Everything the restaurateur needs to know about food safe spray for front and back of house fly control.

Why you need fly spray in a restaurant.

Where would you be without your customers?

All roads in the industry lead to customer experience. Menus set, procedures in place – everything designed to create that memorable dining experience. And then there is a fly. No matter the teamwork, the preparation, the love; one fly has the potential to spoil it all.

Food Safety Standards means businesses must act to prevent fly problems. Business owners are required to stop flies entering and breeding on the premises and employ measures such as food safe fly sprays to eradicate any issues.

Flies are filthy, transmitting more than 60 diseases. Prolific breeders, one female can lay 130 eggs at a time and up to 700 in a single week.
Restaurants must work to remove potential breeding sites, installing fly wire screens, food safe spray and fly traps to stop infestation.

Prevention is better than cure.

Flies can sabotage a memorable dining experience, making it unforgettable for all the wrong reasons.

How does fly spray work?

Not a fast knockdown

Food Safe Fly Spray is not a fast knockdown product.
The fly ingests the spray and is unable to metabolise it. If the insect wishes to live, it must remove itself from the spray affected area.

Pyrethrin functions well as an insect repellent at lower concentrations. Observations in food establishments demonstrate that flies are not immediately killed, but are found more often on windowsills or near doorways. This suggests, due to the low dosage applied, that insects are driven to leave the area before dying.  Wikipedia Pyrethrin – Use as an insecticide

If the insect is unable to leave the space, say the restaurant is closed up, then the insect will die. The elimination process is gentler than a fast knockdown, as these tiny intruders can leave the space. This is of great benefit in a restaurant setting. It ensures the creatures will not die in the chef’s prep, in your display cabinets or beside the customer.

Very fine micro particles of spray

The dispenser units have a brass solenoid which emits fine particles of spray, small enough to float in the air. Regular supermarket fly spray cans have a finger trigger on the top of the can. This style dispenses a droplet. This droplet is too large to float and falls to the ground. The pyrethrin spray combining with the super fine mist, is the secret.

Positioning of dispensers

Dispensers are positioned according to several factors:

Battery powered and spraying at 5 minute intervals, the Fly Lady Food Safe spray creates a fly free zone. When insects encounter the spray, they are left with no choice except to leave.

Product composition

The composition of the product is very different to fast knockdown fly control products. Fast knock down sprays have synthetic active ingredients that are toxic and not permitted anywhere near food.

The Fly Lady Food Safe Fly Spray boasts an active ingredient derived from flower oils which is toxic only to cold blooded creatures.  

Please note that pyrethrins are harmful to aquatic animals. Spent aerosol cans must be kept out of water ways. Dispensers must not be installed near aquatic or reptile tanks.

Environmentally friendly

“As far as pesticides go, pyrethrum breaks down very quickly. It has relatively low toxicity and is totally biodegradable. It’s a good one to use.” 
Jerry Coleby-Williams from ABC’s Gardening Australia.  To read the full Gardening Australia Pyrethrum fact sheet click here.

Pyrethrum is one of the most commonly used non-synthetic insecticides allowed in certified organic agriculture.

Pyrethrin is nonpersistent. It does not build up in the environment. It does not have a  residual effect. It also lacks photostability. This means the product breaks down in daylight. 

“In the presence of sunlight, pyrethrin 1, a component of pyrethrins, breaks down rapidly in water and on soil and plant surfaces. Half-lives are 11.8 hours in water and 12.9 hours on soil surfaces. On potato and tomato leaves, less than 3% remained after 5 days.”

Automatic Fly Spray

Set and forget 24-hour protection

Automatic fly spray provides set and forget convenience. Using commercial quality dispensers means less handling. Once installed and switched on, the automatic units are self sufficient for six weeks at a time.

The refill procedure

Pro tip: When deciding on the install location, opt for a spot you can reach without a ladder. This ensures refilling units is a simple, time efficient task.

The spray action is not draining on batteries. A set of batteries will last 5-6 refill rounds.
Click here to check out how easy it is to change over a refill can. 

Setting Options

It is recommended units are left switched on while there is fly activity. The continual spray will force flies to leave during trading hours and eliminate whatever is locked in when your closed.

How long will a refill last set on 5 or 7 minutes?
Set at 5 minute intervals a refill will last for 6 weeks spraying every 5 minutes, 24 hours a day.  At 7.5 minutes a refill will last 8 weeks spraying every 7.5 minutes, 24 hours a day.

The 7.5 minute setting is useful at the beginning and end of summer when the fly issue is not at its peak but there are still a few buzzing around creating a nuisance.

Fly Spray for Restaurants.

Pyrethrins are classified as botanical, non-residual contact insecticides that break down readily in the presence of oxygen, light, moisture, and high temperature.

The fact that pyrethrins break down within a short time makes them ideally suited for use in food-handling facilities. They are effective at killing flies at lower dosage rates. Pyrethrins are effective against exposed flying or crawling insects.

“Considered to be among the safest insecticide for use around food”

What is fly spray made of?

Pyrethrum is a plant (Chrysanthemum cinerariaefolium). Pyrethrum is also the name of the crude extract obtained from the flowers of this plant. Be careful not to confuse pyrethrum with pyrethrin. Pyrethrin refers to a more refined extract of pyrethrum. Pyrethroids are synthetic versions of pyrethrin. Pyrethroids accumulate in the environment. The Fly Lady spray uses natural pyrethrin.

Genus Chrysanthemum. Member of the daisy or aster family, Asteraceae. They are perennial plants with a daisy-like appearance.  Growing 30-60 cm in height.  These plants prefer cooler climates.

History of pyrethrin.

Discovered in China and the Near East many centuries ago. The ground flower heads from 2 species was known as “insect powder” and sold in drug stores in the 19th and early 20th Century as “Pulvis Insectis” Pyrethrins constituted the powder’s active ingredients.

Australian pyrethrum

Australia is currently the world’s major grower of pyrethrum daisies.  Up until recently most of the worlds Pyrethrum was grown in The rift Valley, Kenya.  Also 

They are grown around Northern Tasmania and Ballarat, Victoria. The cooler climate is ideal.

Is fly spray bad for humans?

Considered one of the safest insecticides available today.

Resistance to pyrethrin has been bypassed by pairing the pyrethrin with a synthetic synergists called piperonyl butoxide. Together, these two compounds prevent detoxification in the insect, ensuring insect death.

Synergists make pyrethrin more effective, allowing lower doses to be used. Pyrethrins are effective insecticides because they selectively target insects rather than mammals due to higher insect nerve sensitivity, smaller insect body size, lower mammalian skin absorption, and more efficient mammalian hepatic metabolism.

Mammals are less susceptible to pyrethrin than insects primarily because they have a faster metabolic clearance, higher body temperatures and a lower affinity for the pyrethrins.  Go to Science Direct for more about pyrethrin.

When eaten or inhaled, pyrethrins are absorbed into the body. They are absorbed poorly by skin contact. Once inside, they are rapidly broken down into inactive products and are excreted or removed from the body in the urine. 

Pyrethrin is widely used in Australia for

Frequently Asked Questions

The active ingredients in the Fly Lady’s food safe fly spray creates a barrier of fine mist.  The mist, known as a micro mist, floats in the air.  This enables you to create an insect proof barrier with your doors and windows open.  Insects are unable to metabolise the spray. To survive, insects must remove themselves – straight back out that open door.  This means no flies dying in front of your customers or dead flies in the kitchen. Winning!

The fly spray aerosols are manufactured specifically to fit into the automatic dispensers.  They cannot be used without a dispenser.  Chefs don’t have time to be chasing flies! Set and forget using automatic dispensers and get on with the other zillion tasks on your list.

In sunlight, pyrethrin mixture has a half-life of 10–12 minutes, which limits its outdoor uses. As the spray is fine it will float away. Unless you have a very sheltered roofed area, l would not recommend the product for outdoor use.

This will depend on your location. Flies persist for longer in the warmer climates. It will also depend on the variety of fly. The vinegar flies tend to make a nuisance of themselves through the cooler months as well. If you are targeting blow flies, you may be able to switch your units off for the cooler months.

Pyrethrins are commonly used to control insects including flies, vinegar flies, fruit flies, ants, cockroaches, weevils, sand flies and mosquitos. The Fly Lady spray is designed to target flying insects.
Agricultural pest species that have been successfully controlled by pyrethrum include the potato, beet, grape, and six-spotted leafhopper, cabbage looper, celery leaf tier, Say’s stink bug, twelve-spotted cucumber beetle, lygus bugs on peaches, grape and flower thrips, and cranberry fruit worm.

The pyrethrins are a class of organic compounds. Pyrethrin naturally occurs in chrysanthemum flowers and is considered an organic insecticide when it is not combined with piperonyl butoxide. Its insecticidal and insect-repellent properties have been known and used for thousands of years.
Pyrethrin breaks down rapidly, so it does not persist in the environment.
In aquatic settings, toxicity of pyrethrin fluctuates, increasing with rising temperatures, water, and acidity. Aquatic life is extremely susceptible to pyrethrin toxicity. Used aerosol cans must be disposed of appropriately. In a bin or recycle bin depending on your local council.

The Fly Lady Insect Spray is manufactured in Sydney, Australia and subject to Australian health and safety guidelines.
