Does vinegar kill spider eggs?
Vinegar kills spider eggs by dissolving the silk that protects the eggs. After the egg sac is destroyed, it will burn the unhatched spiderlings. Combine 4 ounces of white vinegar with 2 ounces of warm water and spray it on the spider eggs.
Spraying white vinegar on a spider’s egg sac will destroy it on contact and all the eggs will be eliminated. The egg sac is made of silk that vinegar can dissolve. However, some spiders make thick egg sacs from silk and this may take time for vinegar to destroy.
If the woven silk that contains the eggs is not extra thick, then vinegar will destroy it when sprayed close enough. Ensure that the white vinegar solution is sprayed close enough to maximize the efficiency rate.
Not all types of vinegar can destroy a spider’s egg sac. It is only concentrated white vinegar and 100% pure vinegar that can do the job. The silk is naturally slippery and using weak vinegar with low acidic concentrations will have no effect on the spider eggs.
