Spider webs under patio furniture

by Genie
What can I do to prevent spiders from webbing the undersides of my lounges, chairs and tables? I don't particularly want to spray poison because I don't want to come in contact with it.

    Any mint essential oil detracts them. They smell through their feet so the more you make them not like where they are the faster they will leave. Hope that helps.
    Spiders detect smell with scent sensitive hairs located on their legs. A sense of taste in their mouth is missing. A spider feels her prey with chemo sensitive hairs on her legs and senses if the prey is consumable.

    Spiders hate peppermint. Spray with a mixture of peppermint oil and water.

    I would clean more often, and put some Moth Balls under it. The Moth Balls do no harm to any our plants. Enjoy, J.

    Control of spiders is best achieved with an integrated pest management (IPM) approach that includes multiple tactics for prevention, exclusion, and population reduction. Since the type of spider will determine the necessary control actions, start by identifying the spider involved.

    Spiders are not generally harmful. Tolerance for spiders and simple capture and removal are recommended whenever possible. However, dangerous spiders such as the black widow and brown recluse, both very rare in the upper Midwest, require immediate attention and control.

    Eradication of all spiders from a home is difficult and unnecessary. Properties located in areas favorable to spiders, such as by rivers, lakes, or fields, are more likely to have large numbers of spiders. Spiders also will be more numerous in areas with a large supply of insects that serve as a food source for spiders.

    Each situation is unique, but the following guidelines describe the integrated techniques that can be used to control spiders.

    Use the following techniques if accidental invasion by wandering spiders from outdoors is a frequent problem or to reduce an unacceptable number of spiders around your home and prevent spiders from getting inside. Otherwise, spider control in the lawn, landscape, and garden is not recommended because spiders are beneficial and an important component of the ecosystem.
    • Remove piles of bricks, firewood, and other debris that may serve as suitable homes for spiders or move them further from your home.
    • Keep grassy or weedy areas near buildings cut short.
    • Trim back shrubs and other plants that directly contact your home.
    • Periodically remove webs with a broom, vacuum, or a hard spray of water.
    • Remove and destroy any egg sacs or spiders that are found.
    • Check to be sure screens fit tightly. Replace any screens that fit poorly or are damaged.
    • Reduce outside lighting to minimize attraction of insect prey that can encourage spiders. Yellow lights are less attractive to insects than mercury or sodium vapor lights. When possible, place security lights on a pole shining toward a door rather than on the building above the door. This will reduce attracting insects that spiders feed on to the building.
    • Caulk or seal cracks or gaps around the foundation, doors, and ground level windows.
    As a last resort, lightly apply a broad-spectrum insecticide labeled for the exterior of buildings on the outside of your home to reduce invasion by wandering spiders. Spray under siding, in cracks and crevices, and other places where spiders may hide. General treatments on the siding or other surfaces are not effective. Read and follow all pesticide label directions.

    Regular housecleaning is very important in the control of spiders indoors. Large, persistent spider populations indoors indicate the presence of a significant insect population that serves as their food.
    • Capture and discard or remove individual spiders that have wandered inside.
    • Remove papers, boxes, bags, and other clutter to minimize favorable sites for spiders.
    • Remove webbing with a broom or vacuum, and destroy any egg sacs and spiders that are found. Look especially around windows, in corners, and in relatively quiet places.
    • Sticky traps such as small glue boards or cockroach traps can be used to monitor for presence and abundance of spiders. In limited circumstances sticky traps also may provide some level of control. Place traps along walls, under furniture and appliances, and in other undisturbed locations.
    • Eliminate insects that serve as a food supply, especially when large numbers exist. Check particularly in and under webs to see what insects have been captured.
    • Osage orange fruits, also called hedgeballs or hedge apples, are sold in stores and alleged to repel spiders. They are not effective and their use is not recommended.
    You can supplement your sanitation efforts with an insecticide treatment. Lightly apply insecticide to cracks, gaps, and other places where spiders may hide. General treatments on surfaces and fogs are not effective. Most insecticides labeled for ants and cockroaches are also labeled for spiders. These products are commonly found in ready-to-use aerosol and liquid formulations. CAUTION: Read all label directions carefully before buying insecticides and again before using them.

    Wipe underneath with a cloth or sponge with AVON Skin So Soft on it. Keeps furniture nice and insects HATE the smell. There are now three scents to choose from, but I prefer the original. It has been am insect deterrent for over 60 years!
