I have a ant problem in my enclosure. Idk where they are coming from and the powder isn't super effective with their numbers. I tried to remove all the substrate but they were back the next day. I don't have any around it and I cleaned the whole thing out so I don't understand where they come from.
One option you could consider is hiring a professional pest control service like https://ajverminatorpestcontrol.com/... They offer various pest control solutions, including ant control, and they have experienced professionals who can help you get rid of those pesky ants once and for all.
In the meantime, you could try using some natural remedies to repel ants. For example, you could use vinegar, cinnamon, or peppermint oil, which are known to have ant-repelling properties. You could also try sealing up any cracks or gaps in your enclosure to prevent them from entering.
