For common flies around a patio, start by removing food and breeding sources, then use a trap suited to the location. An odor-baited fly bag belongs away from the dining area; a large electric zapper is not the default answer to every flying insect.
First identify the problem. House flies around garbage, fruit flies near fermenting produce and biting mosquitoes need different approaches. The options below address nuisance flies and do not promise mosquito control.
Two practical trap formats
| Option | Useful setting | Main limitation |
|---|---|---|
| RESCUE Outdoor Disposable Fly Trap, two-pack | A yard with space to put the lure away from people | Noticeable odor; outdoor use only |
| Catchmaster sticky fly ribbons, 20 rolls | A nearby indoor garage or utility space permitted by its label | Exposed sticky surface; poor fit over dining tables or within reach of people and animals |
1. RESCUE Outdoor Disposable Fly Trap
The verified two-pack uses a water-activated attractant to draw nuisance flies into a disposable bag. It is worth considering near an outdoor problem area when you can provide the separation the manufacturer calls for.
Placement matters: RESCUE recommends roughly 20 feet of separation from patios, decks and home entrances. Follow the actual label, keep it out of reach of children and pets, and do not bring it indoors. The odor is a significant drawback, so this is a poor choice for a small balcony without an appropriate place to hang it.

2. Catchmaster sticky fly ribbons: for a nearby indoor space
The verified 20-roll pack provides a simple adhesive-capture alternative. The current listing describes indoor use in kitchens, garages and barns. Consider it only for a nearby indoor space permitted by its label, not as an exposed-patio trap.
Limitations: adhesive strips are visible, can collect dust and may catch non-target animals if poorly placed. Keep them away from children, pets and wildlife; never hang one over exposed food or a dining table. Follow the package’s placement restrictions and replace the strip as directed.
Do the cleanup before adding more traps
- Remove pet waste promptly and keep garbage containers closed.
- Clean spills, rinse food residue from recyclables and clear fallen fruit.
- Cover serving dishes and clear plates rather than leaving scraps outside.
- Inspect drains, compost and other damp organic material if flies keep returning.
- Repair screens and close doors to reduce movement between patio and kitchen.
University of California IPM’s fly guidance emphasizes sanitation and exclusion. Traps can complement that work but do not remove a breeding source.
What about an electric bug zapper?
A light that kills some flying insects is not evidence of effective control of the particular pest bothering you. UC IPM cautions against using zappers near food because insect fragments can contaminate the area. Do not put one above a grill or dining table, and do not assume an outdoor unit is appropriate indoors.
When should you get help?
A sudden large number of flies, a persistent smell or repeated activity despite cleanup can indicate a hidden source. A pest-management professional can help identify the species and source before you buy more equipment. If using any pesticide, use only a product labeled for the pest and location and follow every label restriction.
