Mud daubers or mud wasps are not a threatening or aggressive species. They use their venom on spiders to kill and consume them but they hardly ever come near humans, even when humans swat at them. Mud wasps are very helpful in your garden and even in your home, they hunt all kinds of insects that most people hate like spiders and centipedes. They are not likely to bother you but some people are worried they will harm them, their children, or their pets.
So it is important to know how to prevent them and how to get rid of them. These wasps get their name from how they build their nests. They are solitary insects and don’t build large nests so you will never have more than a few in your yard at any one time but the population can grow if left unchecked. They do not live in colonies and if their nest is destroyed they are not usually aggressive and will not attack. They will only attack a human if they are directly threatened by it. So don’t swat a mud wasp and they won’t bother you. They are so non-aggressive they would rather move on and build a new nest than attack you for destroying it.
If you are allergic to the sting of a wasp then you may not know you are. It is not a common childhood allergy test and not something most people think about, I have never been stung by a bee or a wasp so I don’t even know what it feels like. But if you are allergic you will swell up and your life may be threatened so if you have wasps, even mud wasps then you should take precautions and protect yourself when you try to destroy the nest. Don’t try to rip the nest apart to find a queen, with mud wasps there is no queen. Just spray insecticide on the nest and leave it as it is. Move on and do this to every nest you can find. If you get them all and make sure to spray the nest very well the wasps may come back to the nests and die from the residual fumes. You should also make sure to store garbage and compost properly and do not leave food on the ground, especially anything sweet because it will attract insects and wasps to your home.
