We all would like to use natural or organic means to do pest control. One of the hard sells we are often approached with is using Lady Bugs instead of chemicals for aphid control.
Will Lady Bugs actually control my garden pests or is it a rip off?
Lady Bugs or also known as Lady Beetles or even Ladybird Beetles and sometimes spelled Ladybugs are a part of a important group of beneficial predator insects that feed on plant damaging insects. These insects include one of the biggest problems, aphids which they can eat as much as fifty per day which can add up to thousands of aphids in their short lifetime. They will also go after other problem insects such as scale, leafhoppers, mealy bug, mites and other problem insects that are soft bodied.
So as a pest control method the theory sounds great. A few things to consider though.
The first is that if you buy a bag of ladybugs online and release them in your garden, it's been proven that a majority will fly off into your neighbors property before settling down. The travel is stressful on this creature and it will take time for them to settle into a new location and call it home. To prevent this it is suggested to net the area so the ladybug can not fly off. This can help so make sure that you get the net with the ladybugs when you buy them.
The second thing is to make sure you are getting indigenous Ladybugs. The multicolored Asian Lady ladybug was introduced in the United States some years ago and proved to be a problem. They were brought in to control aphids on agricultural lands, and subsequently became a pest, driving out native species, wintering over in large numbers inside homes and biting the human residents. They have effectively crowded out the indigenous bugs and took over.
The third item is to make sure you are providing an environment they will stay in. The garden needs to be wet or damp and it is best to release them in the late evening so they will have a cool time to adjust to the new surroundings. There also should be plenty of aphids or whatever pest you are trying to control to feed the.
So the idea is not a rip off, however be sure and see where the insect is coming from, if you have enough pest pressure to make it worth while, and of course, price shop before buying.
Pricing seems to be the cheapest online. The nursery may carry them and they may be fine but actually look at the insects and the environment they are being contained in. If buying locally and they are refrigerated, ask for a warranty that the vast majority are alive. Make sure the net is sufficient to cover the area you are trying to treat and follow the directions in the release procedure.
The rip offs are coming from unscrupulous sellers from outside the country and from people selling them as a must have when you may not even have the pest pressure.
Another alternative many sales people do not mention is you may be able to use your own natural environment and encourage the Ladybugs in your area to propagate and naturally take care of the problem without having to spend that money.
You can attract the locals by supplementing their natural diet with pollen and nectar from flowers like Aster, Sunflower, Alyssum, Cilantro, Carrots, Chives and Yarrow which they will use to nest and hunt from. This can make your garden area more attractive and help encourage a true bio-sphere in your garden that is from the cycle we would find in a real world instead of introducing a predator and hoping it will take directions to attack what we want.
Another thing to consider is where the Lady Bugs come from. There is a lot of talk about bringing in Lady Bugs from the wild or from farmed situation with disease that can harm your natural Lady Bugs in your area.
Some discussion on that subject.
So the answer is you can be ripped off when buying Ladybugs if you do not do the research and make sure you know what you're buying and how to take care of your environment an have a plan on how you are going to proceed.
