Wasps that build a nest on your home are a headache. You can't enjoy being outside if you have a lot of wasps buzzing around your garden; some are also likely to get into your house.
So, you may be looking for ways to get rid of the nest. You've seen wasp sprays that say that they can kill off nesting wasps effectively. What should you think about before you try to spray the nest yourself?
Is the Nest Accessible?
Wasps often build nests in nooks and crannies high up on roofs. This makes the nests hard to reach from the ground. Even if you use a long-handled spray, you may not have enough reach to coat the nest effectively. You may kill some wasps but not all of them.
If you're comfortable up a ladder, you may decide to use that to get to nest height so you can spray more effectively. However, this isn't always a safe thing to do. Bear in mind that as soon as you start spraying, you'll disturb wasps in the nest. Some may come out and target you. It's hard enough to stay up a ladder safely at the best of times. If you have to contend with wasps swarming around you, then you could easily lose your balance.
Do You Have Protective Gear?
Your nest could have hundreds of wasps in it. While you might spray it when they are settled down for the night in the hope they'll be quiet and sleepy, they'll perk up pretty quickly as soon as you go near the nest with a spray.
Wasps can get very aggressive when they feel threatened. As soon as you start spraying stuff onto and into their nest, they could go into attack mode. You'll be their target. They'll want to sting you.
Remember that the spray won't work on the wasps straight away. It doesn't kill them immediately. So, you'll have to contend with potentially a lot of angry wasps until you can get away.
To reduce the chances of getting stung, you need to be wearing gear that protects you. Basically, you need complete body and head coverage. Any skin you leave exposed could get stung.
Rather than removing the nest yourself, it may be easier and safer to call in a professional wasp exterminator. They have the sprays, equipment and protective gear they need to exterminate wasps safely and effectively.
