We do the tarp thing and don't have an issue with bugs too much. Flies are only bad in the middle of summer or if you leave food lying around. We find middle summer camping too hot for us anyway. Sand midges and mozzies are only bad after a lot of rain or in coastal creek areas. It doesn't rain much in QLD & we don't camp near saltwater creeks
We really only have a bug problem after lots of rain and only at night when the lights get turned on - hence why i don't run fluoros as they are a magnet.
We have this setup:
I have 2x small bunnings GMC tool bags, one with metal and sand pegs & light holders & 2 mallets. The other bag holds the ropes & springs. I have an army style duffle bag with 10x aluminum & 4 galvanised 3-piece tri-poles (tri-poles are way smaller). And i lay the tarp and the 2x (4 pieces) largish ridge poles on my drifta kitchen under the tonneau. I have adopted this style & setup and the smaller aluminium poles because up until we had bub we had to pack everything into the back of the wrangler and there ain't much room back there
When setup, it uses 6 aluminum poles on the short ends of the tarp (leaving 4 poles spare incase) and the 4 galvanised poles go in the middle on the long length of the tarp to hold up the ridge poles. I use the galvanised steel poles with the ridge poles because the allum ones aren't as strong.
I use 14 pegs & springs and 10 individual ropes. As you can see in the pic the corner ropes are one piece.
Once setup, it stays there. Wind will not knock it down and unless it's cyclonic, not even very heavy rain will not wet anything underneath. It also allows a nice breexe through without any flapping at all. Dew is no match for this setup
The one in the pic is a 16'x12' but i had a 16'x24' but it was too long. I will probably try to get a 16'x16' or 16'x18' when this tarp wears out as my ridge poles can reach 16' wide.
