siding, loose thresholds, torn vent screens, and old sealant around pipes or cables.
Rank #2
Cricket control that actually holds
Start outside. Replace bright white porch and security bulbs with yellow or amber bulbs where practical. Typical bulbs cost about $5 to $25 each. Keep grass trimmed near the foundation, move firewood and stored materials at least 20 feet from the house when the lot allows, and keep mulch a few inches below siding and trim.
Next, seal the openings. Door sweeps and weatherstripping commonly cost $10 to $40 per opening for materials. Exterior caulk or foam often runs $5 to $20 per product. Focus on garage door corners, basement windows, crawl-space vents, utility penetrations, gaps under thresholds, and torn screens. A gap only 1/4 inch high is enough for many crawling insects to exploit.
Then dry the edge of the house. Downspouts should discharge away from the foundation, not into the mulch bed. Soil should slope away from the wall where possible. If the crawl space smells damp or insulation is sagging, pest control alone is not the answer. Moisture correction may involve drainage improvements, vapor barrier work, vent repair, dehumidification, or wood replacement.
3. Katydids: Loud at Night, Usually Minor in the Landscape
Katydids are often blamed for a backyard that feels loud after sunset. Their calls can carry through trees and shrubs, and they can be persistent on warm nights. In most healthy residential landscapes, though, katydids are more of a noise issue than a serious pest issue.
They chew foliage, but the damage is usually scattered. A few ragged leaves on a mature shrub do not justify a treatment program. The exception is a prized ornamental, a small newly planted shrub, or a garden bed where chewing is increasing and you can confirm katydids are the source.
How to handle katydids
Use monitoring first. Inspect the damaged plant in the evening with a flashlight and look at both sides of the leaves. If damage is light, tolerate it. If damage is concentrated on a small plant, hand removal, temporary netting, or pruning back dense surrounding vegetation may be enough.
Avoid treating for sound alone. Yard-wide spraying for katydids can disrupt beneficial insects and still may not give the homeowner the quiet result they expect. If the problem is mostly sleep disruption, practical steps such as closing windows on the affected side of the house, reducing vegetation directly against bedroom walls, and improving window seals may do more than pesticide.
4. Grasshoppers: The Noisy Insect Most Likely to Eat the Garden
Grasshoppers are the most plant-damaging insect in this group. Not every species causes serious damage, but outbreaks can affect gardens, crops, lawns, and nearby weedy areas. The visible signs are chewed leaf edges, stripped seedlings, and grasshoppers jumping as you walk through the bed.
The timing matters. Early nymphs are easier to manage than large adults. Once adult grasshoppers are mobile, they can move in from adjoining lots, fields, ditch lines, and unmowed edges. That is why a garden can look fine one week and ragged the next.
Grasshopper control steps
Start monitoring early in the season. Check weedy borders, fence lines, and sunny dry areas where young grasshoppers may develop. Reduce unnecessary weeds and unmanaged grass near vegetable beds where practical, but do not disturb slopes or drainage areas in a way that creates erosion.
Use physical protection for high-value plants. Floating row cover commonly costs $15 to $50 per roll and works well for seedlings and leafy crops if installed before heavy feeding begins. Anchor edges with soil, staples, boards, or landscape pins so insects cannot enter underneath. Remove or open covers when crops need pollination.

Costs: What Homeowners Should Expect in 2026
For noisy garden insects, the cheapest effective fix is often not a general spray. Cicadas may need $15 to $60 of netting per young tree. Crickets may need $10 to $40 door sweeps, $5 to $20 sealant, and a few lighting changes. Grasshoppers may need row cover or, in heavier pressure, a targeted pest-control visit.
| Service or Material | Typical 2026 US Cost | Best Use |
|---|---|---|
| One-time general pest-control visit | About $100 to $600; many common visits fall around $100 to $300 | Cricket entry, targeted outdoor nuisance treatment, inspection |
| Typical exterminator visit range | About $131 to $341, with a typical cost near $209 | Common residential pest issues where identification is needed |
| Monthly pest service | About $40 to $75 per visit | Recurring pressure around the home, not usually needed for cicadas alone |
| Annual pest plan | About $300 to $900 | Homes with repeated seasonal pest issues |
| Lawn insect treatment | Roughly $0.34 to $0.44 per square foot before local adjustments | Large lawn or turf insect problems, not a default for noisy insects |
| Young-tree insect netting | About $15 to $60 per tree | Cicada protection for young fruit, ornamental, or newly planted trees |
| Door sweep or weatherstripping | About $10 to $40 per opening | Cricket exclusion, drafts, dust, and water control |
| Exterior caulk or foam | About $5 to $20 per product | Utility gaps, trim joints, foundation penetrations |
| Floating row cover | About $15 to $50 per roll | Grasshopper protection for seedlings and vegetables |
Cost varies by property size, number of treatment zones, pest species, severity, whether insects are outdoors only or entering the home, product restrictions around edible gardens, ladder or tree access, local labor rates, and whether repair work is included. A small cricket exclusion job may be less expensive than a repeat treatment plan. A large grasshopper outbreak affecting multiple beds may cost more than a simple indoor pest visit.
Exterior Maintenance That Reduces Noisy Pest Pressure
This is where a construction mindset helps. Insects respond to habitat. The tighter, drier, and cleaner the home perimeter is, the fewer places noisy pests have to gather, hide, or enter.
Lighting
Bright white lighting attracts many nighttime insects and can pull activity toward porches, doors, and windows. Use warmer yellow or amber bulbs where security needs allow. Aim fixtures downward and avoid lighting dense shrubs directly against the house. Motion fixtures can also reduce the number of hours insects are drawn to one spot.
Drainage and moisture
Keep gutters clear and downspouts discharging away from the foundation. Correct low spots that hold water beside the house. Damp mulch, wet crawl spaces, and shaded foundation corners create conditions that crickets and other pests favor. If water repeatedly returns after grading or downspout changes, the issue may need a drainage contractor.
Mulch and vegetation clearance
Keep mulch below siding and trim, not piled against wood. Maintain visible clearance at the foundation so you can inspect for gaps, rot, and insect activity. Trim shrubs and vines back from siding, windows, vents, and deck framing. Dense vegetation touching the house gives insects cover and makes exterior defects harder to see.
Seals and openings
Check door sweeps, garage seals, window screens, crawl-space vents, and utility penetrations twice a year. Spring and fall are good times because seasonal movement opens small gaps. Replace brittle rubber, torn screens, and failed caulk. These small repairs also help with drafts, dust, and water intrusion.

Decks, porches, and exterior wood
Noisy insects do not usually damage structural wood the way termites or carpenter ants can, but the conditions that attract pests often overlap with the conditions that damage decks and porches. Look for soft boards, loose rail posts, rusted connectors, failing stair stringers, and wood that stays wet. If a deck, balcony, or porch feels springy, slopes unexpectedly, or has loose guards or rails, treat it as a safety issue, not a pest issue.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When to DIY and When to Hire a Pro
DIY is reasonable when the issue is seasonal noise, light plant chewing, or obvious small repairs. Netting a young tree, adding row cover, changing bulbs, trimming grass, moving wood piles, and replacing a door sweep are all within reach for many homeowners. Keep the work neat and measurable: mesh openings 1/4 inch or smaller for cicadas, mulch below siding, vegetation pulled back from walls, and gaps sealed at doors and utility penetrations.
Hire a licensed pest-control pro when insects are entering living areas repeatedly, grasshopper damage is accelerating across multiple beds, you cannot identify the pest, or treatment near edible gardens requires product knowledge. Ask for the insect identification, treatment zones, product names, label rates, re-entry guidance, and whether follow-up visits are included.
Hire a contractor when the pest issue points to a building problem: recurring moisture near the foundation, damaged exterior wood, failing deck boards or rails, gaps around doors and windows, crawl-space humidity, damaged vents, or repairs that affect structure, stairs, guards, landings, or exterior wall assemblies. Many exterior repairs are simple, but structural deck and porch work may require permits depending on the city or county. Permit rules vary, so verify locally before replacing load-bearing members, expanding a porch, changing stairs, or rebuilding guards and rails.

Start with identification. Is the sound mostly daytime from trees? Think cicadas. Evening or night near the foundation? Look for crickets. Dusk and night from shrubs and trees with little damage? Katydids are likely. Daytime jumping insects with chewed leaves? Check for grasshoppers.
Next, inspect damage. Look at young trees for twig slits and flagging, vegetable beds for fresh chewing, and the house perimeter for droppings, insects, gaps, and damp areas. If there is no meaningful damage and nothing is entering the house, tolerance may be the correct professional recommendation.
Then choose the least-disruptive control. Protect high-value plants with netting or row cover. Correct habitat by reducing weeds, moisture, clutter, and bright lighting. Exclude pests with door sweeps, screens, caulk, and foam. Use pesticides only for targeted situations where the label allows that use.
Finally, reassess. A good pest plan is not one spray and a guess. Check the same plants and openings 3 to 7 days later, then again after the next heavy rain or warm spell. If the problem is improving, keep going. If damage spreads or insects keep entering the house, it is time for professional identification and a more complete repair or treatment plan.

Bottom Line
Noisy garden insects are not all the same. Cicadas can be extremely loud but usually need tree protection, not spraying. Crickets call for exclusion, lighting changes, and moisture control. Katydids are usually tolerable unless prized plants show real damage. Grasshoppers deserve the closest attention because they can strip garden plants quickly when populations rise.
The best homeowner strategy is simple: identify the insect, inspect for actual damage, protect the plants that matter, tighten the home exterior, and spend professional money only where it solves the underlying problem. That approach keeps the yard healthier, the house tighter, and the repair budget focused on work that lasts.
Frequently Asked Questions
What insects make loud noises in the yard at night?
Crickets and katydids are the most common nighttime noisemakers. Crickets are often near foundations, garages, porch lights, and damp areas. Katydids usually call from trees, shrubs, and taller vegetation.
Are cicadas harmful to trees or just noisy?
Cicadas are mostly a noise issue for established trees. The real risk is to young or newly planted trees, where females can cut small twigs to lay eggs. Protect vulnerable trees with 1/4-inch or smaller mesh during heavy activity.
Should I spray for cicadas in my yard?
Usually no. Spraying is generally not an effective default for cicadas. Net young trees, tolerate activity on large established trees, and prune damaged twig tips after the emergence passes.
How do I keep crickets from getting into my house?
Reduce bright exterior lighting, dry the foundation zone, trim grass, move wood and clutter away from walls, and seal gaps at doors, windows, garage seals, vents, and utility penetrations. Door sweeps often cost $10 to $40 per opening.
Do katydids damage garden plants?
Katydids chew leaves, but they rarely cause enough damage in a healthy residential landscape to justify treatment. Monitor prized plants and use hand removal or temporary netting if chewing becomes concentrated.
How much does outdoor insect control cost in 2026?
A one-time pest-control visit commonly runs about $100 to $600, with many standard visits around $100 to $300. DIY materials such as netting, row cover, amber bulbs, caulk, and door sweeps often solve smaller problems for less.
