A wasp on its own is not difficult to get rid of. Depending on the time of year, it may not even bother you. The loan wasp may be on the hunt for flies or grass hoppers so may not need getting rid of. If the wasp does begin to irritate, then getting rid of it shouldn't be to much of a problem. Solitary wasps are normally rather docile as they don't have a nest to protect and normally lay eggs in there prey. On the other hand you have social wasps that are more aggressive as they have a nest they will protect and will need to be gotten rid of. If you have a wasps nest, the best time to get rid of them is after the sun has set or before the sun rises as they retreat to the nest at this time. With this important piece of information, you can now get rid of the wasps with either the many products that are available or if it is possible, by lighting a fire under the nest and smoking them out. With a fire, the smoke suffocates the wasps although some may leave, but with the nest destroyed, they wont return.
