I can comment on the bug spray to explain how that works. We made personal kits for each of the security people in Huntsville and Toronto.
For the Huntsville kit, we had the contractor company provide a high-end bug spray. As you can imagine, if you're standing for 12 hours in the bush in June, you're going to be in bad shape. We had to get the best bug spray we could. We had to have a high-quality sunblock. We had to have wet wipes, the ones you tear out. The whole package, with the bag it came in and everything, was approximately $40 per person. There was also a medication in there. In case you were bitten by the bugs, you could apply it to reduce the swelling and the itch.
In the Toronto kit, we eliminated the bug spray and the itch medication.
