OK guys/ gals,
I've got a problem on my hands. There have been many spider web strands on the outside of my truck lately. Then today I look at the weather stripping on my doors, and 3 out of 4 of them had a spider web "cacoon" or whatever you call them on the weather stripping (I cleaned them off obviously). I'm sure it's because I park underneath trees often and a lot of them probably have a lot of spiders. I know you're gonna say "then don't park underneath the trees". But the problem is that I often can't park anywhere else. I go hiking with my dog ALOT and all the parking spots are underneath trees. So far, I have not seen an actual spider in or on my truck, but I'm nervous they're somewhere.
The BIGGEST problem though, is that I am absolutely petrified of spiders. If I'm driving and there's one next to me or something I know I will completely freak out and crash and die in a horrible accident

.
So this is where I need your help. I know they have those "bug bomb" things, but I would rather not use something like that since if it can kill spiders and other insects, what's to say it can't harm my dog or myself or someone else in my truck over the long term exposure? In your experiences, what is the best way to go about making sure my truck is spider free and spider proof without using one of those "bug bombs"?
And P.S. You don't have to say it, and I know you're thinking it, I know I'm a complete wuss when it comes to stuff like this.
Thanks for any help!
