The aerosol spray has a wide reach and coverage. However, the chemical substances in aerosols can be harmful to children and domestic animals.


Using spider killer spray as aerosols is one of the most common methods on how to kill spiders.

They are similar to aerosols but less powerful and have closer reach. But on the other hand, they are safer to use around people and animals.

They are also convenient to use and bring instant results.

However, some products can contain an irritating odor. Ensure that you use a mask while spraying.


Traps are the most old-fashion but effective method of pest control treatment.

These glue traps are easy to use and work wonderfully for small infested areas. You can use spider traps around humans since they are non-toxic.

Another effective method to eliminate spiders is spreading insecticide dusts in front of their nests.

You can use dust mites both indoors and outdoors.

Ultrasonic Pest Repellents

Traps and sprays pest control products can be harmful if you don’t use them correctly. Therefore, the easiest method to kill spiders is using ultrasonic spider repellent.

They emit sounds that attack the pests’ nervous system and finally chase them away from your house. These devices are 100% human-friendly, but they won’t give you the instant results as the chemical sprays.
