I have a pine tree growing next to the main door of my house. There is a hive of stinging insects (bees / wasps) nesting inside the pine needles, I am considering whether to leave them alone or to get rid of them using a wasp spray.
A family member has been stung once. Watering the tree with a garden hose ruffles the pine needles enough to set them off.
My location is in Malaysia (equatorial Asia), the insects are about 1.5cm to 2cm long, the hive is about eye level off the ground. The insects has 4 yellow stripes across its abdomen.
