How to get rid of Black Widow Spiders Naturally

You can kill the black widow without the hassle of going to the store to buy chemicals but by using the available resources at the disposal of your home. This method is not only convenient but also cost-effective.

The following are some of the natural ways you can use to get rid of the black widow spider:

Sanitization of the garage

Your first step to removing the black widow from your garage is to get rid of their webs which they depend on for shelter and food. Remove any spider webs by vacuuming high and low, paying particular attention to hiding locations such as corners and dark areas beneath the furniture. Egg sacs should be carefully targeted, and then everything should be safely disposed of in the vacuum cleaner’s canister shot.

If there are holes that black widow spiders are using to emerge into your garage, you should consider dusting the vents and later sealing such ducts to prevent further infestation. Before you close any gaps, make sure to spray the area with vinegar to kill the spiders. You can seal windows and doors with door sweeps or weather stripping. Make sure that your garage window frames and vent screens are tight-fitting and have no holes.

Remove Litters

You will need to reduce the amount of litter in your garage to make the garage an unsuitable environment and a less attractive place for black widow spiders. When cleaning and removing clutter, it is vital to wear protective gear such as gloves, long sleeves, boots, and hats to prevent spider bites since the spider may interpret the cleaning process as a threat and bite you in self-defense. You should insert the end of sleeves to your gloves and the end of your pants to your boots as an extra precaution when decluttering your garage.

Use glue boards or sticky traps placed against ages near entry points into your garage to catch and detect black widow spiders and consequently prevents further invasion of these spiders in your garage,

Use Strong Scents

Black widows are not fond of strong scents such as the smell of peppermint, eucalyptus, tea tree oil, and peppermint essential oils. You should therefore mix these items to create a potent concoction to keep the black widow away. Add the concoction you just made (or you could use a specific essential oil) to water to form a solution. Put the created solution in a spray bottle and spray to the dark corners in your garage, on the window ledges, and even beneath items stored in the garage.

Use vinegar

Vinegar is acidic. Its acidity kills the black widow spiders by burning their body in contact. The repellent is made by combining equal amounts of water and vinegar to make a mixture, putting the resultant mixture in a spray bottle, and then sprinkle it directly to the black widow spider or a spider’s egg sac.

Use Insecticides

Black widow insecticides can be applied as a dust or as a liquid. The insecticides that come in the form of dust are suitable for areas where humans are unlikely to enter, such as basements, crawl spaces, and window sills. Other regions, such as well-known webs, are well-suited to liquids. Insecticides will kill any existing spiders while also preventing new ones from appearing.

Black widow spider’s egg sacs are best targeted using oil-based pesticides like pyrethrin. When you find an egg sac, generously apply the pyrethrin, coating both surfaces as much as possible. The insecticide will kill black widows, and others will be discouraged from entering your garage.

Setting traps for insects

Because spiders eat other insects, removing flies, moths, grasshoppers, and earwigs reduces the food supply for spiders. Putting traps for these pests will automatically minimize a black widow spider’s chances of building her web nearby. Removing the spider’s source of food will successfully eliminate the black widow from your garage.
