I hate wasps and I worry about one of my little ones being stung for being in the wrong place at the wrong time. I am always on the watch for those flying nuesences and we have a ton of them. So I am always making sure to have wasp spray on hand. While insecticides are usually not that expansive it is still money I hate to spend because it just goes up into the air. So it is really nice when their are coupons available.
