When I was in college I spent a few weeks in the Amazon rainforest in Ecuador in a cabin study and collecting stuff.
I brought along the super powerful 99% DEET. Everyone else had that crappy pleb camping tier bug repellent that was only like 3-10% DEET.
All my friends got eaten alive by bugs but I was sitting happy. They begged me to share, but I only had enough to last me for the trip.
I swear, DEET is the best stuff.
The only downside was when I put it directly on my skin it blocked my sweat pores and stopped me from sweating, so I would get heatstroke if I wasn't pouring water on me throughout the day. Also that stuff was so strong it melted the plastic of whatever it touched.
It was much better than literally being covered in bugs all day.
