Removing a yellow jacket nest can be risky, as these insects are really aggressive. So you must take enough precautions, before removing their nest. If you are allergic, stay away from wasps and wasp nests, and seek professional help. Given here are some tips to remove a yellow jacket nest.
✦If you want to get rid of a yellow jacket nest, it is always better to do it in the late evening or night. Make sure to wear protective gear, like gloves, face mask, hats that cover the ears, goggles, shoes, and clothes (preferably leather) that cover the whole body. This will protect you from their stings.
✦It is advisable to remove a yellow jacket nest before summer, when the colony expands in size. You may either use dust insecticides or aerosol sprays meant for yellow jacket wasp control.
✦If the nest is an aerial one, it will be somewhat easy for you to locate its opening, for spraying the insecticide. Saturate the nest with the insecticide. You must keep an extra can with you, so that you can use it, if needed.
Leave the site, as soon as possible. If you are not sure of the results, repeat the process for the next two days. Follow-up is necessary if you notice activities near the nest.
✦The same method can be followed for removing a wasp nest that is located inside the ground. All you have to do is to spray the insecticide into the opening and repeat it for the next two days. Once you are sure that the insects are dead, close the opening of the nest in the ground, using stone and soil.
In such cases, spray the insecticide through the entrance and leave it open, so that the insects that frequent through the opening, carry the chemical into the nest, thereby causing their death. Repeat the use of insecticide for a few days.
✦If you cannot find the entrance of the wasp nest in the wall, you may drill a hole and spray the insecticide directly into the wasp nest. In such cases, seal the hole, soon after you finish spraying the insecticide. If you find the entry point, make sure to spray the insecticide through it too.
Once done, ensure that the insects are dead, and remove and destroy the nest. In some cases, you may be able to remove the nest without causing any damage to the existing structures.
Otherwise, treat the nest with a long-lasting insecticide that will take care of the larvae inside, if there are any. In short, yellow jacket nest removal can be risky. So, do it with extreme caution. If you are not confident, leave the task for pest control professionals.
