You can use a systemic granule, like Bonide for houseplants to kill bugs in the soil and on the plant. Just give it a couple of days to distribute throughout the plant before allowing the plant to be near any that you have inside the house.

I do not take houseplants outside for that very reason. I know some like to do so, because the plants grow like crazy. But at that point, they’re really not houseplants, are they? And it’s a lot of work to clean them up and bring them in. I guess it’s all in what you like to do.

Houseplants in the house all year long, I consider indoor gardening and it’s rewarding. And beautiful!

I inspect for anything large or harmful on the plant or the soil but otherwise, I don't bother. I have found.......over decades of doing this.......that very few insects hitch a ride indoors and if they do, they will eventually die off on their own. Baby snails are typically the primary culprit I encounter and they can be hard to find. Soil dwelling insects I seldom bother with.......they stay in the soil or if prompted out of the soil, are easily dispatched.

There is virtually NO concern that they will find their way into your ear or nose while you are sleeping!! (unless either of those orifices are filled with potting soil :-)) I think you are fretting about this unnecessarily.

I heavily spray plants and soil with Bayer 3 in 1 insect disease and mite control multiple times before coming in.

Most of the pests I deal with are so small they can easily make their way through a window screen.

So keeping them indoor all year would probably bring the same issues there would just be no predators to keep them levels in check.

If the thought of bringing plants/soil sprayed with 'cides inside is equally concerning, dunking plants in a tub of water so the soil is submerged for 10-15 mins should kill anything that needs to breathe. I do this to pots that may or definitely do have ants trying to make their home in one of my pots.

Another option, if using a plastic pot that roots can slide out of easily and remain in the pot shape is to take the plant out of its' pot, put it somewhere up off of the ground overnight, and likely anything living in there may want to leave. This works with ants most of the times I've tried it.

Another option could be to repot plants before bringing them in, remove the old soil and replace with new, then bring it inside before sitting it on the ground. Sitting on the ground is the most likely way for critters like those you described to get into pots. Using pot feet or other kind of riser that keeps the bottom of the pot dry and off of the ground can help prevent pots being as enticing of a place for them to go.

One thing to consider is that if there are particles in your pots that have reached the level of decomposition to where critters are able to find enough to eat to sustain themselves, the soil will quickly turn to mud (critter poo) in the bottom of the pot, which will cause roots to be unable to access enough oxygen, leading to suffocation/rotting. If this process starts to happen, munchers of decaying organic matter will start munching the decaying plant roots, and if there is nothing left but plant roots to munch, healthy or otherwise, that is what they will do. If you notice a pot is a lot heavier when you water it than right after you had last repotted, this can be the cause. Outside pots also accumulate grit/sand when the wind blows, that can sift down to the bottom of a pot and cause the same problem over time.

Thanks I will try those options but even if it doesn't work it probably won't be a big deal as Gardengal said. I think I am in fact a little too paranoid about this lol. I can't spray anymore. The plants I'm bringing in are citruses and they are severely stressed from the recent sprayings I've applied on them. Leaved turned all yellow and started dropping. Anyway I went off topic but guess I'll either have to hose it off with water or inspect each leaf one by one. My actual houseplants which I recently purchased and potted up stayed inside this whole time and those were the ones I'm talking about that had a centipede and all sorts of soil dwelling insects in it. So coming from outdoors to indoors must be even worse...
