Pest Control FAQs, answered by experts

You can take multiple approaches to keep animals out of your edible landscape. You can use natural repellents such as mint and cayenne pepper to deter them from your garden. You can also build a fence (or opt for a privet hedge) or keep the most enticing plants in a sectioned-off area. The most efficient method of keeping your four-legged guests at bay is to determine what animal it is and create a customized plan for them. 

Honey bees are most likely to swarm during spring and early summer, typically from April through June, as colonies expand and prepare for new growth. Swarming occurs when a hive becomes overcrowded, prompting the queen and a group of worker bees to leave in search of a new nesting site. During this time, you may notice a temporary increase in bee activity around your property.

Consumer-brand foggers or bug bombs are considered safe overall. Still, it's essential to read the instructions carefully as the vacating time varies depending on the type of bug bomb you use. Most of the time, it's advised that all humans and pets are out of the area for at least two to four hours after initiating the fogger process. It's also a good idea to vent the space by cracking open some windows for several hours after you're back inside.

Drain flies aren’t likely to make you sick and typically aren’t harmful to humans. They don’t bite or sting; however, they can cause allergies. In some individuals, they can also trigger asthma. The main issue with these little bugs is that they’re annoying, unsightly, and unsanitary. Like all flies, they can spread bacteria from garbage or your sewer system.

If your house is full of things that attract spiders, you’re more likely to have a population explosion. When you have lots of cracks leading to warm, secure spots in your home, why wouldn’t they want to come in? Especially if your home has plenty of other meal-ticket insects, like flies, roaches, and fleas. Sealing up obvious cracks and gaps and keeping your house bug-free makes it a less appealing place for spiders.
