Only saw a couple of wasps last week (6th-13th August) and one of the giant black things Aly mentioned so no great problem.
Plenty of biting mozzies
during the day as well as at night and I collected about ten bites through the week, despite using Boots After Sun with repellant, Jungle Formula Tropical, eating Marmite and drinking alcohol
Roy doesn't worry much and uses anything he can lay his hands on (when he remembers) and was only bitten twice!
To relieve the itching I used "Irriderm Gel" purchased at Inas. Whenever we sat on our balcony - day or night - we had a Boots mosquito coil on the go which was brilliant.
We had the room door open all day every day, but closed it at night before we went out and gave the room a really good spray with a local flying insect deterrent. No problems through the night.
