bug can be classified into two ecumenical category : bugs that eat plant and bug that eat other bugs . While it would seem that let no bugs in a garden is a good thing , this is n’t needfully so . We ask some bugs in the garden to pollinate plants and others to break down plant debris so those resource can work their way back into the soil equating .
A lack of healthy predators leaves a garden unfastened to the intrusion of a pestiferous species . In fact , the best aegis against pest eruption is have a preestablished occupant bug population .
For a gardener , it ’s crucial to know a bit about germ so as to realise which creepy crawlies are helping your garden and should be promote , and which harmful creatures are unwanted and should be discouraged .
Spiders , for example , have an undeserved repute . These active hunters excrete many of the harmful louse that appear in garden , but nevertheless , hoi polloi unremarkably kill spiders whenever they encounter them . butterfly , on the other hired man , are considered lovely , fantastic creatures , but in actuality , the eggs of butterflies often contain insatiable plant feeder like chou loopers and tomato hornworms .
So , yes : Bugs are both good and bad , but even the sorry ones are n’t usually a persistent pain in the neck or a literal danger to the garden . nurseryman can determine how to roll with the poke and surf the ever - changing waves of different bugs that seem in their gardens by understanding when to remain calm and when to take military action . A calm and educated nurseryman is a honest surfboarder .
The Rogue ’s GalleryStrictly verbalize , “ hemipterous insect ” are solely member of the louse order Hemiptera . However , in the circumstance of this article , any crawling , flying or wriggling creature will be anticipate a “ hemipteran . ”

Centipedes and MillipedesThese two bugs appear similar because both have a lot of legs , but it ’s easy to distinguish the round - bodied millipedes from the matte - bodied centipedes . Millipedes , the pear-shaped ones , are slow movers and eat mostly decaying plant materials ; however , sometimes they munch on young seedlings . milliped are such slow toady that picking them up and confuse them by from a bed of seedlings is believably the best eradication scheme for gardeners . Millipedes wo n’t bite , but they might stink a bit ; when threatened or handled , they emit a musky smell that can stay put on a person ’s hands for a few minutes .
centipede are flat , truehearted movers and tireless hunters of plant vulture ; they do n’t have the wonderment or thanks that they deserve . Everybody seems to call up the National Geographic article about the big , poisonous centipedes in Asia , but they do n’t understand that centipedes are unambiguously effective for gardens . These fawn hunters fertilize on all form of other bugs in the garden . As long as you keep them out of your menage , there should n’t be any problems with these creepy - looking creatures .
Flying StingersFlying insects with stingers are some of our least dearie ; we tolerate bees because they pollenate our plants . They can sting if backed into a recession or sat upon , but they do a caboodle of good in gardens ; any farmer is golden to have these fauna among their crop .
In addition to the European Honey bee , our gardens can be visited by a variety of other bees . Native bees , both societal , like bumblebees , and solitary , like A. E. W. Mason bee , are still reasonably plenteous in garden that offer a wide range of flowering plants . The one species that amends plants , the leaf - cutter bee , is not very destructive and not worth the battle .
The stars of the stinging class are the predatory wasp . These hunters feed upon a chain of mountains of garden pests , usually attacking grubs and larvae . Some of these colorful wasp do n’t really even have stinger , like the Trichogramma wasps that assault moth eggs and caterpillar ; Ichneumon WASP that prey on flies and beetles ; and Aphidius wasps that raven on aphids . All of these wasps are so worthful that they ’re among the most often trade beneficial insect . Although there are a growing number of physical retail localization where beneficial insects are sold , the net is the most easily accessible for the majority of people ( see “ Buying Bugs ” on page 72 for some online resources ) .
Hover fly , which are n’t actually related to bees or WASP , count like a bee , and are identifiable by their replicate bobbing and hovering . These are worthful bugs to have in the garden because the adults are active pollinator and the larvae seek out aphid .
worm : Green , Brown and InvisibleIn worm talk , green think bad . All of the dark-green dirt ball that creep on plant are unfit intelligence . Cabbage insect , inchworm and the Brobdingnagian tomato hornworms are well - known insect pest . These segmented worm are telling eater ; whole plants can be strip in just a few days . Twelve of these hungry creature , or their more colorful caterpillar cousins , can pass over out a whole dustup of boodle or tomatoes . heedful gardeners know when worms appear in their garden and often treat them using beneficial bacterium such as Bacillus thuringensis ( Bt ) , promptly available at greenhouse .
Earthworms are always good , but the most numerous worms in the soil are the bantam , barely seeable nematodes . Nematodes come in two grade : The more numerous case are predatory on animals , while the other mintage onrush works by burrow into roots . While a nurseryman does n’t see roundworm , one can much sense their presence in grime that is rich with good texture . It ’s a near thought to keep ground nematode population healthy and happy , as they themselves allow for the sound shelter against pestiferous nematode outbreaks . you could do this by reducing your use of pesticide and keeping the organic cabal high .
