How to Get Rid of Flies
The Complete Southland Guide

Why Flies Are a Problem in Southland

Southland's mix of rural land, mild summers, and settled weather creates ideal breeding conditions for flies. Farms, lifestyle blocks, and even suburban homes near compost or pet waste can produce hundreds of flies a week. Beyond being annoying, flies carry bacteria — they land on waste, then on your food and kitchen surfaces. In a commercial kitchen, they're a compliance issue.

What Attracts Flies

Flies are drawn to three things:

• Food waste — bins, compost, food scraps, pet food left out
• Organic matter — pet waste, manure, grass clippings, rotting fruit
• Warmth & moisture — sunny windows, drains, damp areas

Remove these and you remove the breeding ground. That's the foundation of all fly control.

DIY Methods That Actually Work

1. Apple Cider Vinegar Trap

Fill a jar with apple cider vinegar and a drop of dish soap. The vinegar attracts flies; the soap breaks the surface tension so they sink. Works well for fruit flies and small infestations. Won't touch a big housefly problem.

2. Fly Screens & Doors

The most effective long-term prevention. A good fly screen on windows and doors stops most flies getting in. Check for tears and gaps — flies need surprisingly little space.

3. Bin Management

Keep bin lids tight, rinse food packaging before recycling, and move wheelie bins away from doors and windows. Clean bins periodically with bleach or vinegar. This is the single biggest lever for most homes.

4. Fly Spray & Traps

Retail sprays kill individual flies but don't address the source. UV light traps work well in commercial settings. Both are stopgaps — they reduce numbers without solving the breeding problem.

Natural Fly Repellents

Some plants and scents help deter flies:

• Basil, mint & lavender — plant near doors and windows
• Citronella candles — useful outdoors for short periods
• Essential oils (eucalyptus, lemongrass, peppermint) — dilute and spray around entry points
• Cloves & lemon — a halved lemon studded with cloves is an old-school repellent that works

These help, but they're repellents, not eliminators. If you already have a breeding source on your property, natural methods won't keep up.

When to Call a Professional

DIY methods stop working when:

• You're killing flies every day and the numbers aren't dropping
• You run a food business and flies are a compliance risk
• The breeding source is somewhere you can't easily reach (roof void, drains, subfloor)
• You've tried everything and they keep coming back

Professional fly control works because it targets the breeding source directly and leaves a residual barrier that keeps killing flies for weeks — not just the ones you can see today. One treatment typically gives 4–6 weeks of protection.

FAQ

What is the fastest way to get rid of flies?

Remove the breeding source (bins, food waste, pet waste) and install fly screens. For immediate reduction, a professional residual treatment kills flies for weeks. Retail spray only kills what you can see right now.

What smell do flies hate?

Flies dislike strong scents — basil, mint, lavender, eucalyptus, lemongrass, and cloves. Planting these near entry points or using essential oils can help deter them, but won't eliminate an established problem.

How do I keep flies out of my house?

Three steps: fit fly screens on windows and doors, manage your bins (tight lids, away from the house), and remove standing organic matter. If flies are still getting in, a professional barrier treatment sorts it.

How much does professional fly control cost?

For a standard Southland home, fly control is typically $120–$250. See our pricing page for full details — and remember, we beat any written quote.
