OK, bug lady has to chime in here. Sorry folks, but those who have known me for a few years from other places in cyber space know that I am a bit picky when it comes to certain things and that includes non-native species of plants and animals/insects that cause harm to indigenous species. Before I go further I have to say this is not a rant and I am not looking to get any sort of crazy dialog/banter going. OK, that said...
The ladybugs/beetles (they are beetles) that are sold in garden centers are usually multicolored Asian lady beetle (MALB),
Harmonia axyridis. For many of you in the north, you know them as the ones that invade your home as fall approaches, have a rather sickening smell when en masse and have actually been known to bite (yes, folks, the sweet little ladybug, no, I am not making this up). They are extremely disruptive to some native ladybug populations and have also been known to feed on early instar monarch butterfly caterpillars.

Believe me, your occasional outbreaks of mites are not enough for them to stick around & they will never be able to complete their life cycle in your home. It is the larval stage that has the biggest appetite. More importantly they are toxic to chameleons – remember that whole
black/red/orange rule?
Btw, ladybugs are generally sold to control aphids ans scale insects. Here is a link about
MALB
