Gday Rick you don't say how old your van is but I suspect the screens may not have been fitted properly and the dealer will either fix them or possibly advise you of a fix and if none of that works try some surface spray that will kill the bugs.

We have a auto dispensing insect spray in the van. We had a problem with sinapore ants. Had the pest control guy do the site and van but they soon returned. These little buggers like to eat plastic along with wire insulation etc. After fitting the despencer we have had no problems with any insects. The wife is sensitive to the ordours of most sprays but these units only meter out a small amount. Needs a refill about every month.
cheers

We use one too, very good at their job and as you say, very little odour.

Rickp , it sounds like you really have to take the van back to the dealers. Surely this would be covered under warranty, the insect screens are not supposed to let insects in around the sides!
At this stage I don't want to say the brand of the van as I want to give them a chance to fix it and I don't want to jeopardize any dealings with them.
I know they have removed a negative comment from their facebook page so I will wait and see what their response is.
