Instead, release them at dusk or early morning. Before releasing, spray a fine mist of water on plants that have aphids on them and place the ladybugs at the base of the plants. Do not release ladybugs on plants that have been sprayed with insecticides as the chemical residues may kill them. Be prepared for ladybugs to fly away in a few days as they typically don't lay eggs on the plants they have been released on. When you see ladybugs, remember that they are considered lucky in many cultures, for various reasons.

Asian lady beetles also have larger white "cheek" markings and have more white on their heads overall.
A sure way to tell the difference between an Asian lady beetle and a ladybug is look at the spot where the head meets the wings. If the bug in question has a black 'M' marking in that spot, that's a telltale sign you're dealing with an invasive species. Asian lady beetle shell color can range from light orange to bright red, so most will have a similar color to a ladybug. Asian lady beetles are known to sneak into your home through cracks or holes when it gets cold outside, which ladybugs won't do.
Light attracts the pests so they'll often congregate on siding on the south side of building, around door frames, and in windows. They may bite by scraping the skin they land on, which feels like a pinprick but won't cause any real damage.
When threatened, Asian lady beetles release a stinky yellow that can stain surfaces and trigger allergic reactions. While it's very rare, Asian lady beetles can infest dogs' mouths. If a dog happens to snap up some beetles, the insects may attach themselves to the roof of your pet's mouth. This won't always mean a trip to the emergency vet, though the beetles will usually need to be pried off. If swallowed, the insects can irritate a dog's gastrointestinal tract and in extreme cases, can be fatal, so make sure to keep your pets away from Asian lady beetles and check their mouths periodically.
The best way to keep Asian lady beetles out of your home is by sealing and patching potential entrance points. Hang it in your garden so the ladybugs have a warm, dry place to spend cooler nights. They may even use it for their winter hibernation, ensuring that our favorite beetles will be back again next year.
How about a ladybug feeder? Thread a piece of twine through it and knot the ends to create a hanger. A couple of raisins or crumbs of cheese will help keep the ladybugs happy when the aphids are in short supply.
