Wasp/hornet trap: a mason jar and a funnel. Put watered down orange juice in the jar. The wasps/hornets are attracted to the fruit juice so they'll go down the funnel but won't be able to find their way out and eventually drown. Pet and kid safe.
Safe wasp trap. A mixture of vinegar, sugar and salt. The wasps are attracted to the sweet and sour scent yet bees don’t seem to be attracted by this sour mixture whereas a honey mix would be a fatal attractant.
