Spiders are generally considered to be among the toughest home invaders to eradicate. Due to their unique biology, they are not very receptive of chemicals, and their long legs make it difficult for sprayed down pesticides to come into contact with their bodies. For these reasons, and for the simple fact that many people have a phobia of spiders, people like to be educated on how to remove spider problems should they encounter one. The first measure you should take is to try to block any possible entry points. Common entry points are cracks and crevices in the floor, in tiles on the ceiling, and in the corners or along the creases of walls. Filling these openings with something such as wall filler putty is a good prevention technique to take to stop any spider invasion before it occurs. However, if spiders have already infiltrated the home, then before covering these tight openings, it is best to treat them with an insecticide. Because the openings are so tight, the spiders will most likely have to brush their bodies along the wall as they squeeze through which provides a prime opportunity for body contact with the insecticide.
In addition to using insecticides on cracks and crevices, another common treatment option is to use glue boards or sticky traps. Glue boards tend to cover more surface area but some sticky traps can be folded into a square to prevent the capturing of intended items and objects. Neither uses a pesticide, and in fact, most of them do not use an attractant, usually not even a scent. This is because the best mechanism for luring a spider in is to present a visual cue of its prey, such as an insect. If a bug is caught on the board or in the trap, a spider is much more likely to follow suit and approach the trap. The best place to put these traps is in dark, quiet, or moist places such as in a closet, between furniture and a wall, or in the corners of a basement. Lastly, the best measure to take is to maintain a clean and healthy living environment and to eliminate other bugs. Spiders are basically predators hunting their prey, and so eliminating their food source of bugs will prevent more spiders from appearing. Also, there is no harm in having a swatting stick or a rolled up newspaper to strike and kill any spider or bug on sight. For difficult spider infestation problems, EHS Pest Control can perform an extensive inspection of your house to localize potential problem areas and to provide more specific variations of these treatment options.
