said by PSWired:They work if you run them all season so that the population never explodes. Putting one out mid-season won't get them under control.
Curious where you came up with that 'fact'
And the definition of control is a bit unclear, more of shade of gray term instead of black & white
When it comes to mosquitoes, short term immediate area population reduction is pretty much all you can expect
Yea yea, major efforts like swamp draining, community wide poison spraying and other large scale environmental projects can have dramatic effects....
