Bleach and freezing are your best bets here. The soft exoskeleton of spiders and spider eggs is no match to household bleach. Create a mixture that’s half water and half bleach and spray it directly onto the egg sac, and the spider eggs will be killed in less than five minutes. Freezing the egg sac or drowning it in cold water is another option.

Using audio and visual methods to discourage birds might work initially, but birds tend to acclimate to them over time. While chemical deterrents can show some effectiveness, their results can be inconsistent. Some may dissipate too quickly, and there's a risk they might cause unintended damage to your surroundings. Additionally, birds might become immune or resistant to the impact of such treatments.

The fastest method to get rid of moles is, unfortunately, not the most humane one. Poison baits and traps are the quickest way to get rid of a mole infestation. 

However, the poison can be dangerous and even deadly to other visiting animals, such as birds, cats, and dogs. The toxins can even affect predatory birds who eat the moles after they've consumed the poison.

Getting roaches to completely go away will take a lot of effort, and they hardly ever go away on their own. You will likely need a combination of home treatments, like roach sprays and traps, and regular visits from an exterminator, to control an infestation. It can take awhile for these treatments to start working, and you’ll need to stay on top of replacing old traps and having additional extermination services, plus keeping your home clean and decluttered, to deter roaches.
