Snap, crackle, fizz!
That's such a satisfying sound - part of the war on mozzies. We've had them in every home apart from the places we've stayed over winter.
I love animals & respect life, rescuing spiders & catching wasps to put them outside, but mosquitos are different. Biting mozzies & annoying, determined, dive-bombing flies meet a quick end. When we can catch them. When existing bites beginning to itch once again is usually a good indication of a mosquito lurking somewhere close-by.
I once had a thick paperback book with mozzies squashed to the pages inside. Well, it was an ideal way to catch them as the pages were slammed shut. A book, slipper, shoe, newspaper, my hands, dedicated long-handled fly-swat & electronic ultra-violet zapper have all been tried to varying degrees of success.
Any kind of chemical, essential oil or candles are poisonous to birds, so we're unable to use a repellent, either on ourselves, or in a plug-in diffuser. We tried spraying with baby-safe Agua de Colonia & sleeping with a fan blowing, but that didn't work & we'd wake with irritating red bites. So the frequent nightly mozzie hunts are done with hand tools.
You can get a good swing with the fly-swat, but catching a mozzie mid-flight with a back hander from the electic tennis racquet & you know it's fried. Snap, crackle, fizz & a blue spark - aaaaah, the satisfaction.
I'm sure itchy, scratchy, bity, tacky, sticky, sweaty & stinky are the seven dwarves of a Spanish summer 
"But", you may say, "You live in Spain & mozzies are a part of it so get used to it."
Yeah, I know, but an unwelcome part, certainly.
Rob reacts bad to bites & I did ask before we committed to leaving England, whether he could cope with the irritation, blisters & pain. His answer, simple, due to the fact that we're here. So, where possible, we avoid being out when the mozzies are & hunt them down inside. The rest of the time, we itch & scratch, popping antihistamínico when things are really bad.
Like the time Rob's hand swelled-up when we were in Sanlúcar de Barrameda.
We nearly went to the hospital, but decided to show a local pharmacist first. She was very matter-of-fact when seeing his hand & didn't seem unduely concerned as she issued some topical cream & a dedicated antihisto. So we decided to give them a try & Rob saw & felt a big improvement very quickly.
We've found Fenistil to be a good gel to apply topically to a bite as it relieves the itch very quickly.
Other times, Rob's bites blister & if there's a few close together, they merge - nasty. The rest of the time, the rash extends in a wide area.
So we do spend time trying to erradicate any flying critter that might be a mosquito. Moths are safe & so are the long legged spiders lurking in their lose webs in each corner of each room. Hopefully they catch & eat mozzies.
This house doesn't have insect screens, so although we do close the windows in the day to keep out the heat, the cooler night air is welcome. We bought some do-it-yourself kits of sticky-back velcro & fine net & attempted to fix this on the outside of the window so we could close the windows from inside. It was a fiddly job, so we resorted to sticking it to the inside & going out to close/open the windows. Not a problem when we live half our lives out under the shady terrace.
There's a multi-coloured tape fly curtain up at the front door, bought before we set-off to keep Woody from flying out, so where do the mozzies get in? & how do they get in your undies to bite under a tight waistband or bra strap? & why do you only feel them as they fly-off after enjoying a bloody snack?
The fly curtain's been great BTW, it's been up at every house, pulled down by the dogs, tangled around in the wind, stood on, trapped in the door, yanked as it caught a sweaty body when we walked through & not one tape has snapped or pulled away from the top rod.
