Types of Spiders
Spiders belong to the Araneae order, which contains more than 45,000 species. Spiders are divided into two groups, the Mygalomorphae and the Araneomorphae. The Mygalomorphae are the primitive spiders, which are usually large and have heavy bodies with long legs. The Araneomorphae are the modern spiders, which are usually smaller and have lighter bodies with shorter legs. Examples of Mygalomorphae spiders include the tarantula, trapdoor spider, and the funnel-web spider. Examples of Araneomorphae spiders include the wolf spider, jumping spider, and the orb-weaver.
Most spiders produce eggs that are laid in a silken egg sac. The egg sac is usually hidden in a safe area, such as a crack or crevice. The female spider guards the egg sac until the eggs hatch. Killing the egg sac is an effective way to eliminate the spider infestation.
Brown Widows
- Brown widows are known for their brown and tan coloring.
- They are part of the Latrodectus genus, which is known to be extremely venomous.
- The female brown widow is identified by an orange hourglass shape on the underside of its abdomen.
- Brown widows are known to lay eggs in clusters, usually containing 100 to 400 eggs.
- The eggs are usually laid in a silken sac, which is usually attached to a stable object, such as a fence or outdoor furniture.
- The eggs are usually killed by extreme temperatures, insecticides, or direct physical contact.
Black Widows
- Spraying insecticides like pyrethrin or carbaryl around the area where the spider eggs are located can help in killing them.
- The use of a vacuum cleaner to suck out the spider eggs is also effective.
- Applying insecticidal dust in cracks, crevices and other places where the spider eggs can be located can help in getting rid of them.
- Using a mixture of soap and water to spray on the spider eggs can help in killing them.
- Setting sticky traps around the area can also help in trapping the spider eggs.
Other Types
- Vacuuming: Vacuuming often helps to remove spider eggs from carpets and furniture.
- Silica Gel: This substance works to absorb the moisture from the eggs, killing them in the process.
- Diatomaceous Earth: This powder absorbs the oils and waxes from the egg, rendering it unable to hatch.
- Steam Cleaning: Steam cleaning helps to penetrate the egg and kill it.
- Borax: This powder is effective in killing spider eggs.
Biology of Spider Eggs
| Size | 0.5 – 1 mm |
| Shape | Round, oval or cylindrical |
| Color | White, yellow, orange or red |
| Texture | Smooth or spiny |
| Material | Silk |
| Number of Eggs | Up to hundreds |
Spider eggs are much smaller than those of other arthropods, measuring only 0.5 – 1 mm in diameter. They can be round, oval or cylindrical in shape, and their color can vary from white to yellow, orange or red. The texture of the eggs can be smooth or spiny. Spider eggs are enclosed in silk and can range from a single egg to hundreds.
Reproduction Cycle
Spider eggs are laid in silken egg sacs that are typically attached to webs, bark, or leaves. The number of eggs in a single sac can range from a few to several hundred, depending on the species. After the eggs hatch, the tiny spiderlings remain in the egg sac for several days before dispersing.
The spiderlings may remain together for several more days, until they find a suitable place to live. They then start to spin webs and feed on small insects. After a few molts, they become adults, and the cycle begins again.
| Stage | Description |
|---|---|
| Egg Laying | Spider eggs are laid in silken egg sacs, with number of eggs varying by species. |
| Spiderlings | After hatching, the spiderlings remain in the egg sac for several days before dispersing. |
| Adulthood | After a few molts, they become adults, and the cycle begins again. |
Egg Laying Habits
- Most spiders lay their eggs in a sac or sacs of silk.
- The sacs are usually hidden in places such as crevices, bark or leaf litter.
- Spiders may lay hundreds of eggs at one time.
- The eggs are often guarded by the female until they hatch.
- The eggs usually hatch within a few days to a few weeks.
- The newly hatched spiderlings usually disperse within a few days to a few weeks.
Chemical Options for Killing Spider Eggs
- Diatomaceous Earth: This powder is made from fossilized algae and can easily kill spider eggs by dehydrating them.
- Insecticide: Insecticides can be used to kill spider eggs, though it must be properly applied to be effective.
- Pyrethrin: This is a natural insecticide made from chrysanthemums and can be used to kill spider eggs.
- Essential Oils: Some essential oils, such as tea tree oil, can be used to kill spider eggs.
- Boric Acid: This chemical can be used to kill spider eggs, but it must be used carefully as it can be toxic to humans.
Insecticides
Insecticides are a form of pesticide which are used to kill or repel insects. When applied, they can be effective in killing spider eggs and larvae, as well as adult spiders. Insecticides come in a variety of formulations such as dusts, aerosols, liquids, and baits. It is important to read the label to determine the most appropriate formulation for the type of spider infestation and the surface where it is to be applied. Dusts and aerosols are often used for treating cracks and crevices, while liquids and baits are used for treating larger areas. Insecticides can be hazardous to humans or pets if not used correctly, so it is important to follow label instructions carefully.
Natural Repellents
Natural repellents are a great way to get rid of spider eggs without using harsh chemicals. Some of the most effective natural repellents are garlic, peppermint, and citrus oil. Garlic can be crushed and spread around the house to repel spiders. Peppermint can be brewed into a strong tea and sprayed around the house to keep spiders away. Citrus oil can be mixed with water and sprayed in areas where spiders are commonly found. Another natural repellent is diatomaceous earth, which can be spread around the house to act as an abrasive material that kills spider eggs and other insects.
Non-Chemical Options for Killing Spider Eggs
Physical removal is an effective way to get rid of spider eggs. Using a vacuum cleaner is a quick and easy way to suck up spider egg sacks. Be sure to dispose of the bag or container away from the house so the eggs don’t hatch. Using a broom or dustpan to sweep up the eggs is another non-chemical option.
Insecticides that contain pyrethrins or pyrethroids can also be used to kill spider eggs. Although these are chemical treatments, they are usually derived from natural sources and are less toxic than synthetic chemical pesticides.
An even less toxic option is to use a damp cloth to wipe away the spider eggs. This method is particularly effective for egg sacs that have been attached to walls, ceilings, or other surfaces.
A final option is to use a natural insect repellent. Many natural products, such as essential oils, garlic, and diatomaceous earth, are known to be effective at keeping spiders away. This will not kill the eggs, but it will help prevent spiders from laying eggs in the first place.
Physical Removal
The most effective physical method of removing spider eggs is with a vacuum cleaner. It is important to vacuum around the areas where spiders may be nesting, such as window frames and door frames, as well as any cracks or crevices in the walls. Vacuuming regularly can help to reduce the number of eggs that are laid. Additionally, it is important to dispose of the vacuum bag after each use, since spider eggs can survive in the bag for some time.
In addition to vacuuming, physical removal can also be done by scraping off the spider eggs with a putty knife or other flat object. This is most effective when done on flat surfaces, such as walls and ceilings. When scraping off the eggs, it is important to be careful not to spread them around.
Finally, physical removal can be done by picking up the egg sacs with a pair of tweezers or a pair of gloves. This is most effective when done outdoors, such as in the garden or on the patio, as spider eggs can easily be spread indoors. It is important to dispose of the egg sacs as soon as possible to prevent them from hatching.
Vacuuming
Vacuuming is an effective way to get rid of spider eggs. Spiders often lay their eggs in small crevices around the house where they can be hard to reach. Vacuuming these areas will create suction, pulling away the spider eggs and sucking them up into the vacuum cleaner. It is important to empty the vacuum cleaner afterwards and dispose of the contents in an outside bin.
Trapping
Trapping is an effective method for killing spider eggs. It involves setting up traps to capture spiders and their eggs. Trapping can be done with baits, lures, and physical traps such as sticky traps, glue boards, and funnel traps. Baits and lures are used to attract spiders, while physical traps are used to capture them. When using baits, it is important to use the right bait that is attractive to the species of spider being targeted. Physical traps should be placed in areas where spiders are likely to travel, such as along walls, under furniture, and in corners. Inspecting the traps regularly and disposing of the trapped spiders and eggs is important in order to effectively kill spider eggs.
