Ok, I'm going to try to reply to a few of you...If I miss anyone...I do want to thank you for your contribution on this thread. I appreciate it when discussions are made in the manner most of this thread was...
montezuma --- My 2 cents worth may save you more in the long run... stop buying from middlemen when it comes to your feeders! Buy from a grower and try to find a reliable one that is closer to you, not from someone 2000 miles away and in an entirely different ecosystem! Also, never purchase more than you will feed in 2 weeks unless you have the capabilities to maintain them. BTW, waxies tend to die off when you change their temperatures drastically (such as the 36 degrees or so in the fridge to the 73 room temp!)
I know better then to buy from a middleman. I guess I just wasn't thinking about what type of company LLL really was (not "bad guy" - but as you said, "middleman"). I saw an ad on Kingsnake.com and ordered.
I have a wonderful cricket supplier that automatically sends my supply every 2 weeks (
www.qualitycrickets.com). ANY problem I have with my order...They'll take care of it. My very first order I had 1,000 1/4" crickets die on me for no apparant reason one week after I ordered. I didn't expect them to send me a new supply, I just wanted to know if maybe something I did caused the smalls to die and how to correct it...but they DID send me a replacement 1,000, without me asking. I wish they did worms!
I've never purchased this many waxies at one time, I knew though they would be fed off within two weeks though. Thanks for the information on the sharp temperature change. I hadn't thought of that! It would make sense then why I had a few die within that 10 hour period.
KelliH -- These kinds of things happen in the summer months with feeder bugs. As far as leaving waxies out at room temps, I do it everytime I order them, however I do not leave them in the cup, I dump them into a larger container (shoebox for instance), then pick out ALL the dead ones. I leave them at room temps (74ish) and mine are always fine for the entire week I have them. Now if they are left sitting in a small deli cup all crammed together for several days at room temp of course many of them will die, and attract "crap" flies, which lay eggs that hatch into maggots (eww).
I buy my feeders from reptilefood.com now, and they have always arrived live (they are sent UPS Next Day Air). Now I have found a few spiders in the crickets before, which grosses me out, but I haven't had any real problems with their worms. Grubco is another company I have ordered from in the past, and anytime there was any type of issue they always sent me replacements.
See, that's what confuses me. I'm told that because I left the cup out for 1/2 day that's why I ended up with maggots. Then you say that you do leave you're waxies out for a week without a problem (and I've also had experience with this). I guess in the end no one will ever know exactly WHY they ended up in there (though I think the theory on eggs being laid during shipping is a logical one).
Also, thanks for the recommendations on the suppliers. I will have to test them out. What type of bedding/feed do you use for your waxies you keep?
Dragondad -- Your waxies are nothing but the laval stage of a beatle (not John, Paul, George and Ringo). The difference is the label that society has put on the term maggot. I would loose my job if confused flour beatles were in my plant, yet many feeder dealers will sell them too you......
The maggots or at least the eggs came with the waxies. Even in fly season, even in warm temps you would not see the larvae generate in 10 hours, no way. The 24 hours is from the time the egg is laid to produce at optimum conditions. So whoever supplied LLL has a fly problem contained by the refrigeration of the waxies.
Waxies are the larval stage of a moth.

Thank you for the additional information on fly cycles. I didn't think it could have happened here within that short amount of time!
I also have been informed that LLL is supplied by Tophat Cricket Farm.
BLUEBEASTREPTIL -- As others have said, it seems we're getting off topic with this thread. It's one thing to have a major loss of a large insect order that they didn't want to replace, but to lose out on $14 worth of waxworms and make a thread about it is kinda shady... In your first post, you said you got them "a week or so ago." Even if the flies didn't get in there yesterday, you've had them a week, and have assumingly been using them during that time. I would think it's also safe to assume they've been left out during that week, whether it was 5 minutes or 10 hours. So if you figure you've paid $14 (half of which should be called shipping), used them for a week and now have an issue that I thought LLL was reasonable in explaining, you're really not losing out on anything.
As I've said from the beginning...I used about half of them the day I received them...Put them in the fridge...The other day I pulled them out, set them on a table in my reptile room...Forgot about them until I got home 10-12 hours later...Then SURPRISE...MAGGOTS! I could have purchased from a local store, paid $4 for a tub of 50 and used them up rather quickly. I understand that accidents happen...but LLL is saying "I'm not sure what they are...but I'm sure they'll be safe" when they really don't know. They're insisting that their supplier couldn't possibly have infested waxworms...When they really don't know...I don't know...Maybe I'm reading into LLL statements too much.
