    I know an engineer who had several ponds near his property who built an elaborate contraption to attract and electrocute them. He killed tens of thousands. Hundreds more ignored it and bit him anyway.

      Bug zappers don’t focus on mosquitos. They focus on bugs attracted to light. Mosquitos aren’t particularly attracted to light. They are attracted to body heat and, most particularly, carbon dioxide. Our exhalations draw them near. Then the heat from the veins close to the skin’s surface provide the fine tuned target. So, to attract mosquitos, emit carbon dioxide which then draws near to a body temperature heat source, which then zaps or drowns them. This drowning is accomplished by having the mosquitos attracted to a suction which then blows them into water with a bit of soap in it.

    Put out a dedicated standing water source but lace it with eco-friendly Bti that kills the larve. (It doesn’t harm people/pets/birds/other insects)

    Gotta geek out a tiny bit.

    Assuming my uncited research from a decade+ ago is correct …

    Citronella was actually extracted from the “Lemon Eucalyptus / Lemon-scented Gum” tree, formerly known as Eucalyptus citriodora but more accurately known as Corymbia citriodora.

    The “Citronella Scented Geraniums” never worked much at all to repel mosquitoes. It was essentially the placebo effect. I’ve done really lame and totally non-scientific experiments myself. The geraniums simply do not work to any significant benefit. People will literally argue with you day and night about this, but it’s just not true.

    That being said, grow scented geraniums to your heart’s content. Burn citronella candles as if your life depended on it. They smell really good and olfactory cues like this will burn memories into your brain that you’ll treasure when you’re older and fading.
