WASP WISDOM Before the season for wasps is quite over,

and while what I hope is the final assault of the pests continues, I must hasten to thank more than a dozen people who have written me about the treatment of wasp nests. It is impossible for me to list proprietory articles, but I am assured that there are a number of effective remedies which do not require a note from a magistrate and the signing of the poison book. Speaking of a DDT treatment, one reader remarks, 'It is, however, a mistake to use it at night. Rain or dew will spoil it by, next morning and the powder will probably be useless. It should be used by day when the wasps are flying. They will then take it down into the nest when the powder is fresh and most effective.' This appears very sound advice.
