Suddenly, they start crawling and flying around windows, doors, or the patio: flying ants often seem to appear out of nowhere and can quickly cause concern. Many people affected wonder: What can be done about flying ants? Are they dangerous? And how can flying ants be controlled if they keep reappearing?
In this article, we explain what lies behind flying ants, why they appear particularly on warm days, and when action is necessary.
What are flying ants?
Flying ants are not a separate species of ant. They are sexually mature ants, usually young queens and males. During the so-called nuptial flight season, they leave the nest to mate and establish new colonies.
After the mating flight, the male ants usually die after a short time. Mated young queens shed their wings and search for a suitable place to build a new nest. This can lead to the formation of new ant colonies.
Why do flying ants suddenly appear?
Flying ants are particularly common on warm, humid days. They often appear after rain or when humidity is high. Many ants then swarm at the same time. This often makes it seem as though they have suddenly appeared out of nowhere.
Common places where they are found include:
- Windows and windowsills
- Patio doors and balconies
- Light sources
- Kitchens and pantries
- Joints, cracks, and skirting boards
- Facades and gaps in walls
- Garden areas near the house
If flying ants only appear outdoors, action is usually not necessary. However, if they are repeatedly found indoors, the cause should be investigated.
Flying ants in the house: What does it mean?
Flying ants in the house can have various causes. Individual ants may have entered through open windows or doors. However, if many winged ants appear or they are repeatedly seen in the same places, this may indicate an existing colony inside the building or in the immediate vicinity.
Pay particular attention to these signs:
- Ants emerge from cracks, joints, or areas of the wall
- Ant trails form indoors
- Flying ants reappear every year
- Ants gather around windows or light sources
- New ants appear after removal
In these cases, it is usually not enough to remove only the visible ants. The key is to find out where the ants are coming from and whether there is a nest.
Are flying ants dangerous?
Flying ants are generally not dangerous to humans. They do not usually sting and typically do not cause any direct health problems. Nevertheless, they can become very bothersome, especially when they enter living spaces in large numbers.
The problem becomes particularly serious when an ant nest is located inside or directly next to the house. Nests can be found, for example, in wall cavities, under floor coverings, behind skirting boards, in insulation, or in cracks in the building.
What can you do about flying ants?
Anyone wondering, “What can you do about flying ants?” should first determine whether it is a short-term swarming event or a genuine ant infestation.
For the occasional flying ants, start with these simple immediate measures:
- Keep windows and doors closed
- Install fly screens
- Reduce light sources in the evening
- Seal food in airtight containers
- Remove crumbs, sugar residue, and food scraps immediately
- Seal entry points such as joints, gaps, and cracks
- Carefully remove individual insects
These measures are mainly effective against individual insects. However, if an ant trail is visible or ants appear regularly, the colony should be targeted directly.
How to control flying ants: What really helps?
Anyone wanting to control flying ants should not focus only on the flying insects themselves. They are often just a visible sign that an ant colony is nearby. If only individual ants are removed, the cause remains.
A contact spray alone often only affects the ants that are hit directly. As a result, the nest is usually not reached. That is why, in the case of recurring infestations, bait is more effective: the worker ants consume it and carry it back to the colony.
Solution for an ant infestation: Advion Ant Gel
A proven solution for controlling ants is Advion Ant Gel. The gel is applied specifically along trails, at entry points, and in areas where ants are active. Worker ants consume the bait and carry it back to the colony.
The advantage: It reaches not only the visible ants but also those in the nest. This is particularly important when flying ants in the house indicate an existing ant colony.
Advion Ant Gel is particularly suitable for:
- Ant trails in the house
- Ants in the kitchen, pantry, or living area
- Recurring ant infestation
- Ants on window frames, skirting boards, or in joints
- Suspected nest near the building
If you want to know what helps against flying ants, you should not only remove the visible ants when the infestation recurs, but also target the colony. An ant bait such as Advion Ant Gel is a suitable product solution for this.
What works better against flying ants than spray?
Many people reach for a spray first when dealing with flying ants. Although it often works quickly against visible ants, it usually does not solve the underlying problem. If there is a nest nearby, new ants will keep appearing.
A bait gel such as Advion Ant Gel targets the problem more effectively than a conventional insect spray. The ants take up the bait and pass it on within the colony. This not only reduces visible activity but also reaches the colony.
Household remedies for flying ants – useful or not?
Many people initially try to get rid of flying ants with household remedies. These include vinegar, lemon, baking soda, or essential oils. Some remedies may temporarily drive ants away or disrupt their trails.
However, household remedies usually do not solve the nest problem. If an ant colony is located inside the building or directly next to the house, the ants often do not disappear permanently. In this case, a targeted ant bait such as Advion Ant Gel is the better solution.
Prevent flying ants
It is not possible to completely prevent the natural nuptial flight. However, you can reduce the risk of flying ants entering or settling in your home.
Effective prevention:
- Use fly screens on windows and doors
- Seal cracks, joints, and gaps
- Keep food well sealed
- Dispose of waste regularly
- Do not leave pet food out in the open
- Reduce moisture in the home
- Monitor ant trails at an early stage
The earlier an ant infestation is detected, the easier it is to control.
Conclusion: Flying ants are often harmless but may indicate an infestation
Flying ants are part of the natural life cycle of ants. In the garden or outdoors, they are usually visible only for a short time and often disappear on their own. However, if flying ants appear indoors or keep coming back, it is worth taking a closer look.
Anyone who wants to control flying ants should not simply remove the visible insects. The key is to target the ant colony directly. Advion Ameisengel can be an effective solution.
Garden ant or pharaoh ant? Make the right decision with expert knowledge
When ants are found in a home or business, accurate species identification is crucial. While garden ants often enter from outside and can usually be contained effectively, pharaoh ants live permanently in warm indoor spaces and require particularly careful treatment.
In the online training course “Expert Knowledge: Ants,” you will learn:
- reliably identifying the most important ant species and deriving the appropriate control strategy,
- why a targeted baiting strategy is usually more effective than uncontrolled spraying and how to avoid common mistakes,
- systematically inspecting, assessing, and documenting an ant infestation,
- selecting suitable products for specific applications and using them safely,
- complying with legal requirements such as the Biocidal Products Regulation, HACCP, and the Infection Protection Act,
- preventing a renewed infestation through effective prevention and follow-up care.
The training comprises ten online lessons with instructional videos, PDF materials, knowledge checks, and a final exam. It takes approximately 90 minutes to complete. After successfully completing the course, participants receive a certificate of attendance and achievement.
Ideal for property management companies, catering businesses, hotels, food companies, facility management, and other users who want to reliably assess and professionally treat ant infestations.
Use biocides safely. Always read the label and product information before use.
