Spider Repellant


A reader asks: I am looking for a grapefruit sized, avacado colored fruit or vegetable that is used to repel spiders. I have seen these used, but don't know where to get them?

Dear Reader: Every profession has its home remedies and people swear by them. I believe if you feel strongly enough about something and it does not hurt the environment, give it a try.

It is said that the fruit of the Osage orange tree, which is also known as a hedge apple or spider ball, can repel spiders. This theory is widespread in Midwestern states where the trees are common. Apparently, putting these aromatic hedge apples around the exterior walls of a house in the fall will keep spiders from coming inside.

Problem is there is no documented evidence that spiders are repelled by

Osage-oranges. Spiders can be found living on Osage orange trees. You can even find spider webs right on the fallen fruit. In fact, spiders seldom show any sign of being able to detect airborne odors.

Of course, once these stories get rolling they develop neat little twists. In some versions of the story the hedge apple can repel everything from cockroaches to mosquitoes to chicken mites. Research has shown that there are chemical compounds in the fruit that repel cockroaches, although the fruit itself does not.  One method that definitely works is to pick up the hedge apple and smash the offending bug with it. 

Osage oranges are even said to deter mice, but we know that squirrels regularly chew through these fruits to get the tasty seeds inside. So, using the hedge apple as a rodent repellent seems pretty ineffective.

In the Pacific Northwest where Osage oranges are fairly rare, Osage oranges have been replaced with horse chestnuts. Maybe its coconuts in Florida.

Actually, there is some research that would suggest hedge apples do well in repelling various insects. There is a chemical in the oil extracted from the fruit called elemol, which has properties similar to DEET in repelling insects. Since DEET doesn't repel spiders, I don't see why a hedge apple would work either. But, I hate wolf spiders (huge but harmless), and our house used to be full of them. As long as I keep hedge apples around the house I don't see any. As soon as I throw the hedge apples away, they come back. Maybe they're following the bugs that are repelled by the apples...I don't care, as long as the spiders are gone.
