New Skeeter Trap Not Working

I started a thread a few days back about my mosquito problem and bought a unit called SkeeterVac SV3100 to combat the situation. From the video on the website and from some reviews I'd read it seemed to be the answer to the problem. I got it yesterday and put it together, attached the propane tank and got it going by 5:30 pm. I let it run all night and all day today checking it when I got home today which was about 24 hours later. Not one damn mosquito in that tray. There were several unidentified bugs and some gnats but no mosquitoes. I was hacked to say the least.
I got on the Internet and talked with a rep about it and was told I had the scent door for lack of a better word, open too far. I told her it was opened about half way since the instructions didn't tell you how to set it and was told to only open it 1/4th the way. So, I went out and closed the little door to about 1/4 and checked again a couple hours later at about 6:30 when they're really bad...nothing. My dog came out to investigate and sit about 15-20 feet away and I looked over at him a few minutes later and they were all over him. Talk about pissed. Here's this nearly $400 unit sitting there running and they attack my dog 15 feet away. I am not a happy camper. I hate it when things don't work as advertised and if things don't pick up I may move it some place else. If that don't work it's going back.

I was expecting to see at least 50-100 in that tray when I got home today but no dice. I don't know. If it doesn't yield something by later tomorrow afternoon I may move it but to me where it is now is a pristine place. Most discouraging nevertheless.

It has been, Al. I expected it to work as I viewed on the online video where the guy shows the tray with a couple hundred mosquitoes after the unit was on and running for one day...I had zero. There's plenty of them around here as that's the reason I bought it so, not sure what's going on. They seem to want my dog more than be lured to the unit.

The instructions said to put it in the shade upwind of their travel. I don't know how I'm suppose to know where they bed down but I put it in the far end of the backyard close to the shed where I've seen them on my dog a lot and used the Lurex attractant, as they call it, rather than the other kind that comes with the unit since most all, if not all indeed, the mosquitoes I've seen and caught have been the Tiger mosquito. The Lurex3 as it's termed, is solely for that breed but as I checked the units trap out this morning about 9:30 there is still none in the trap.
From all I've read this breed doesn't mind sunlight as long as it's not direct. I've seen them chase Bubba from shade to sunlight. Their not your typical mosquito and are most aggressive and out all day but not at night. We have China and/or Japan to thank for these varmints as they came over in old tires bound for recycle from what I read. Well, either way they're here and I'm waging total war on them.
That photo cortez posted is exactly what they look like.

I don't think it kills spiders. At least I haven't seen any evidence of that. If spiders eat mosquitoes they're sure doing a poor job around here and I aim to fire every one of them.

Maybe that's what I should have done early on-Call a pest control company and have them spray every few weeks or so as this thing's still not producing...most aggravating.

It seems the unit is operating as designed. I've talked with two different manufacturing reps today and another source yesterday and they went through the entire process of setting up with me although the instructions were clear in that respect. What the instructions don't tell you is to not turn the propane on till the knob stops. I was told that was too much and could have overheated the regulator. They told me to only turn the know one turn. Why that couldn't have been in the instruction manual is a mystery. I had to purge the unit but disconnecting the line from the unit to the tank, push in and hold the control valve for 30 seconds and then reconnect and this time only one turn on the tank. I did that all to no avail. After some hours nothing changed as for catching anything.
Another part of the instructions that was missing was about how far open to adjust the door to the attractant which in my case is the Lurex bait since the Tiger mosquito is so prevalent down south and that's what's biting me and my dog. Nothing in the units instructions or with the bait or lure tells you about how far the door should be open I tried one fourth, one half and neither worked. I tried both for some hours and I still hadn't attracted any mosquitoes. There is a tack strip that fits around the unit about a foot high but all it's caught has been several flies and gnats along with pine needles...no mosquitoes. The lure is wrapped in a rubberized sleeve so I guess that's suppose to keep it from drying out and you have to peel it off and then place it in the unit.
This is a pic of the unit. The black and white area is the tacky strip that fits around the unit. Mosquitoes are suppose to be sucked in and found in the clear tray above the strip but to date nothing other than gnats and some unidentified insects have been all I've caught. Meanwhile, I feel I'm just wasting propane.

The 3-pack of lures weren't that expensive. I may try another tomorrow but they were all together in one box so, I don' know it that will help or not but worth a try. They do give a one year warranty but better yet there's a 30 day no questions asked if you want to return it for a full refund. I hate doing that as I didn't buy it to have to ship it back. I bought it to get rid of mosquitoes and planned on keeping it.
I even switched bait or lure this evening(Octenel I think it's called rather than the Lurex) hoping maybe they would be more attracted to that. I'll check tomorrow on that. If not, I'll try using another one of the lures that came in the three pack. Not much to lose at this point.
