The best fly trap depends on which fly you’re fighting and where. House flies breeding around trash cans and pet waste outside call for a scented bait trap hung well away from the patio. Fruit flies circling the fruit bowl want a small vinegar-style lure on the counter. Fungus gnats rising from houseplants and stray flies that drift in through a door are better handled by a plug-in light trap or a strip of fly paper. One product rarely does all of it. Below are seven picks matched to those jobs, followed by a buying guide on placement, safety around kids and pets, the sanitation steps that matter more than any trap, and when a sudden indoor fly swarm is a sign of something in the walls or attic.

As an Amazon Associate we earn from qualifying purchases.

How we compared: we compared 15 current Amazon listings for fly traps on what each listing states: how the trap attracts flies (light, food lure, scent bait or color), which flies it targets, indoor or outdoor use, how long a refill or lure lasts, and any placement warnings. We did not lab-test these traps or use them hands-on. Several listings are pack-size variants of the same trap, which we count once when comparing designs. Prices and availability change often, so check the current listing before buying.

The 7 picks, compared listing by listing

1. Zevo Flying Insect Trap (1 Base + 3 Cartridges) — Best for Indoor Flies, Fruit Flies and Gnats

Best indoor trapZevo Flying Insect Trap

Plug-in trap using blue and UV light with a hidden adhesive cartridge for house flies, fruit flies and gnats indoors.

Check price on Amazon$25.96 as of Oct 21, 2026 8:21 am GMT+0000 — prices change; see Amazon for current price.

Why we like it

  • Catches flies around the clock with light
  • Adhesive faces the wall, hiding catches
  • No spray, zapping or odor
  • Blinking reminder to swap cartridges
  • Three cartridges included to start
Specification Details
Attractant Blue and UV light
Capture Disposable adhesive cartridge, wall-facing pad
Targets House flies, fruit flies, gnats and other small flying insects
Power Plugs into a wall outlet
Cartridge interval Light blinks to prompt a check every six weeks
In the box 1 device, 3 cartridges (Model 4)

Zevo Flying Insect Trap — plug-in blue/UV light, wall-facing glue cartridge, 6-week reminder, 1 base + 3 refills

The Only Plug-In Trap With a Cartridge Reminder

Four of the 15 listings are plug-in light traps: three Zevo pack sizes and Safer’s SH502. Zevo is the only one whose listing describes a reminder, a blinking light that prompts a cartridge check every six weeks. That sounds minor, but a glue trap full of insects stops catching, and a hidden cartridge is easy to forget.

The hidden cartridge is the other draw. The adhesive pad faces the wall, so catches aren’t on display on a kitchen counter, and the listing says the trap works without spraying, zapping or added odor. Zevo also names a wider set of targets than Safer, listing house flies alongside fruit flies and gnats, and gives clear placement advice: near fruit bowls, trash bins and houseplants, where small flies gather.

The listing doesn’t state a coverage area or catch rate, and a light trap in a sunny kitchen competes with daylight. This three-cartridge pack is the best value of the three Zevo listings for a first purchase, since cartridges are the ongoing cost.

Pros

  • Continuous light attraction, no chemicals
  • Catches hidden from view
  • Six-week cartridge reminder
  • Wide target list

Cons

  • Needs an outlet near the problem
  • Ongoing cartridge cost
  • Coverage not stated

2. RESCUE! Outdoor Disposable Fly Trap (2 Traps) — Best for Outdoor House Flies

Best outdoor trapRESCUE! Disposable Fly Trap

Hanging bag trap with water-activated scent bait for trash areas, kennels and yards; hang 20+ feet from living areas.

Check price on Amazon$11.92 as of Oct 21, 2026 8:21 am GMT+0000 — prices change; see Amazon for current price.

Why we like it

  • Scent bait pulls flies away from patios
  • Just add water and hang
  • Disposable: no handling dead flies
  • States EPA registration and U.S. manufacture
Specification Details
Attractant Water-activated scent bait
Capture Disposable hanging bag; discard when full
Where to use Outdoors: garbage cans, kennels, barns, backyards
Placement At least 20 feet from living spaces (strong odor)
Registration Listing says EPA registered (number not given)
Pack 2 traps (an 8-trap pack is also listed)

RESCUE! Disposable Fly Trap — water-activated bait bag, outdoor only, hang 20+ ft from living areas, 2 traps

The Only Trap on the Shelf That Says It’s EPA Registered

Four listings are outdoor bait-and-water traps: RESCUE!’s disposable bag in 2- and 8-packs, RESCUE!’s reusable trap and TERRO’s T380. The disposable RESCUE! listings are the only ones among all 15 that say the product is EPA registered. That matters because the bait in an outdoor fly trap is the active part, and a registration means the EPA has reviewed it for use as directed.

The bag design suits the job most homeowners face: house flies around trash and dog runs in summer. You add water, hang it and throw the whole thing away when full, with no rinsing a trap full of drowned flies. All three RESCUE! listings warn that the activated bait smells strong and should hang at least 20 feet from living areas. Put it near the source, such as the trash enclosure or the far side of the yard, not next to the patio table.

The listing doesn’t state how long a bag lasts or how many flies it holds. Strong Front Range afternoon winds can twist and swing a hanging bag, so tie it to a fence post or tree limb out of the gusts.

Pros

  • EPA registration stated
  • Simple add-water setup
  • Disposable, no cleanup
  • Targets common nuisance flies outdoors

Cons

  • Strong odor; must hang 20+ ft away
  • Outdoor use only
  • Lifespan per bag not stated

3. TERRO T380 Fly Magnet Reusable Trap — Best Reusable Outdoor Trap

Why we like it

  • Empty, refill and reuse each season
  • Bait included; replacement bait sold
  • Non-poisonous bait, per listing
  • Names house, barn and bottle flies
Specification Details
Attractant Non-poisonous food bait plus trap color and lid shape

Where to use Outdoors: patios, decks
Refills Replacement bait sold as #M381
Placement distance Not stated in listing

TERRO T380 Fly Magnet — reusable 1-quart outdoor trap, non-poisonous bait, refill bait #M381

A Reusable Trap That Names the Flies It Targets

Two listings are reusable outdoor traps: this TERRO and RESCUE!’s reusable model. Both work the same way. Flies follow the bait scent inside and drown in the water. The TERRO listing stands out for naming specific targets (house flies, barn flies and bottle flies), describing a diamond-shaped lid and color designed to draw flies, and giving a replacement bait part number so you can keep the trap running.

A reusable trap costs more up front and makes sense for a property with a season-long fly problem, such as a home with dogs, chickens or a compost pile. The trade-off is maintenance. You’ll be emptying a container of decomposing flies and bait, and you need to keep adding water so the catch stays submerged, as the listing directs.

Unlike the RESCUE! listings, TERRO doesn’t state a placement distance. Bait traps smell by design, so hang it well away from doors and seating anyway.

Pros

  • Reusable season after season
  • Non-poisonous bait, per listing
  • Named target flies and refill part number

Cons

  • Messy to empty
  • Needs water topped up
  • No placement distance given

4. TERRO Fruit Fly Trap 4-Pack — Best for Fruit Flies on the Counter

Best fruit fly trapTERRO Fruit Fly Trap 4-Pack

Four apple-shaped traps with a food-based liquid lure, each lasting up to 45 days, for a 180-day supply.

Check price on Amazon$12.19 as of Oct 21, 2026 8:21 am GMT+0000 — prices change; see Amazon for current price.

Why we like it

  • Purpose-built for fruit flies
  • Up to 45 days per trap
  • Window shows catches and lure level
  • Blends in on a fruit bowl
Specification Details
Attractant Food-based liquid lure
Targets Fruit flies
Lure life Up to 45 days per trap; 180 days for the 4-pack
Where to use Fruit bowls, trash cans, kitchen counters
Size About 2.25 in wide, apple-shaped
Model T2503SR

TERRO Fruit Fly Trap — 4 apple-shaped traps, food-based lure, 45 days each / 180 days total, monitoring window

The Only Dedicated Fruit Fly Trap on the Shelf

Several listings mention fruit flies, but this is the only one built exclusively for them, and the only one that states a lure life per trap: up to 45 days. The plug-in traps catch fruit flies with light and glue; this trap uses a food lure, which is how fruit flies find what they’re looking for in the first place.

The design details are practical. A monitoring window shows both the catch and the remaining lure, so you know when to replace a trap rather than guessing. The apple shape sits on a fruit bowl without looking out of place, and at about two inches across it fits next to a sink or a compost caddy.

It won’t do much for house flies, and the listing doesn’t claim it will. Fruit flies breed in overripe produce, drains and recycling, so a trap thins the adults while cleanup removes the source.

Pros

  • Targets fruit flies specifically
  • 45-day lure life stated
  • Window shows lure level

Cons

  • Fruit flies only
  • Small capacity per trap
  • Doesn’t address breeding sites

5. TERRO T518 Fly Magnet Sticky Strips — Best for Garages and Porches

Why we like it

  • No bait, no odor, no power
  • Eight ribbons for multiple spots
  • Disposable once full
  • Lowest-effort option on the shelf
Specification Details
Attractant None; sticky ribbon only
Capture Hanging adhesive ribbon
Count 8 fly papers
Where to use Indoors, hung from ceilings or fixtures
Lifespan Not stated in listing

TERRO T518 Fly Magnet — 8 hanging sticky ribbons, no bait or odor, disposable, lifespan not stated

Classic Fly Paper From a Name-Brand Maker

Five of the 15 listings are passive sticky traps: TERRO’s T518, BugBane’s 24-strip pack and its four- and six-pack fly sticks, and LFSYS’s window traps. Fly paper catches whatever lands on it, so it works on house flies in a garage, mudroom or barn where looks don’t matter and there’s no outlet for a plug-in trap.

The TERRO listing is short. It promises no bait, no odor and no mess, a ribbon design and eight papers per pack. BugBane’s 24-pack says its strips can last up to three months outdoors; TERRO gives no lifespan. TERRO is the better choice if you only need a few strips, and BugBane if you want to cover a barn or several outbuildings.

Fly paper has trade-offs. It catches whatever lands on it, including beneficial insects when hung outdoors, and it’s sticky enough to tangle in hair or pet fur. Hang ribbons above head height and out of reach of children and pets, not in a doorway where someone will walk into one.

Pros

  • No power, bait or odor
  • Eight ribbons per pack
  • Works anywhere flies land

Cons

  • Unsightly in living spaces
  • Catches non-target insects
  • Lifespan not stated

6. Hot Shot Flying Insect Trap (6 Count) — Best When There’s No Outlet

Best no-plug indoor trapHot Shot Flying Insect Trap

Six compact traps for house flies and fruit flies with no plug or electricity; not for fungus gnats or drain flies.

Check price on Amazon$16.49 as of Oct 21, 2026 8:21 am GMT+0000 — prices change; see Amazon for current price.

Why we like it

  • No outlet or batteries required
  • Catches house flies and fruit flies
  • Discreet design for kitchens
  • Honest about what it won’t catch
Specification Details
Attractant Continuous attraction; method not detailed in listing
Targets House flies and fruit flies
Not intended for Fungus gnats, drain flies
Power None; no plug-in or electricity
Count 6 traps

Hot Shot Flying Insect Trap — 6 no-power traps, house + fruit flies, not for fungus gnats or drain flies

The Only Indoor Trap That Says What It Won’t Catch

Hot Shot’s trap covers ground between a fruit fly lure and a plug-in light trap: it targets house flies and fruit flies indoors without needing an outlet. That suits kitchen islands, pantries and bathrooms where the nearest outlet is in the wrong place.

Its listing is also the only one among the 15 that states what the trap is not for: fungus gnats and drain flies. That’s useful information. Gnats rising from houseplants and moth flies coming out of a slow drain are two of the most common indoor small-fly complaints, and a buyer would otherwise assume any “flying insect trap” handles them. For those, a light trap such as Zevo, which names gnats and houseplants, fits better.

The listing doesn’t say how the trap attracts flies or how long each one lasts, so plan to replace them when they look full.

Pros

  • No electricity needed
  • Six traps per pack
  • States its limits clearly

Cons

  • Not for gnats or drain flies
  • Lifespan not stated
  • Attraction method not described

7. LFSYS Window Fly Traps (50 Pack) — Best for Flies Stuck at Windows

Best window trapLFSYS Window Fly Traps

  • No residue on glass, per listing
  • No bait, power or odor

LFSYS Window Fly Traps — 50 clear sticky window panels, ~8.6 x 3.2 in, indoor, no-residue claim

The Only Trap Designed for the Window Itself

Flies that get inside head for the light, which is why they bump along the glass of a sunny window for hours. LFSYS’s clear panels are the only window-specific trap among the 15 listings. They stick to the pane where flies already are, so they catch without any lure.

Fifty traps is by far the highest count on the shelf, which suits a house with many windows or a seasonal problem that recurs every fall. The listing claims the traps leave no sticky residue on glass and are invisible to flies, though we’d treat the second claim as marketing.

The trade-off is that a window trap only catches flies already inside and drawn to the light. It does nothing about the source. A cluster of flies on the same window each day is worth investigating, as the buying guide explains.

Pros

  • Highest trap count on the shelf
  • Catches flies where they gather
  • Clear panels, no residue claimed

Cons

  • Only catches flies already inside
  • Visible catches on the glass
  • Marketing claims are broad

Matching the trap to the fly

Identifying the fly saves money. Here is how the trap types on this shelf line up with the most common household complaints:

  • House flies outdoors (trash, pet waste, compost): scent-bait traps such as RESCUE! and TERRO T380, hung near the source and well away from doors.
  • House flies indoors: plug-in light traps, no-plug traps like Hot Shot, fly paper in garages and window traps where flies gather.
  • Fruit flies: food-lure traps like TERRO’s apple traps on the counter, plus plug-in light traps.
  • Fungus gnats: light-and-glue traps near houseplants. Gnats breed in damp potting soil, so letting the top of the soil dry between waterings matters more than the trap. A plant moisture meter takes the guesswork out of watering.
  • Drain flies: no trap here claims them, and Hot Shot excludes them. Clean the drain and its overflow, and check for a slow or broken drain line.

Bug zappers are a different tool, used mostly outdoors at night; our bug zapper roundup compares them. For biting insects in the yard, see our guide to mosquito repellent for the yard.

Sanitation first: what the EPA recommends before any trap

Traps catch adults, but flies keep coming as long as they have somewhere to breed. The EPA’s advice on whether you really need a pesticide applies directly. Keep a tight lid on trash and empty it often, place trash cans away from the back door, clean up spills and leftovers right away, don’t leave pet food out overnight and repair holes in door and window screens.

The EPA’s integrated pest management principles take the same approach. Monitor and identify the pest, prevent access first, and choose less risky controls such as trapping before turning to targeted sprays. Broadcast spraying of non-specific pesticides is a last resort. A trap is a good fit for that hierarchy. It’s a monitoring tool as much as a control, because a trap that fills fast tells you the source is close.

On the Front Range, outdoor fly pressure peaks in the warm months, and afternoon wind makes hanging traps swing. Anchor bait traps low on a fence or post near the source. Indoors, the dry climate means fruit flies and gnats usually trace back to one wet spot, such as an overwatered plant, a forgotten potato or a damp recycling bin.

Reading labels and staying safe

Most traps here are devices, using light, glue or color rather than a pesticide. The bait in an outdoor fly trap is different. RESCUE! says its bait is EPA registered, and the EPA explains that pesticides must be registered unless they meet the criteria for a minimum-risk product. For any registered product, the EPA notes that the label is legally enforceable: using the product inconsistently with its labeling violates federal law. Follow the label’s placement, disposal and storage directions.

Practical safety points:

  • Hang sticky ribbons above head height and out of reach of children and pets.
  • Keep bait traps where dogs can’t reach them; the scent that draws flies can draw pets too.
  • Use plug-in traps in standard indoor outlets, keep them away from splashing water and follow the manual.
  • Don’t move a bait trap indoors; RESCUE! states outdoor use only and a 20-foot distance from living areas.

When flies are a sign of something else

A sudden indoor swarm of large flies, especially in one room or near a ceiling, often means something has died in a wall, attic or crawl space. Flies find a dead mouse or bird quickly. Traps won’t fix that; finding and removing the source will. Our guides to a rodent home inspection and rats in the attic explain what to look for, and our mouse trap roundup covers the DIY side of keeping rodents out.

Flies that appear every fall on upper-floor windows can mean gaps in the attic or around siding where insects overwinter. Small flies that keep returning near one drain can point to a broken or leaking drain line under a slab or crawl space. Both are worth raising during an inspection. The specialty inspections hub explains add-on inspections for pests and moisture, and our hiring process guides help you vet who you hire.

Call a licensed pest professional if flies persist after you’ve removed breeding sources and set traps for a couple of weeks, or if you suspect an animal in the structure. If you’re buying or selling on the Front Range and want rodent, moisture or drain issues checked, contact us to connect with a vetted local inspector.

Frequently asked questions

What is the best fly trap for indoors?

For general indoor flies, fruit flies and gnats, a plug-in light trap with a hidden glue cartridge, such as Zevo, works continuously without sprays. For fruit flies specifically, a food-lure trap like TERRO's apple trap is purpose-built. Where there is no outlet, a no-plug trap or a window trap fills the gap.

What is the best fly trap for outdoors?

Scent-bait traps such as RESCUE! disposable bags or the reusable TERRO T380 work best on house flies outdoors. Hang them near the source, such as trash or pet areas. RESCUE! says to hang its traps at least 20 feet from living areas because the activated bait smells strong.

Why are there so many flies in my house all of a sudden?

A sudden swarm of large flies often points to a dead animal in a wall, attic or crawl space, or to garbage or pet waste nearby. Small flies usually trace to overripe produce, damp houseplant soil or a dirty drain. Find and remove the source; traps only catch the adults.

Do fly traps work on fungus gnats and drain flies?

Light-and-glue traps that name gnats, such as Zevo, can catch fungus gnats near houseplants, but letting the soil dry out matters more. Hot Shot's listing says its trap is not intended for fungus gnats or drain flies. Drain flies need the drain cleaned or repaired.

Are fly traps safe around kids and pets?

Light, glue and window traps are described in their listings as spray-free or non-toxic, but sticky ribbons should hang out of reach and above head height. Outdoor bait traps should be placed where pets cannot reach them. For any trap whose bait is a registered pesticide, follow the label's placement and disposal directions.
