Ladybugs are indeed the prettiest little bugs that we see. While most may want to attract them into their garden simply to make it look a little prettier, these little bugs can prove to be quite useful to the garden they call home.
When you see larvae that look like they could belong to aphids, just leave them alone. Resist the temptation to bring out the exterminator and take them out. Aphids are one of the things that ladybugs absolutely love to eat. So the more aphids you leave within your garden, the more chances you have of ladybugs entering your garden.
One of the sure shot ways to attract a bug, or a human being is to provide the right kind of food that he or she likes. Amazingly, it is the same with these pretty bugs. Just keep some delicious foods that they like in your garden and see them swarming into it, to satiate their hunger.
Keep the Garden Wet
Ladybugs thrive in wet areas. They absolutely love moisture. They're hungry little bugs who eat and drink voraciously and are drawn to moist areas that provide them with these conditions. So, to attract them, you need to keep your garden and all the plants in it suitably hydrated all the time.
If even after all these, you are not successful in attracting ladybugs into your garden, you have one last choice. Call your local nursery and see if they have a stock. Buy some of them and keep them in your garden. They'll certainly attract their friends and family into your garden! Good luck!
