Electric Fly Killers

Electric fly killers are a popular choice for many UK households, but how long do they take to work? Electric fly killers use UV light to attract flying insects and then electrocute them. They come in two main types: grid-style electric fly killers and glue board electric fly killers.

Grid-style electric fly killers have an electrified metal grid that kills the flies when they touch it. These devices usually take around 30 minutes to start working effectively, as the UV light needs time to draw the flies into its range. Once the device is switched on, you can expect it to be effective within half an hour or so of being powered up.

Glue board electric fly killers also use UV light to attract flying insects, but instead of using electricity, these devices trap them with sticky glue boards, which need replacing every few weeks, depending on usage levels. Glue board models generally start working almost immediately after being turned on – typically within 5 minutes – as there’s no waiting period required for their effectiveness like with grid-style models.

Electric Fly Killers are a quick and efficient way to rid your home of flies, but they may not be suitable for all situations. Chemical Fly Killers offer an alternative solution that can take longer to work but may be more effective in some cases.

Key Takeaway: Electric fly killers are a popular choice for UK households, and come in two main types: grid-style and glue board. Grid-style electric fly killers take around 30 minutes to start working effectively, while glue board models start working almost immediately after being turned on (typically within 5 minutes).

Chemical Fly Killers

Chemical fly killers are a popular choice for getting rid of flies. They come in many forms, including sprays, baits, and traps. Chemical fly killers work by killing the adult flies that enter your home or garden.

Sprays: Sprays are one of the most common types of chemical fly killers available on the market today. These products typically contain pyrethrin-based insecticides, which kill adult flies quickly upon contact with them. To use these sprays effectively, it is important to spray all areas where you have seen flies, as well as any potential entry points into your home or garden, such as windows and doors. It is also important to note that some sprays may require multiple applications before they become effective at killing off all the adult flies in an area.

Baits: Baits are another type of chemical fly killer which can be used both indoors and outdoors to get rid of pesky flying insects like houseflies and fruitflies. These baits usually contain food attractants combined with insecticides which lure the adult flies towards them before eventually killing them off after ingestion or contact with their skin or wings. When using baits, it is important to ensure that they are placed away from children’s reach since they may contain toxic chemicals which could be harmful if ingested accidentally by humans or pets alike.

Traps: Traps are another form of the chemical fly killer which can be used both indoors and outdoors, depending on what type you choose to purchase (some traps will only work inside while others will only work outside). These traps usually consist of a sticky adhesive material spread over a surface such as cardboard or plastic sheeting so when an unsuspecting fly lands on it, they become stuck until eventually dying due to dehydration caused by being unable to escape from the trap’s surface area. Some traps even include pheromone lures designed specifically for attracting certain species like houseflies making them more effective than other types of chemical fly killers out there.

Overall, chemical fly killers offer an effective way for people looking for quick results when trying to get rid of annoying flying pests around their homes or gardens without having to resort to drastic measures such as fumigation etc. However, it is important not to forget about safety precautions when using these products – especially if you have young children living in your household who might accidentally ingest something poisonous if left unattended.

Chemical fly killers are a great way to quickly and effectively get rid of flies, but it’s important to remember that they contain hazardous chemicals. Now let’s take a look at natural fly killers as an alternative solution.

Key Takeaway: Chemical fly killers, such as sprays, baits and traps, are an effective way to quickly get rid of flying pests. However, it is important to take safety precautions when using these products around young children or pets.

Natural Fly Killers

Natural fly killers are an increasingly popular way to get rid of those pesky insects without the use of harsh chemicals. These natural methods can be a great alternative for people who don’t want to expose their family or pets to potentially dangerous substances.

One of the most common types of natural fly killers is sticky traps. Sticky traps are simple pieces of paper or cardboard coated with a glue-like substance that attracts and captures flies when they land on them. They work quickly but need to be replaced regularly as they become covered in dead flies over time.

Another type of natural fly killer is water traps, which involve filling a container with soapy water and placing it near where you’ve seen flies congregating. The soap breaks down the surface tension on the water, causing any flying insect that lands on it to drown quickly and effectively. This method works well if you have an infestation inside your home but it may not be suitable for outdoor areas due to rain diluting the solution too much for it to remain effective over time.

A third option is using herbs and spices such as basil, mint or cayenne pepper sprinkled around windowsills or doorways where flies enter your home – this will help repel them from entering in the first place. You could also try hanging bunches of dried herbs such as lavender or rosemary near windows and doors; these fragrances act as deterrents against flying insects like houseflies and mosquitoes alike.

Finally, there are electronic bug zappers available which emit ultraviolet light waves that attract bugs into an electrically charged grid – killing them instantly upon contact. While these devices do work quickly, they should only be used outdoors since they can produce ozone gas indoors which can irritate eyes and lungs if inhaled in large amounts over long periods of time.

Natural fly killers provide an effective way to keep pests away without resorting to harsh chemical solutions, making them perfect for anyone looking for a more eco-friendly approach.

Key Takeaway: Natural fly killers are a great eco-friendly alternative to chemical solutions. Options include sticky traps, water traps, herbs and spices, and electronic bug zappers. Each has its own advantages and should be used in the right environment for maximum effectiveness.


In conclusion, when it comes to how long do fly killers take to work, there is no one-size-fits-all answer. Electric fly killers are the quickest option for eliminating flies from your home or garden, but they come with their own drawbacks. Chemical and natural fly killers can also be effective in getting rid of flies but may take longer to show results. Ultimately, the best way to find out which type of fly killer works best for you is by experimenting with different options until you find the right fit.
