HOW to GET RID of BLACK WIDOW SPIDER – POISONOUS SPIDER

Black widow spiders are known that the female black widow eats the male after they are done mating, which is only a belief. A female black widow spider is black with a red hourglass looking mark on her abdomen. The adult male black widow spiders are harmless. They are considerably smaller than the female size, about half the size and usually has yellow or red band with spots on their back. The legs are longer in proportion to his body than of female. The younger black widow spiders are primarily orange to white but will acquire more black as they get older.

INSPECTION

Black widow spiders can be found around firewood piles, in trash, rubble piles, under or around houses and privies, sheds and garages. They can also be found under eaves, in storage bins, toilets and sheds, meter boxes, and other undisturbed places. The female black widow spider hardly leaves the web and can rebuild or change the web based on her needs. The black widow spider spends most of the time during the day on her web and most of the time, she will be hanging upside down.

SAFETY EMERGENCY PROCEDURE

A person might not always feel the black widow spider bite until later.

  1. The very first sign of a bite is a small swelling and might have two small red spots in the center of the swelling. After about 3 hours or later, the place where a person was bitten will become more painful.
  2. Common reactions are said when a black widow spider bites is an entire body ache especially in the legs.
  3. Other symptoms: alternating salivation, dry-mouth, and paralysis of the diaphragm, excess sweating can occur.
  4. The poison injected can cause abdominal pain similar to appendicitis as well as pain to the muscles and/or to the soles of the feet. Most of the symptoms disappear within 2-3 days.
  5. A person bitten should seek immediate medical help and get treated.

The black widow spider only bites when she is protecting her eggs and feels as if she is in danger as a defense mechanism, so if you find a spider, please do not touch it with bare hands or feet.

CONTROL METHODS

Prevention:

To help prevent a black widow spider from making a web in your home, you will need to remove all the places where they might hide. Everyone should always remember to wear gloves and not to walk outside barefoot whenever you are removing or cleaning out the places that they might live or hide. Also, remember to dust and vacuum around windows, corners of rooms, and under furniture. Also to trim weeds around the building and remove debris so the insects and black widow spiders will not be attracted to living on or in the house. Remember to makes sure that you seal openings and install screens and door sweeps to prevent black widow spider from moving indoors. If a black widow, webs, and eggs sacs are found, vacuum all of them and remember to DISPOSE the bag after each vacuum. Also, with regular pest control, it will reduce the number of insects in your home and in turn it will also reduce the chance of a black widow coming into your home.

Crack and Crevice Treatments:
This treatment is generally applied with a liquid spray (LambdaStar 9.7% CSFenvaStar EcoCap ),  dust (DELTA DUST), and aerosols ( CY-KICK AEROSOL) to be applied to small cracks and crevices in a structure with spiders may live and hide.

For liquid spray application, you will need to have a pressure sprayer or a gallon sprayer (CHAPIN 1 GALLON SPRAYER). For (LambdaStar 9.7% CSFenvaStar EcoCap ) you will need a low pressure system with a pinpoint or variable pattern nozzle to apply the spray mixture to areas such as floors, cracks and crevices, in and around baseboards, walls, expansion joints, around your windows, and under your furniture. You will need to apply using the amount that is said on the label and may need to reapply if needed.

The dust application is simple. However, when using dust please be cautious especially when children and pets are present. Use dust only in areas where it is hard for them to reach. The DELTA DUST, you will need to use a BELLOW BULB DUSTER . When using a  DUSTER  for DELTA DUST, you will need to fill the duster with the dust as directed in the label and apply DELTA DUST to cracks, spaces or bearing joints between the wooden members of the structure. Apply lightly and uniformly to the infested area. DO NOT OVER USE DUST. The aerosols are used by spraying into the crack and crevice. Since aerosols and liquid sprays are liquid be cautious if you are spraying near any electric equipment or outlet.

Directly getting rid of the web that the spider has made already you will need to use COBWEB ELIMINATOR. You will directly spray the COBWEB ELIMINATOR on the web and it makes it easier to remove the web without leaving any of it behind. It also discourages the reformation of webs. The COBWEB ELIMINATOR has a mildly acidic odor to it, but it is indicating that the product is effectively working.

Barrier Treatments:
This treatment is applying a liquid spray to zone around on a structure that any pest might enter the zone. These are sometimes called a perimeter treatment where soil areas are adjacent to a structure as well as a portion of the lower foundation wall next to the soil are treated (LambdaStar 9.7% CSFenvaStar EcoCap ).

Barrier treatments or Perimeter treatments are used just around the structure of your home to create a barrier for you home. We suggest that you use a gallon sprayer as well (CHAPIN 1 GALLON SPRAYER). Using the directions of the amount and the rate that you should use, apply a continual band of insecticide around a building foundation and around windows, doors, service lines entrances, eaves, vents, and other areas can greatly reduce the potential for entry by pests. Also apply a band to the soil 6-10 ft. wide around and adjacent to the building and treat the building foundation to a height of 2-3 ft. where peats are active and may find entrance. Apply as a coarse spray treatment to thoroughly and uniformly wet the band. For better results, this treatment needs to be done regularly to reduce the amount of insects and to keep your house insect free.

    Hi,we have recently been checking on a house we will soon buy and today we went to go check it out again and right where the step of the pool there was a huge black widow,my dad killed it..i was scared i knew it was a vlack widow since we went to the zoo that same day ..i really am terrified that it would bite me or my family :-/this ouse has been vacant for 5 years and there is 3 big sheds which most likely have even more spiders even snakes i just want them out!! Any tips ? please help

    Yikes! That doesn’t sound too welcoming. But there is a simple fix. I would recommend that you use Temprid SC and thoroughly spray around the outside perimeter of your home and indoors along the baseboard area and along all window and door frames. You should also repeat this treatment in your sheds. Once you get the insect population controlled it will naturally decrease both the spider population and snake population.

    Recently have found some black widows in my house. I did vacuum some egg sacs out of the vents in the floor. I was wondering if it is safe to spray the Phantom insecticide in the vents and the furnace room. I have a baby due in a few months and want something safe for him when I turn the furnace on. Thanks

    I would not recommend spraying inside the vents, especially with the new baby coming… Instead it would be perfectly fine to spray around the premises of the vent area.

    Everything I have read has stated Black Widows aren’t in Wisconsin. Well, I live in central Wisconsin and have been battling an infestation of black widows IN MY HOUSE! We live in the woods, and as a result have always had to try and get rid of wood roaches (and german roaches, yuck! And I keep a clean house!) in our basement. Last year I didn’t see a single roach in the house and thought YAY they’re finally gone! Shortly after I started finding black widows hanging around light fixtures and in the doorjams. Coincidence? Or do black widows eat roaches? Ugghh. I’m frustrated with pests! Just last night I went into the office we built in the basement, looked up, and there was a large black widow with her long legs… I killed her of course!

    And I should add that I’ve found them in our tractor shed, on the outside of my house, and even under my bird baths outside. But only started seeing them last year.

    We have a product called Zenprox EC which is labeled for black widow treatment. Its also labeled for general pest control so it will help you eliminate their food source which will also natural decrease the black widow population in the area. Good luck!!

    I live just north of Mexico in California and in the past few days I’ve caught 2 of what I think are male black widows. They have a black cephalothorax, a mottled brown abdomen, and banded orange-brown legs. What is odd is that the males seem larger than I would expect, closer to the size of the female, but they have pedipalps. Am I just wrongly identifying the spider? And, if they are black widows, is it likely that there are more, perhaps some hiding females? The guys that I caught were just wandering around in the middle of the day…

    It would be hard for us to tell by just the description because there are a more than a few spiders that may qualify under the description as mentioned above. However if you could send us a picture to INFO@PESTMALL.COM we could possibly take a closer look and try to identify it for you. Regardless, if you need a product for spiders including black widow spiders I would recommend Talstar Pro. Should you have any further questions, please feel free to contact us!

    I found black widow spider from my home close to the drinking water tank. Where the place found its fully roofed place and I found lots of spider nets with colorful other many types of spiders also.
    When I found it immediately informed to the Maldevian police service and they take action.
