Old wasp nests can leave behind pheromones/ smells that attract other wasps. These lingering chemicals signal to new queens that the site may be suitable for establishing a new colony. Additionally, the scent can provoke aggressive behavior in wasps that recognize it, increasing the likelihood of them defending the area. Caution is advised around old nests, as they can draw in wasps looking to settle.
Reduced Airflow: Bee colonies / wasp nests can clog the chimney flue and vents, leading to insufficient ventilation and potentially trapping dangerous combustion gases, such as carbon monoxide, inside the home. This can be fatal. If the wasp nest is in a standard air brick with no appliance vent it will not be fatal but needs treatment
High Risk of being attacked do not remove the internal vent covers. Wasptec provide a variety of removal services and methods to help future proof your home. Contact your pest controller for more info.
If the wasp nest is in an air vent, it’s crucial to seal the back of the vent before treatment to prevent insecticide and wasps from entering your home. Here’s how to do it: ONLY DO IF SAFE
Make sure everything is tightly sealed to avoid any leakage. Use black tape if possible, this will ensure the wasps do not have a light source. Wasps are attracted to light.
Keep in mind high risk areas such kitchen /bathroom etc
Wrap at least a double layer of tinfoil over the back of the air vent, ensuring there are minimal gaps. Be careful not to rip the foil.
Masking Tape
Masking Tape: Use black masking tape to seal any gaps around the edges of the tinfoil to ensure no insecticide escapes into the house.
Alternative Method
You can also cut a piece of card (such as from a cereal box) to the size of the vent. Cover the back of the vent with this card and seal the edges with strong masking tape, making sure it is secure and there are no gaps for insecticide to pass through.
Reduced Airflow: Bee colonies / wasp nests can clog the chimney flue and vents, leading to insufficient ventilation and potentially trapping dangerous combustion gases, such as carbon monoxide, inside the home. This can be fatal. DO NOT use fires or appliances that need the vents and chimneys to release gasses and / or need them for ventilation. The nest might be blocking the or reducing the air flow which can cause harmful gasses to build up. In exterme cases this can be fatal. In addition, the reduced airflow can cause damage to your appliances, overheating, fire etc.
DO NOT USE until confirmed safe to do so by a qualified professional. Keep in mind, if not treated, removed or eradicated etc, the nest will continue to grow leading to increased risks.
High Risk Reduced Airflow: Bee colonies / wasp nests can clog the chimney flue, vents, extractors leading to insufficient ventilation and potentially trapping dangerous combustion gases, such as carbon monoxide, inside the home.
This can be fatal.
Damage can also be caused to appliances causing pressure build up, explosion, fire and a variety of other high risk situations. DO NOT USE until confirmed safe by a suitable professional.
High Risk Bee colonies / wasp nests can squeeze thorugh tiny gaps - wasps can chew through certain materials such as plasterboard.
