The Leader (Nelson) - - YOUR HEALTH -

Con­ser­va­tion groups and in­di­vid­u­als who have used Ve­spex say it’s in­cred­i­bly ef­fec­tive at wip­ing out wasps.

‘‘It’s an amaz­ing tool that we have,’’ says DOC Nel­son Lakes senior bio­di­ver­sity ranger Nik Joice.

‘‘When the wasp num­bers get up high here the hum of the wasps in the trees, it’s all you hear.

‘‘We put the Ve­spex bait out and the next day you go into the forest and you can hear the birds singing, it’s just amaz­ing. It’s like a switch.’’

Vic­to­ria Univer­sity in­sect ecol­o­gist Phil Lester, who is lead­ing the Na­tional Sci­ence Chal­lenge to de­velop bi­o­log­i­cal con­trols for wasps, says Ve­spex is mak­ing a ‘‘huge dif­fer­ence’’.

Friends of Ro­toiti found­ing mem­ber Bryce Buck­land says prior to fipronil, he had to track down and poi­son wasp nests man­u­ally.

With Ve­spex, he can put out bait sta­tions and knock out en­tire wasp pop­u­la­tions overnight. sum­mer. Learn more­spex.html.
