That's what I tell my kids "wasps are good bugs!" Thanks for the information about fennel. I've never grown it before. I wonder if it can be perennial in zone 7?.My experience as well. Next to ladybugs, wasps are my most important insect predator. I grow peppers under cages with floating row covers, to get pure seed. Protected by the covers, the aphid population inside can explode. Once enough peppers have set, I open one side of the cage - and within a day, wasps are swarming on the aphids. After a week or so, there is hardly an aphid to be found... and at that point the ladybug & lacewing larvae control the aphids.
Interesting about the fennel, I had no idea it could attract wasps. A lot of it grew wild when I gardened in California, not sure it would survive winters here... might be worth looking into. Okra attracts large numbers of wasps too, not sure if they are there for the plants, or for the aphids present.
Every year I grow either a yardlong bean or a cowpea in each of my gardens, chiefly because they are very effective in attracting wasps & ladybugs. The wasps on those plants are numerous, but far less aggressive than they would be elsewhere - even yellow jackets and hornets. The nectar seems to intoxicate them, they leave me alone as long as I move slowly through the row.
