Below is a list of some helpful bugs. These bugs can be attracted to your garden by the plants you choose to grow (more about this in my next blog entry, but if you can’t wait, your local gardening store workers will be sure to know!). They can also be purchased at many gardening stores and online.
* Ladybugs/ Ladybird Beeltes (Coccinellidae): Each one of these wonderful beetles are said to eat as many as 5,000 aphids during their adult life! They also feed on a ton of other soft-bodied insects and their eggs, such as chinch bugs, whiteflies, and mites. Then, the female adults will lay as many as 3-4 dozen eggs each day, which will hatch and consume around 50 aphids a day until they become adults in 21 days. You can't go wrong with that kind of math!
* Crypts (Cryptolaemus Montrouzieri): These beetles are a type of ladybug, that look like your common ladybug, only darker and will help if mealybugs are driving you crazy. A great way to get immediate results is to place the eggs on the infested plant, so that the larvae can feed on the undesirable bugs as soon as possible. Unfortunately, most places only sell them as adults, but they definetly munch on your pests too.
Calvin's blog entry about it!
* Aphid Lions (Green Lacewings Larvae): Aphid lions are veracious feeders of aphids, spider mites, mealybug crawlers, immature whiteflies and caterpillar eggs. If you plan on purchasing them, make sure you are getting them in the egg or larvae stage because they are big bug eaters only in their immature stage. Place them near the insect problem, but you have to be careful not to place too many in a limited area, because they are known to become cannibalistic.
* Predator mites: They are great at controlling spider mites, which can be commonly found indoors as well as in the garden. They are purchased as adults and will eat 1-3 adult mites or up to 6 mite eggs each day! There are many species, so you need to know which type of mites you have, so you know the right type of predator mites to purchase.
* Trichogramma wasps: Last but not least, these are tiny wasps which are parasites of the eggs of more than 200 types of moths and caterpillars. They lay their eggs directly inside the eggs of the pests in your garden, killing the eggs as they hatch. As soon as the wasps mature, they will fly off in search of new eggs to parasitize. An important thing to note about these guys is that there are many different species of Trichogramma wasps and some are more effective against certain pests, so purchase eggs appropriate for the pests. which have invaded your garden.
