it gets rid of pests and its "husband"
The black widow contributes to it's ecosystem in (mainly) the same way that most spider do: by consuming small insects, namely flies and mosquitoes. The black widow also help control pests that affect crops such as locusts, caterpillars, grasshoppers, etc. The black widow can not be safely consumed by birds, since when the birds eat their venom glands they are poisoned. However, black widow spiders are eaten by mud-dauber wasps. Generally, in ecosystems where the black widow spider is not present another species of spider will be present to control the insect population. black widows have red dots on their belly.just a fun little fact. i'm sorry if anything is spelld rong i am just 8.

They eat pests, including other spiders, as mostly all spiders do.
why would you want to? spiders are natural predetures who eat the pests that damage your strawberries and the spiders do you no harm.
Do you want to know something about tiny red spiders? There are many spiders that are red. There are probably many spiders that could be thought of as "tiny red ones." Adult chiggers look a little like spiders. They have eight legs. But they only have one main body part instead of two like spiders. One tiny red spider makes a sheet web. They catch very small insects.
A leaf mantis eats other bugs as an adult. Usually they eat crickets, flies, spiders, and other insects considered pests by humans.
In Rare cases the black widow's and the brown recluse spiders can kill humans but it is extremely rare. Most of the time when bitten by one of these spiders you will be fine, even if you don't go see a doctor, however I highly recommend seeing a doctor immediately. Extremely skinny people and people with high blood pressure are more likely to get severe problems/damage from the bite. However, most of the time you will be fine even without treatment (I still wouldn't risk it however). In reality spiders (kingdom: animal, phylum: Arthropoda (greek for jointed foot/appendage) class: Arachnida, order: Araneae) are our little friends who are a natural pest control (though can be considered pests as well by people with arachnophobia). In other word even though they're creepy as heck, they help us out quite a lot and demand our respect. I'm not saying don't step on spiders or anything(can't say that cause I'm terrified of them and if necessary I will kill them), I'm just saying unless absolutely necessary, leave them alone. Thanks
This is a tough question and the answer is probably not what you are seeking. Black Widows are very private creatures and prefer woodpiles, rock piles, dark and damp environments and do not generally come out to bother people unless provoked and even then, a bite is rare. The chemicals used to kill Black Widow spiders is unknown in consumer world with exception of one product that I have been able to locate: BAYER Total Home Defense. This product contains B-Cyfluthrin, which is said to be able to kill or rid your home of the Widow and Recluse species of spiders. Althought this had not been proven, a quick phone call to several pest control facilites in the area and I've found that B-Cyfluthrin is chemically compounded in several of the pest control mixtures that I've been told work. It is known commercially as several different chemical names, but nonetheless, is still the same. Products such as Ortho MAX and SEVIN insect control, specificly exclude the Widow, Recluse and Scorpions as pests that their product will kill. So, if you want them gone, keep brooming away their nests, smash the adults that you can find and keep debris piles to a minimum if not completely void on your premesis. This will discourage them from continuing to form webs and hideouts on your property in the future. The truth is - they are very hard to get rid of, once they are present in your home, shop or garden.
Crab Spiders camouflage in flowers and eat bees and butterflies that come in search of nectar. Crab spiders can kill insects much larger than them. Mother Crab spiders do not eat. Giant Crab spiders eat cockroaches and pests that crawl in roses. They eat insects that come close. They eat bees. Crab spiders use a rapid position to kill their food. They eat pests that are near. Crab spiders catch their prey with their front legs
Certain wasps predate spiders. Certain spiders predate other spiders Certain birds predate spiders. Small mammals will also predate spiders, as will some frogs, lizards, ants and humans
