I have changed to repellent made with Picaridin, it is less likely to damage plastics or other equipment than Deet. I only buy the lotion, not the spray. Spray seems to always get sprayed somewhere other than where you want it.

But when the bugs are REALLY bad I dig out a tiny little bottle of Deet (100 percent) that I bought a couple decades ago.
I bought some Permethrin that can be used to treat clothing, last year I sprayed that on two of my jerseys, some hiking boot gaiters (more for tics than mosquitos), a few other things. Seems to help. Bike jerseys that are a knit fabric almost seem to attract mosquitos. I think this is illegal to buy in Canada, but am not sure. This reminds me that I think I need to re-spray those knit jerseys that I sprayed it on last year.

Occasionally use a headnet when the bugs are really bad. I like to wear that with a wide brim hat, the brim holds it further away from my skin.
I have never carried mosquito netting pants or jacket on a bike trip, but I have used it in campsites on kayak and canoe trips. Often only a couple percent of the skin surface area is in contact with the netting pants or jacket, that is the only place that a mosquito can bite you. I wished I had brought this on my bike tour in Everglades and Big Cyprus, lots of bugs there.
