In the world today we have roughly about 40,000 specie’s of spiders.They are categorized as either active hunters (burrowers and others) or passive hunters (web builders and ambushers). The general perception of spiders is that they are dangerous and threatening is likely due to their appearance, people’s belief’s and the widespread presence of arachnophobia (the irrational fear of spiders). Despite their reputation, most spiders are beneficial organisms. Although some species have toxic venom, the repercussion of spider encounter are minimal compared to other pests such as ticks, mosquitos, wasps and bees.
Spiders can however, be difficult to control. They make very light contact with treated surfaces, moving lightly and quickly across them with a small footprint that can avoid them from absorbing a lethal dose. Spiders’ sensory organs allow them to detect minute amounts of chemical repellents on treated surfaces, and they quickly learn to avoid these areas. Chemical treatments need to be applied directly on passive hunters and their egg sacks as they avoid chemically treated areas due to them remaining in their web.
Tips for Spider Control for Homeowners
- Vacuum cobwebs to remove spiders and their egg sacks.
- Remove outside general waste and rubbish, firewood, leaf and plant litter and other clutter from around your home.
- Trim back branches away from buildings, especially anything making contact with or hanging over your home.
- Mow the grass right up to and under the foundation ( if you have a high set home).
- Install weather stripping around doors and windows.
- Plug holes with copper wool, foam or wire screen.
- Seal around all pipes, cracks in the eaves and other cracks found around the structure.
- Manage outdoor lighting by using bulbs that attract fewer insects, install motion sensor lights to prevent lights being on when not in use and attracting pests.
- Keep window curtains closed at night to limit light emitting from inside the house and attracting pests.
