Destroy mosquito larvae in the rain barrel - tips for prevention and control


If the rain barrel is teeming with small animals, there is usually one thing: mosquito larvae. If you don't fight them right away, you can quickly have a mosquito plague on your neck.

Rain barrel: breeding ground for mosquitoes

In summer, mosquitoes can become a real nuisance. For example, when they are floating around in a large crowd in the garden or even around the house. You cannot completely prevent mosquitoes from floating through your garden, but you can specifically minimize their population. Mosquitoes need standing water to lay their eggs. A rain barrel is therefore the best breeding ground for these insects. However, if you know this, there is a lot you can do to prevent mosquito infestation.

Destroy mosquito larvae in the rain barrel

Removing the mosquito larvae from the rain barrel has top priority. After the larvae hatch from the eggs, they remain on the water surface for a while before flying through the area. However, you can only sit on the surface if the correct surface tension is present. If you want to get rid of the insects, you have to nullify this surface tension.

➤ Tip 1 - vegetable oil:

One way to destroy them is to stifle the insects with oil. All you have to do is drip a few drops of any vegetable oil from the kitchen into the water. The larvae should then die within a very short time.

➤ Tip 2 - detergent:

As an alternative to vegetable oil, you can also drop a little detergent into the water. A tablespoon on a large rain barrel should be enough. You can still use the rainwater for watering in the garden if you use a 100 percent biodegradable product.

➤ Tip 3 - NEUDORFF mosquitos free:

In every gardening trade or in the hardware store you can also buy very special preparations with which the larvae in the water (rain barrels, garden ponds and other waters) can be fought and which are also biodegradable and therefore harmless. These products are made on the basis of protein substances, so that they do not harm people, wild animals, useful insects, fish or other organisms. For example, Products such as the NEUDORFF mosquito free (available here) will completely destroy the existing mosquito larvae.

Prevent mosquito larvae from developing

➤ Tip 4 - cover the rain barrel:

Prevention is better than any mosquito control measure, so you can save yourself a lot of effort and annoyance. It is ideal if you cover your rain barrel with a lid.

Alternatively, you can put a mosquito screen over it in summer. But don't forget the downpipe, because the mosquitoes can slip through there. So you also have to cover this with a fine mesh.

➤ Tip 5 - Empty the rain barrel:

It takes around three weeks for the mosquito larvae to reach the point where they can fly. If you empty the rain barrel completely during this period, you do not need to take any further action.
