How to control snow fleas getting inside ?

[AN3]

Since beginning of November there are tiny insects coming inside the house through the floor level windows, French doors and entry door, into the living room. There is gravel and pavers outside, then a bit of a plant patch. They come once I open the windows,  more so in the evening when it's cooler. They also appear when the windows are closed ?!? Although they are double glazed. 

I searched and they are called snow fleas or springtails, they are not real fleas but they jump like them. They come in all sizes, the biggest get to about 4mm long. 

Outdoor barrier Mortein spray did not work, also the type of outdoor solution that you spray via a hose from a container from Bunnings did not work. I found the information about using diatomaceous earth which I sifted in front of the windows on the gravel outside (I used to keep flower pots there, have moved them away since this started so that to expose the gravel to the sun and not provide any cover for any moisture). 

This also did not work. Every day I manually crush them with tissues, then they come again... sometimes I use the vacuum cleaner.

Attaching a photo (zoom in for a better view) and 2 links with info I found.

Would be grateful for any help on how to get rid of them. 

Thank you,

Welcome to the Bunnings Workshop community @AN3. It's fabulous to have you join us, and many thanks for your question about deterring insects.

Springtails, also known as "snow fleas," can be challenging to manage, particularly in environments with ample moisture. To control them indoors, start by reducing humidity levels since they thrive in damp conditions. A dehumidifier should be used in the affected rooms, with the aim of keeping the humidity below 50%. Ensure proper ventilation in moisture-prone areas such as bathrooms, kitchens, and laundry rooms. Fix any leaks or water seepage around windows, doors, and plumbing. Cleaning the area thoroughly is also essential; vacuum carpets and floors to remove any debris that could harbour springtails, and empty the vacuum cleaner promptly to prevent re-infestation. Sealing gaps around windows, doors, and skirting with silicone or weatherstripping will help prevent their entry. You might also consider using indoor insecticides.

For outdoor control, focus on removing their breeding grounds. Since springtails are attracted to moisture, check for any sources of standing water, such as clogged gutters, overwatered soil, or pooled water around your foundation. Adjust irrigation systems to prevent water accumulation and remove organic matter like mulch, leaves, or decaying plant debris near the house. Reapplying diatomaceous earth can be effective, but ensure the area remains dry for it to work properly. 

For additional protection, consider applying a perimeter pesticide treatment specifically designed for springtails around the foundation of your home, paying special attention to window wells, door thresholds, and gravel areas. You might need to employ the services of a professional as they have access to stronger chemicals than what can be purchased off the shelf.

 Persistence is key when dealing with springtails, as eliminating moisture sources is critical to long-term control.

Please let me know if you have any questions.

Thanks, but I was hoping for an insecticide or other substance that could kill them outdoors. The windows in this living room are floor to ceiling, there is a window screen, and there is no way of stopping such tiny insects from getting in through the window screen. 

Also, the French doors while not big, have a metal frame and doorstep so are not perfectly etanche.

Hi @AN3,

Pyrethroid-based insecticides, containing active ingredients like permethrin or bifenthrin, are highly effective for controlling springtails. These chemicals work by disrupting the pests' nervous system, providing a rapid knockdown effect. To use them, apply the insecticide around entry points, cracks, crevices, and any areas where springtails are active, such as baseboards, windows, or damp corners. It's essential to follow the manufacturer's instructions for safe and effective application. While pyrethroids are potent, their effectiveness can be enhanced by addressing the root cause of the infestation, such as reducing moisture levels and improving ventilation in affected areas.

As mentioned, you might need to enlist the services of a professional pest exterminator that has access to insecticides that are stronger than those you would find off the shelf. They would also be able to obtain these pyrethroid-based products in concentrate form, allowing them to saturate the exterior of your home. There is likely insufficient product in the pre-mixed packs to effectively create a barrier around your home.

Thank you, will use this one then.

Ventilation is OK indoors and the dehumidifier doesn't find much to do as humidity level indoors is ok. The problem is the outdoor area where they come from, and in maybe 15 years here, it has never happened and I have never seen these snow fleas before.
