I find the noise calming .. you sleep with the window open  ?

Do you have cats in the area? Since I have a cat at home, no longer hear frogs as they are being chased .

need to check the drains as well , maybe there's shrubs or light source that attracts insects and hence attract the frog .

berudu (offspring of frog) will live in drain that have water , to avoid this , need your drain to be either flowing fast or completely empty (no water). need to check if there is anything blocking your drains .

its a collective issue  , so best bet is to discuss with your neighbour .

Question 1 ... Is the frog on public area?

Question 2 ... Is your neighbor also trying to get rid of the frogs?

Be honest cause my solution will cause neighbor to react very differently if they are frog friendly.

buy a bottle of cheap vinegar (those that isn't for consumption) put them on spray, then spray the side of the wall or place that frog use to hang out especially non moving puddle .... it will take sometime and you have to spray those spots for like two weeks ... useless to spray on moving water, but usually frog touch side wall or camp at place with a puddle. What it does is the moist wet spot that has vinegar will burn their skin so they won't be comfortable staying at that spot. And 2nd it will affect their tadpole causing them to become smaller and smaller to the point that they are no bigger then the size of a pea.

The slightly unfortunate part is because you share longkang with others so even if your spot is clean or your neighbour spot is clean the next few section down the line the frog can still migrate there and you may have less noise but there will still be noise ........ unless you go buy a few bottle and spray the whole line.

Reason why I know is because my place got pond and raining season always can hear a lot of them singing ..... a kampung friend teach me how to deal with them.

I wouldn't say it's an absolution solution cause it's still depend on your Surroundings. If your long Kang easy flood with heavy rain water and get wash frequently then it's a little bit harder to get rid of them as long as the spray area is constantly getting wash.

But if it's around your house especially puddles or spots that allow your vinegar to sit it's pretty much sure that at least 3 generations of frog won't be around. I always do it when raining season is coming. Roughly once a year.

Artificial Vinegar from jaya grocer, brand prob yeo's. 99 mart also got. When I started I spray everyday for two weeks to make sure they don't come back, then after a long while I just spray at place that they might be around like twice a week for two weeks if I hear them outside, this days I just spray once when I know raining season is coming and only twice for a week then I hear no sound until next year raining season.
