Does reptile relief kill the eggs?

I was poking around the internet and came across Reptile Relief. (Kills mite on contact) but does that include the eggs? I lost some snakes a few years ago while on vacation because of mites. I think this might be good just to have onhand, just incase. Just curious if it kills the eggs on contact or is a retreat needed

I've never used the product, but the sales blurb says

The active ingredients in De Flea products work together to soften the waxy exoskeleton of fleas, ticks, lice, mites, and other insects. Once the insect's armor has been penetrated, its internal organs are saturated and the insect quickly bursts. De Flea products work for all stages of an insect's life cycle, eggs, larvae, pupae and adult--effectively eliminating all insects from the home

I generally take those things with a grain of salt until I have first hand experience, or hear enough positive feedback to make it believable.

All this junk does is make things smell like an orange.
It's worthless IME.
Pick up a can of provent a mite.

I use the Nix Mite Treatment method. All of those chain store mite treatments are junk in my experience.

The key with treating with the reptile relief is you have to actually saturate the mite or egg. If you have a lot of tanks, or it get's out of control before you realize it, it's hard to cover every surface, and that includes woodwork, carpet, curtains. And you don't want to kill your reptile so you have to be careful.
If you find you've got them, remove the snake or lizard, soak in a bucket, use a toothebrush to rub off any you can see, rinse, if it's infested, you may want to use an antiseptic like povidone from a pharmacy, dilute to a weak tea color, dry, spray with reptile relief or any other reptile safe spray but not in eyes, put in a shoebox.
Leave it there while treating the reptiles room. Wash tank and supplies in hot soapy water, soak in a 10%bleach, water solution, rinse well. Dry and then soak well with reptile relief. Let dry. Put branches outside to sun dry for the day.
If you have a rug and furniture in that room, use flea powder to dust the rug, couch mattress, etc. But remove curtains, sheets and wash. Let flea powder stay on for the day. If you have wood frames or a wood tank stand, use furniture polish and soak. It sounds like a lot, but a few hours of work once a week for a few weeks is worth it rather than losing your reptiles.
You have to vacuum fleapowder off floor and furniture before bringing reptile back in room. Use newspaper in tank instead of substrate and don't put any wood ornaments in it for a few weeks. I think it's hard to find all the eggs so you should be prepared for a new generation a couple days later and a repeat cleaning of the tank and spraying it again should help till they die off.

If they don't work, try googling the topic.
Good luck!

If you can still find some Black Knight, it works quite well. That along with the Nix treatment mentioned above^^
