Bad isopod and pond snails

So I found what I am certain is a bad isopod of some sort (couldn't get a good pic but it's huge! About 1/4 inch) and I have discovered little pond snails. Argh, I was planning a rescape next week anyway.

Question : should I replace the substrate? There are no fish yet and I'm only a few weeks into the cycle so it's not totally terrible.
I plan to dip my plants to be sure everything is gone.

Hard to kill things in the substrate, but there is one way:
Baking.
Put the substrate in a pan and dampen the substrate pretty well.
Bake it (250*F or about 125*C, temperature is not critical) until it is dry.
The boiling of the water, the steam, will kill a lot of things.

This REALLY STINKS! If there is ANY way of doing it outside (Bar-B-Que?) Do it.

You could try solarizing it, too. This means to put it in a low, wide box that has a glass lid, and is well sealed. Spread out the substrate so it is as thin as possible. Aim the glass lid at the sun. The sun, shining through the glass lid will heat the substrate enough to kill a lot of things, but maybe not everything.

Another option: Whatever you dip the plants in you might soak the substrate in, if you know that you can absolutely get the sterilant out of the substrate before putting it in the tank.

If you have one of the high CEC substrates this is tricky. I do not know all the materials these soils attract.
If you are using a sand or gravel that is easier: I would just soak these in bleach, then rinse with a double dose of dechlor. Air/sun dry to remove the rest of the chlorine.

thanks again Diana for your help. My substrate is miracle gro organic garden soil topped with sand. I may use the oven/bbq or bleach. How long would it be in the oven for do you think? I can always open up all the windows and doors and sit in the backyard for a while lol. Either that or I may just replace the substrate, I still have half a bag of each of them sitting in my garage

Much easier to replace the substrate, and you are sure all the nasties are gone.

Baking time might be about half an hour. Time to air out the house a lot longer. BIG fans would help.

I think I will just replace it.
Knowing my luck and the space in the house, one of the dogs or cat would decide to dig in the air drying dirt (like they did to my planters, little buggers lol)

Good news i think it's a scud, but I still don't want it since I have no fish to keep them in check.
