Features
  • Active Components: Gamma-Cyhalothrin
  • Residual Effect: 12 months
  • Cover Area: n/a
  • Weight: 12.2 oz.

The Spectracide is an affordable option that provides enough power and good coverage. The AccuShot wand on it is also extremely convenient, as it avoids hand strain with a continual action power sprayer, so no pumping or squeezing is required. The battery-powered wand may also be extended for greater precision. The active component of the Spectracide bug spray is Gamma-Cyhalothrin, which is a pyrethroid. Pyrethroids are generally considered to be less harmful than organophosphates (another class of insecticides), but they can still be toxic if inhaled or ingested, so it’s important to use them carefully. This product is designed for indoor and outdoor use, and the clear formula leaves no oily residue. It has fast-acting kill-on contact and is effective against a variety of insects, including ants, roaches, spiders, fleas, and ticks. The Spectracide bug spray is also unscented and water-based, so it shouldn’t leave any lingering odour.

The Spectracide Bug Stop Home Barrier and Miss Muffet’s Revenge Spider Killer from our list share several similarities. First, both chemicals can be used for indoor and outdoor applications. Additionally, both chemicals can last for up to 12 months. Finally, both chemicals don’t leave a lingering odour after application. However, the former kills insects when they come into contact with it, while the latter repels the insects, preventing them from coming into your home.

    What do we love it for?
  • Battery-powered wand
  • Low price
  • No-odour residue
  • Fast-acting formula
  • 12-month control
    What were we disappointed with?
  • May be harmful to humans and pets if they are in contact

Things to Consider

Having one of the best spider sprays is a perfect way to keep your home and garden free of these pesky pests. These sprays are usually safe for kids and pets, plus non-toxic for your favourite plants and flowers. It’s because the best spider sprays are made of natural ingredients or non-toxic chemicals, but you should check them before purchasing one.

Active Components

7 Best Outdoor Spider Sprays to Keep Your Home Safe
Pyrethrin is a natural insecticide that is derived from chrysanthemum flowers.

Active Ingredients

There are several popular active ingredients in spider-killing remedies: pyrethrin, bifenthrin, zeta-cypermethrin, gamma-cyhalothrin, and deltamethrin.

  • The most common is pyrethrin, which is derived from chrysanthemum flowers. Its advantage is that it is effective even at lower concentrations and can reduce the population of pests colonies that are harmful and sometimes dangerous for humans, pets, crops, and livestock. Repellents made of pyrethrin are effective against mosquitoes, fleas, and ticks that can carry different deadly diseases. Plus, it’s perfect for getting rid of ants, spiders, and lice. In spite of its high efficiency, it’s safe for use around pets and children.
  • Bifenthrin which is considered to be a pyrethroid insecticide has a pretty unique working principle – it affects insects’ nervous system, which leads them to death. Be aware that bifenthrin is prohibited from using around water with fish because it’s highly toxic for any aquatic organisms.
  • Zeta-cypermethrin stands for a synthetic pyrethroid insecticide that is effective against a wide range of different insects. Its working principle is to cause nervous system dysfunction, which kills the target pest. The main advantage of zeta-cypermethrin is that it’s suitable for protecting plants safe from pests. It’s approved to use on many different crops.
  • Another synthetic pyrethroid is gamma-cyhalothrin. The pros are that insecticides made of it usually have a long residual effect and are perfect for protecting large areas. But, there are some downsides that gamma-cyhalothrin is toxic to fish and any other aquatic organisms. Note that it’s important to use a face mask when applying it indoors because it can be harmful to humans if accidentally inhaled or ingested.
  • Finally, deltamethrin is another powerful insecticide against spiders. But as previous one, it’s dangerous for any fish and aquatic creatures. Also, due to its high-efficiency level, it’s toxic to humans and pets, especially when inhaled or touched. So be sure to use a face mask and protection gloves when applying it, and give it time to dry.

Besides chemicals that are effective against spiders and other pesky creatures, there are some natural spider repellents that are usually made of natural oils like cedar oil, peppermint oil, and vegetable and palm oils. Such repellents are safe to use around kids and pets, have fresh and pleasant odours, and are effective against a wide range of pests. But keep in mind that peppermint oils are toxic to plants, so it’s better not to use them around flowers and in the garden.

Residual Effect

Outdoor spider sprays’ residual effect means how long the remedy will protect your home and yard when being applied. The effect length depends on the type of the product and its active ingredients, but usually, outdoor spider killers are considered to be long-lasting, so you can forget about any pests for more than several weeks.

Coverage Area

Coverage area size shows what space can be protected by one spray. Usually, outdoor spider remedies can cover up to 5,000 sq.ft., which is enough for large yards and houses. But keep in mind that natural sprays can protect only small areas, so you’ll need several bottles to cover the whole garden or house.

How to Prevent Spiders Around Your Home: Tips

Besides using one of the best outdoor spider sprays, there are some other ways to keep spiders away from your house and garden. By following them, you’ll forget about any pesky pests, including spiders:

  • Clean your house weekly and throw rubbish away every day. Spiders are likely to hide in shady spots and places that provide them such space, so remove everything that could be a shelter for them.
  • Seal up all cracks or openings around your house. Inspect thoroughly all your windows, doors, and other possible entry points to make sure that there are no cracks and gaps that spiders could go through.
  • Remove all the plants that are attractive to spiders. Spiders tend to build their webs on plants because there are usually a lot of insects for them to eat. So if you have different plants inside or outside your house, it’s better to move them far away from your home to protect them.

Get spider traps, foggers, or repellents. If you’ve found out that there are spiders have invaded your home, using one of these remedies is a good rule of thumb. To make it easier, we’ve made a guide with the best foggers for spiders to protect your home for longer.
