I purchased my car about 2 months ago and roughly 3 days after I washed it I saw it in direct sunlight for a second and saw this. I about had a panic attack lol. I've been seeing a few actual spider webs on the car the past few months (..black car doesn't help!), but I guess I need to go back and spray some of the crevices I might have missed with my bugspray. All the garage and garage door seals are about to be redone at my house too...damn hail storms and high winds. Gotta love Oklahoma.
By the way, if you're having a problem with spiders or anything....don't buy the overpriced stuff from the stores. Pick up the Chapin 1 gallon sprayer on Amazon for like $10 and the 3/4gal. Talstar Pro from Amazon and you're good to go for years. This is what 99% of professionals will use when they come out to 'professionally' spray your house. Dries clear, you can spray it anywhere, concentrated (1oz Talstar Pro to 1gal water), etc. Great stuff. So glad I heard about this instead of buying Ortho or whatever...over and over and over.
