Apply April-late summer. Nemalawn Steinernema carpocapsae :. Takes care of sod web worm, cranefly, fleas in your lawn! Apply May-October. Weevilution Heterorhabditis bacteriophora :. This popular weevil-controlling nematode has a particular application time, as it's only effective when applied when daytime soil temperatures reach 12 C. Those application windows are April through mid-May, and then again September through mid-October.
Cold Shots Steinernema kraussei :. Apply it before your first application of weevilution. They start to work once the soil temperature is 6 C. Check in during early March to see if temperatures are right for the first application!
Nemasys Steinernema feltiae :. This is the nematode you want as a soil-drench treatment for both fungus gnat larvae and thrips pupae. It can also be used as a foliar spray to control adult thrips if you're able to keep your plants wet for an extended period of time. How do I order? Click here! Predatory Mites:.
They're a one-time introduction, and will feed on a variety of pest mites, and can be used indoors and outdoors, on conifer hedges, berries, and bamboo, for example.
Stethorus Stethorus punctillum : Stethorus are meant to be used as "hot spot" treatment, alongside the mite predators above. Ready to Order? Aphid Control:. Aphidoletes are a predator midge of aphids. Hype-O Stratiolaelaps scimitus : Hypoaspis are soil mites, and will live in the soil for the life of your plants. No-Thrips Neoseiulus cucumeris : Cucumeris are mites that are applied to the foliage of your plants, and will feed on immature thrips larvae found on the surface of your leaves.
Rove Beetle Dalotia coriaria : Rove Beetles Atheta are generalists that do very well in moister conditions. Wholesale Services. Adult beetles are supplied in packs of At point of sale they are already sexually mature, ready to feed on aphids upon release and also lay eggs in the crop to kick start the next generation of hungry larvae!
The beetles should be released as soon as possible after arrival. Release onto plant foliage near aphid infestations by gently tapping them out of the container. In the event of adverse weather such as extreme heat or high rainfall, they may be stored for several days before release. During storage, adult beetles should be given a top up of honey placed on the inside of the container lid if the original supply has already been consumed.
Spotted ladybird eggs are supplied in packs of or more. These eggs may be divided into several seperate containers to minimise the risk of cannibalism once the larvae emerge. The eggs will hatch in transit or shortly after arrival. We provide a small amount of food sterilised moth eggs for the ladybird larvae to feed on when they emerge, but the longer they remain confined in a container the greater the risk of cannibalism.
Once the eggs have hatched and the tiny black ladybird larvae are visible in the containers it is time to release them — gently tap the contents of each container onto pest-infested plant material.
Further research and development is required to develop ideal release rate guidelines. At this stage we suggest 1 pack of beetles per 20 to 50 m 2 in enclosed situations, and 20 packs per hectare in orchards or field crops. Additional eggs can be purchased to treat any hotspots that have been identified. A note on release rates: Unlike chemicals which generally exhibit a clearly defined dose response curve, with beneficial insects, more is always better.
However, they are costly to produce and the goal should be to achieve the best results at minimal cost. We are constantly trying to strike a balance between cost and efficacy.
There are many factors that should be considered including the value of the crop, the magnitude of the pest population and the activity or otherwise of naturally occurring beneficial species. In most cases our releases are inoculative and we anticipate that our beneficials will establish and breed up within the crop to give long term control. As a general principle, releases of modest numbers is better than a single large release — this reduces risk, improves establishment and accelerates the development of multiple overlapping generations of the beneficial species.
After release, adult beetles should rapidly disperse throughout the treated area. They will begin to consume aphids immediately and start to lay eggs amongst aphid colonies. It may take one to two weeks depending on temperature before their offspring the larvae can be observed feeding on the pest. Regular monitoring is recommended following release to check the beetles are established.
Booster releases may be needed in crops with heavy aphid infestations. Do not expect to see adult beetles readily after release. Note that the larvae look very different to the adult beetles.
Where larvae have been released into pest hotspots it should be possible to observe their development as they clean up the target pest. The larvae will grow and moult several times before pupating and emerging as adult beetles. Practices that reduce wind and dust will help the ladybirds establish.
Avoid releasing beetles where bright lights may attract them away from the release area. In shopping centres and office blocks it is best to release beetles out of hours. Once they develop into the familiar adult beetle, they continue to hunt and kill pests. Ladybugs are good predators and should be encouraged in the garden.
There are about 6, species of ladybugs. For example, Ontario has recorded 80 different species including the nine-spotted ladybug Coccinella novemnotata , the transverse ladybug Coccinella transversoguttata and the two-spotted ladybug Adalia bipunctata. The most common ladybugs being sold are the convergent ladybird Hippodamia convergens , which is native to most of North America and the Asian lady beetle Harmonia axyridis , which is not native in North America.

There are several problems with the collection of wild beetles. The popularity of purchased lady beetles has skyrocketed and nobody knows what this is doing to local populations.
Imagine someone coming into your neighborhood to collect native bees, for shipment across the country. A second problem has to do with parasites and diseases that are local to the collection area , but which might not be present in your location. Transporting these collected ladybugs could be spreading diseases to local populations including rare local species. The convergent ladybug is very competitive, and introducing more into your area may have harmful effects on your local species, some of which are already close to extinction.
As soon as you release the ladybugs they will look for food and take care of any aphids you might have. The remainder were gone within 4 or 5 days. For ladybugs to be effective they need to lay eggs and start the next generation, and therein lies the problem. Field-collected lady beetles are usually in a state known as reproductive diapause.
Their main food source is aphids, so it is important to allow some aphids to live in the garden. Different types of laybugs prefer different types of aphids. Some prefer tree aphids, some like rose aphids, and others prefer crucifer broccoli, cabbage, Brussels sprouts, cauliflower aphids. A diverse variety of plants is always a good idea. Ladybugs also eat pollen and necta r, especially early in the year before aphids have hatched out.
Some species use pollen as a main food source all summer. The same early flowers that are good for bees are good for ladybugs.
