We have that same problem here in the US. My husband's sister lives in Mason Texas, and they are absolutely overrun with wild boars.
Yes, Texas is one of the hot spots for this animal in USA (where is non-native). The wild boar is thriving fast in south and mainly in south-east, where predators that could control its expansion were extirpated (basically cougar, jaguar and wolf).
This week I "caught" some interesting ones with the cameras, these fellas would keep your squirrels far from mangoes (also would eat your hens, I'm afraid
).
