These spider sprays will take care of the problem and then some. The issue rests with non-targeted species.
Where Do Spiders Live?
Spiders can live anywhere from your attic to deserts and even underwater. They prefer places where nothing will disturb, often lurking in the dark corners of a room or garage. Part of the reason is that they are predators and depend on stealth to capture their prey. They have existed for a long time with fossil evidence going back 318 million years ago.
Spiders also have an affinity for water which is why you’ll see them in damp basements. The other factor affecting where they live is the availability of food. They eat insects and sometimes spiders too, depending on the species of which there are more than 40,000 types. They typically live up to two years, though some such as tarantulas have a 25-year lifespan.
Should I Worry If I Have Them In My Home?
Having spiders in your home raises two red flags. First, there is the invertebrate itself. Two species, the black widow and brown recluse, have a venomous bite that can harm humans. The wolf spider also poses a risk, but it’s not nearly as dangerous as the other two. If you have small children or pets in your home, your concern is well-placed.
The second issue involves their prey. These arthropods live in areas where they can find food. That means you likely have other pests in your home as well. Fortunately, many spider control products work on them too, making them an excellent value for the money. However, that brings up another issue which we’ll discuss next.
Are Spider Sprays Safe to Use?
The essential thing to remember is that the purpose of these products is to kill pests. Many will do it on contact. You’ll see pesticides with a residual effect too which provides significant clues about the safety of these sprays. A lot of them have active ingredients from the pyrethroid class of chemicals. These are synthetic versions of the natural product called pyrethrins.
You’ll find pyrethroids in other types of products such as dog flea sprays. Note the use of the word, dog. These ingredients are highly toxic to cats. If you have one as a pet, use them with caution in your home to prevent accidental exposure.
There is no question of their effectiveness. These spider sprays will take care of the problem and then some. The issue rests with non-targeted species. Many are broad spectrum which means they’ll kill a wide variety of insects including the beneficial ones like honeybees. They may also affect fish and other aquatic wildlife too.
We strongly urge you to read the label’s instructions and cautions in its entirety before using it inside or outdoors to minimize the risk of hurting other species. Don’t forget to look over the first aid advice too to protect yourself, family, and pets as well.
How Can I Prevent a Recurrence of Spiders?
The best way to control spiders is to avoid making your home inviting to them. That means cleaning up areas where you prepare food to prevent an insect infestation that will, in turn, lure the predators to your dwelling. Also, empty any sources of standing water in the yard or basement.
The next thing you need to do is to focus on the access points to your house. Patch up any holes in your foundation including the spots where utility lines enter your home. The same precaution applies to the exterior doors and screens. Remember that it doesn’t take a large opening for insects to get inside.
You likely find that dealing with spiders is a seasonal issue. Like other pests, they retreat to warmer areas when fall approaches. Controlling them isn’t a once-and-done solution, but instead, it’s an ongoing battle. Using different types of products such as repellents can help by creating additional barriers to keep them from entering your dwelling.
Finally, use pesticides that have a residual effect for a longer lasting solution. The length of time depends on the ingredients and their concentration. Bear in mind that the manufacturers have to test all products that are EPA-registered. Use them as directed in the recommended frequency for the best results. Only apply them as stated for the safest use.
