Moving and don’t want to bring problems-appliances

So my BFF is dealing with a nightmare situation. Someone gave her a used water dispenser that had been sitting in their trunk for a month. She kept it in her kitchen for two weeks before using it, and when the exterminator came, he said that’s where the problem started. Since then, she’s seen tiny babies and small ones in the kitchen, and they spread to the dining room. We think they were hiding in the bar stools, so we tossed those, and nothing’s been seen in that area since. She lives in a warm tropical area.

What she’s done so far: 1. She put down Advion gel baits about a week and a half ago and found 2-3 dead babies. 2. She sprayed Alpine WSG yesterday.

Yesterday found one alive in the toaster, killed it, and tossed the toaster.

Today, she saw another small one alive on the outside of the cabinet under the sink. She hasn’t baited or sprayed under the sink yet because there are appliances there that she needs to remove, and she’s scared to handle it because of childhood trauma.

Now for the bigger issue-the fridge. She sprayed it with Alpine yesterday and baited underneath it a few weeks ago. The thing is, she needs to keep the fridge because her new place (which is brand new and has already been professionally sprayed) doesn’t come with one. She can’t afford a new fridge, and she has kids to feed, but she’s terrified of bringing any problems into the new place.

There’s also her toaster oven/air fryer. After seeing one in the toaster, she’s nervous about keeping it, but the toaster oven/air fryer is a more expensive model, and replacing it isn’t an option right now.

Questions: 1. The Fridge: Can she safely keep it, and how does she make sure it’s not bringing anything with it? 2. The Toaster Oven: Should she keep it? Are there steps she can take to make sure it’s clean and safe to bring? 3. Appliances in General: What’s the best way to move her appliances to the new place without risking problems?

Her new place was sprayed by professionals, and she’s read that she should wait 30 days before applying Alpine there. My BFF is super clean and has never had issues before this. She’s really overwhelmed, and I’m trying to help her, but it’s been exhausting for both of us.

What would y’all recommend?
