There’s loads of wasps hanging around my windows and door in back garden. Everytime I open the window I get around 1-3 come inside. They seem to be very attracted the my garden wall. Can you recommend anything to get rid of them? Thanks
There could be several reasons why they’re hanging around your garden wall. One is they may have been hibernating in cracks and crevices and are finally emerging now with the change of seasons. Another could be they are forming nests close by and are using the wall as a staging platform. Or there could be some kind of food in the garden they’re attracted to which is keeping them around. Regardless, they can be intimidating and based on your message, I think you need to do some kind of treating if you want them to go away.
If you review our WASP CONTROL ARTICLE, you’ll see we have two sprays you might consider using. The CYPERMETHRIN is a true pesticide and will both repel and kill them if they land on treated surfaces. This would be what most people will spray around the house for keeping wasps and other invasive pests away. It’s an excellent repellent and works on just about anything that might try to get on or in the home.
The other option is the INSECT REPELLENT. This product is not an insecticide but rather a simple repellent. Made with food grade ingredients, it’s mostly used as a paint additive to help repel insects but it can also be used as a spray. Like the cypermethrin, it can be applied over plants and buildings without any risk or danger of hurting them.
Lastly, the FAKE WASP NEST is a visual repellent we’ve had great success using around the home to ward off unwanted wasp activity. Set one out per side of the home where you see them active and the nest should deter the activity.
