supona is an easily found poison...... you spray it outside with a
bombita, ie shoulder carried crop sprayer.
It kills everything. Flies, ticks, cienpies, ...... more or less every insect.
It also settles on the ground, so has some lasting effect.
Upside : does not affect plants ( well ornemental plants that is, i wouldnt spray my fruit and veg with it...... even though locals do ).
........locals even use it inside !! On their clothes and all, to kill off creepy crawlies..... but thats a big no-no for me.
Also very cheap.
Downside : very nocive poison. I do it myself. I dont trust any1 not to get it allover dog water bowls, swimming pool, tools......etc.
I use supona maybe once a year, unless a specific problem. That combined with coils, sprays and mesh on windows/ doors, makes for not-too-many mosquitoes.
P.S. i am not an anti-mosquito-spray-on-oneself kind of guy. I dont trust those bloody things to be safe.
