The Story
What Is a Plug In Insect Repellent and How Can It Help You?
If you've ever been kept awake by the whine of a mosquito or woken up covered in bites, you'll know how disruptive insects can be — especially during warmer months or when travelling. The plug in insect repellent format offers a hands-free, no-spray solution that works quietly in the background while you sleep. The Jungle Formula Plug In is an electric device designed for indoor use, releasing an insect-repelling vapour into the surrounding air to protect you and your household. It's a practical option whether you're at home in the UK during summer or preparing for a trip abroad. If you're also planning travel and need broader health protection, browse our travel health range for additional essentials.
Insects such as mosquitoes are more than just a nuisance. The NHS notes that mosquito bites can cause itching, swelling, and in some parts of the world, transmit serious diseases including malaria and dengue fever. Even in the UK, biting insects can cause significant discomfort and disturbed sleep. Having a reliable indoor repellent device is a sensible precaution, particularly if you live near standing water or are visiting a high-risk region.
How Does the Jungle Formula Plug In Work?
The device works by gently heating a refill — either a liquid vial or an impregnated mat — that contains transfluthrin, a synthetic pyrethroid compound. When warmed, transfluthrin evaporates into the air as an invisible vapour. This vapour acts on the nervous system of insects, repelling and killing mosquitoes and other flying insects that enter the treated space. It does not require any spraying, rubbing, or direct skin contact.
- Plug the device into a standard UK mains socket
- Insert the compatible refill mat or liquid vial
- Switch the device on and allow 10–15 minutes for the vapour to disperse
- The active ingredient transfluthrin is released continuously while the device is switched on
- Replace the refill when the indicator shows it is exhausted or after the stated number of nights
Who Should Use the Jungle Formula Plug In?
This product is suited to anyone who wants effective indoor insect protection without applying a topical repellent to their skin every night. It's particularly useful for people who find sprays or lotions inconvenient, those with sensitive skin who prefer not to use DEET-based topical products, and households where multiple people need protection simultaneously.
- Adults seeking overnight mosquito protection at home or in holiday accommodation
- People travelling to regions where mosquitoes are prevalent
- Those who prefer a no-touch, no-spray repellent method
- Households wanting continuous room-wide protection during summer months
It is not recommended for use in rooms occupied by fish tanks or aquariums, as transfluthrin is highly toxic to aquatic life. Always ensure adequate ventilation when the device is in use.
How Does the Jungle Formula Plug In Compare to Topical Repellents?
| Feature | Jungle Formula Plug In | Topical Spray/Lotion Repellent |
|---|---|---|
| Application method | Electric device — no skin contact needed | Applied directly to exposed skin |
| Coverage area | Whole room | Treated skin areas only |
| Duration per use | Up to 8 hours per night / 45 nights per refill | Varies; typically 4–8 hours per application |
| Suitable for sensitive skin | Yes — no direct skin contact | Depends on formulation; some may irritate |
Is the Jungle Formula Plug In Suitable for All Environments?
The plug in insect repellent is designed for indoor use only and should not be used in outdoor spaces, as the vapour will disperse too quickly to be effective. It works best in enclosed rooms such as bedrooms, living rooms, or hotel rooms. Ensure the room has some ventilation — a slightly open window is sufficient — to prevent vapour build-up to uncomfortable levels. Do not use in rooms smaller than 15 m² without ventilation.
If you're also dealing with skin reactions from insect bites, our skin care range includes soothing creams and treatments to help manage irritation. Always read the product label carefully before use, and store the device and refills away from children and heat sources.
This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Jungle Formula Plug In
What Is the Jungle Formula Plug In and What Is It Used For?
The Jungle Formula Plug In is an electric indoor insect repellent device that uses heat to vaporise transfluthrin — a synthetic pyrethroid — into the surrounding air. It is used to repel and kill mosquitoes and other flying insects inside enclosed spaces such as bedrooms and living rooms. It is particularly useful during summer months in the UK and when staying in accommodation abroad where mosquitoes are active. Unlike topical repellents, it requires no application to the skin, making it a convenient option for overnight protection.
What Do You Need to Know Before Using the Jungle Formula Plug In?
Before using this device, read the following contraindications and warnings carefully:
- Do not use in rooms containing fish tanks, aquariums, or other aquatic animals — transfluthrin is highly toxic to fish and aquatic invertebrates
- Do not use in completely unventilated, sealed rooms — always ensure some airflow
- Keep the device and refills out of reach of children and pets
- Do not use near open flames, gas hobs, or other heat sources
- Cats and birds may be sensitive to pyrethroid compounds — consult a vet before use if pets will be in the room
- People with asthma or other respiratory conditions should use with caution and ensure good ventilation
- Do not touch the heated element or refill while the device is switched on
- If you are pregnant or breastfeeding, consult your pharmacist or GP before use
Known interactions:
- No known drug interactions when used as directed in a ventilated room
- Avoid simultaneous use with other pyrethroid-based insecticide devices in the same room
How Should You Use the Jungle Formula Plug In?
Using the device correctly ensures you get the most effective protection. Follow these steps each time you set it up:
- Remove the device from its packaging and insert the refill mat or liquid vial as directed on the label
- Plug the device into a standard UK mains socket at a low level — ideally near the floor where insects tend to fly
- Switch the device on at least 10–15 minutes before you need full protection in the room
- Ensure the room has some ventilation — a slightly open window or door is sufficient
- Leave the device running throughout the night or for the duration you require protection
- Switch off and unplug when not in use for extended periods
- Replace the refill when the indicator shows it is empty or after the stated number of nights
| Indication | Age Group | Usage | Duration |
|---|---|---|---|
| Indoor mosquito protection | Adults | One device per room | Up to 8 hours per night; up to 45 nights per refill |
| Indoor mosquito protection | Children (with adult supervision) | Ensure ventilation; keep device out of reach | As above; consult pharmacist for young children |
If you are travelling and need additional protection against insect-borne illness, our first aid range includes bite and sting treatments to complement your insect repellent routine.
What Are the Possible Side Effects of the Jungle Formula Plug In?
Side effects are uncommon when the device is used as directed in a ventilated room. However, some people may notice the following:
Common side effects:
- Mild eye irritation if sitting very close to the device in a poorly ventilated room
- Mild throat or nasal irritation in sensitive individuals
Less common side effects:
- Headache in enclosed, poorly ventilated spaces
- Skin irritation if the refill or device is handled directly while warm
- Coughing or wheezing in people with pre-existing respiratory conditions such as asthma
If you experience any of these symptoms, switch off the device, ventilate the room, and move to fresh air. If symptoms persist, seek medical advice. The NHS advises that anyone experiencing a severe allergic reaction — including difficulty breathing, swelling of the face or throat, or a rapid heartbeat — should call 999 immediately.
How Should You Store the Jungle Formula Plug In?
Correct storage keeps the product effective and safe between uses. If you're also managing other health products at home, our allergy and hay fever range has further guidance on managing seasonal sensitivities alongside insect protection.
- Store below 25°C in a cool, dry place away from direct sunlight

Frequently Asked Questions
Where can I buy Jungle Formula Plug In online in the UK?
You can buy the Jungle Formula Plug In directly from Cured Pharmacy, a GPhC-registered UK online pharmacy. It is available without a prescription and can be ordered for home delivery. No appointment or consultation is required for this over-the-counter product.
How does the Jungle Formula Plug In work in a room?
The device heats a refill containing transfluthrin, a synthetic pyrethroid, which evaporates into the air as an invisible vapour. This vapour disrupts the nervous system of mosquitoes and other flying insects, repelling and killing them within the treated space. It works continuously while plugged in and switched on, providing room-wide protection without any skin contact.
How do I set up the Jungle Formula Plug In step by step?
Insert the refill mat or liquid vial into the device as shown on the packaging, then plug it into a standard UK mains socket. Switch it on at least 10–15 minutes before you need protection, and ensure the room has some ventilation such as a slightly open window. Replace the refill when it is exhausted or after the stated number of nights of use.
How long does one Jungle Formula Plug In refill last?
A single refill is typically designed to last up to 45 nights when used for approximately 8 hours per night. The exact duration may vary depending on the specific refill type, so always check the product packaging for confirmation. Switching the device off when not needed will help extend the life of each refill.
Is the Jungle Formula Plug In safe to use overnight in a bedroom?
Yes, the device is designed for overnight use in bedrooms and is one of the most common ways people use a plug in insect repellent. You should ensure there is some ventilation in the room — a slightly open window is sufficient — and avoid using it in a completely sealed space. If you or anyone in the room has asthma or a respiratory condition, consult your pharmacist before use.
What are the side effects of the Jungle Formula Plug In?
Side effects are uncommon when the device is used correctly in a ventilated room. Some people may experience mild eye, nose, or throat irritation, particularly in poorly ventilated spaces. If you feel unwell, switch off the device, ventilate the room, and move to fresh air; seek medical advice if symptoms persist.
How do I manage side effects from the Jungle Formula Plug In?
If you notice irritation to your eyes, nose, or throat, the first step is to switch off the device and open windows to ventilate the room. Moving to fresh air usually resolves mild symptoms quickly. If symptoms such as wheezing, difficulty breathing, or skin reactions occur, stop use immediately and seek medical advice — you can also contact our pharmacist team for guidance.
Is the Jungle Formula Plug In safe to use around children?
The device should be kept out of reach of children and placed where they cannot touch the heated element or refill. Ensure the room is ventilated when in use, and consult your pharmacist before using around infants or very young children. For baby and toddler-specific health products, you can also browse our baby and toddler range for age-appropriate options.
Can I use the Jungle Formula Plug In if I have asthma?
People with asthma or other respiratory conditions should use this product with caution, as inhaled pyrethroid vapour may trigger symptoms in sensitive individuals. Always ensure good ventilation in the room and consult your GP or pharmacist before use if you have a respiratory condition. If you experience any worsening of breathing symptoms, discontinue use immediately.
Is the Jungle Formula Plug In safe to use near pets?
Transfluthrin is highly toxic to fish and aquatic invertebrates, so never use the plug in near fish tanks or aquariums. Cats and birds can also be sensitive to pyrethroid compounds, so consult a vet before using the device in a room where these pets spend time. Dogs are generally less sensitive, but good ventilation is still advisable.
Who is eligible to use the Jungle Formula Plug In?
The product is suitable for use by adults and older children under adult supervision. It is not recommended for use in rooms with fish tanks, and those with respiratory conditions, pregnant women, or breastfeeding mothers should consult a pharmacist or GP before use. It is an over-the-counter product and does not require a prescription.
What are the alternatives to the Jungle Formula Plug In?
Alternatives include topical insect repellents containing DEET or picaridin, which are applied directly to the skin and are particularly useful outdoors where a plug-in device cannot be used. Mosquito nets and insecticide-treated bed nets are another option, especially for travel to high-risk malaria regions. For a broader selection of travel health products, visit our travel health collection.
How long can I keep using the Jungle Formula Plug In?
You can continue using the device for as long as insect protection is needed, replacing refills as required. There is no maximum duration of use for the device itself, provided it is used as directed and in a ventilated space. If you notice any deterioration in the device or unusual smells, discontinue use and contact the manufacturer.
Can I use the Jungle Formula Plug In outdoors?
No — this device is designed for indoor use only. Outdoors, the transfluthrin vapour disperses too rapidly into the open air to provide effective protection. For outdoor insect protection, a topical repellent spray or lotion applied to exposed skin is a more appropriate choice.
What is the latest research on plug in insect repellent devices?
Research into pyrethroid-based electric vaporisers, including transfluthrin devices, consistently supports their effectiveness at reducing indoor mosquito density and biting rates. Studies published in peer-reviewed journals have found that electric vaporisers can significantly reduce mosquito landings in treated rooms compared to untreated controls. The NHS and Public Health England continue to recommend indoor insect repellent measures as part of malaria and insect-borne disease prevention strategies for travellers.
