Do this first

To start with, do a full examination of your home. Pests have limited needs, and generally only visit your home to satisfy the basics. Your home is likely either providing them a food source or a nesting source. You’ll need to figure out and eliminate that source, or find a way to block their access to it. Make sure to do the following in every area:

  • Remove clutter
  • Clean each area thoroughly — especially where food has been cooked or served
  • Figure out where any leaks are coming from, i.e. consistently damp or wet areas, and fix them so they are dry
  • Make sure food is covered right away after meals and leftovers are stored in air-tight containers (preferably in the fridge)
  • Look for any holes or cracks in window screens, walls, doors, etc., and seal them thoroughly with caulk or other means (this can easily be done by turning all the indoor lights on, outdoor lights off, and going outside at night to check for light coming out from anywhere it shouldn’t. Look closely and you’ll see any little holes and cracks that need to be sealed)
  • Do not store wood near or against your home — this makes a great hangout for everything from rodents to snakes to carpenter ants. Keep it at least 20 feet away
  • Keep bird feeders at least 25 feet from your house; rodents are attracted to the seeds that fall from them
  • Do you have shrubs or trees with branches growing against your house or windows? Trim these back so they aren’t touching your house
  • Keep your outdoor lights on at night to keep creeps of all kinds from crawling in (this may not always be advisable, and surely is not good for eliminating light pollution, so use only as needed)
  • Any outdoor food storage containers must be kept tightly closed, in a container that cannot be chewed or clawed through. Same with garbage containers
  • If you have a chimney, cap it

Once you’ve taken these steps, keep an eye out and see if anything additional is necessary to prevent pests from continued efforts to enter your home. Here’s what the pros have suggested:


  • Eliminate standing water in the yard, gutters, outdoor furnishings or toys, etc. in order to prevent mosquito breeding in the warm months.
  • The citronella geranium, more commonly known as the mosquito plant, contains citronella oil which is released when the plant’s leaves are pulled, ripped or chewed. This is said to repel mosquitoes from the area. Give it a try!
  • Note: Even as much as a bottle cap full of water can result in hundreds of mosquitoes. Be sure you dump anything that rain gathers in or snows melts in as soon as you notice it.


Keep flies from congregating and breeding on your property by cleaning up all animal feces immediately and keeping trash cans tightly closed.

Fleas, ticks, mites, etc.

Mix up a blend of pure organic cedar oil and water and spray it every night around your lawn and shrubs. It smells fresh and repels a variety of insects, many of which bite and cause a plethora of problems. It is said to kill their eggs as well.


Cut back any long grasses, weeds, or large open areas in your yard, and watch out for trees as well. Ticks like to hang around waiting for a pet, passing wild animal, or human to waltz by and then jump on them for dinner. Eliminate their hiding/jumping off points, and you’re halfway there.


While wasps and hornets are generally beneficial and harmless, they can be problematic when building their nests in areas where people congregate, children play, etc. It’s best to prevent them by doing the following:

  • rinse out all pop cans and bottles thoroughly before putting in recycling bins
  • clean up any spilled sweet drinks or foods immediately
  • bag up and dispose of garbage immediately
  • if you have fruit trees or bushes, clean up all the fallen fruits ASAP
  • keep your home clutter-free, including the attic and garage
  • avoid hanging anything colorful or bright out where they may be attracted; they are often drawn to bright things mistaking them for flowers

Garden pests

A variety of garden pests like aphids, spiders, beetles, mosquitoes, ticks, mites, and more are often controlled by this remedy. Blend up a quarter teaspoon of mild (preferably color-free, fragrance-free) liquid dish soap and two tablespoons of ground cayenne pepper into a quart of water (not too hot or cold). Shake thoroughly, let sit for several hours, then spray with plenty of pressure all over the plants. Spray from above, spray from below, spray from all directions. Do this in the evening or very early in the morning, and not if it’s a super hot day. Must be done weekly at least until you notice the pests have moved on.


While you’ll definitely need to remove their food or nesting source too (pay particular attention to areas of consistent moisture), this remedy may also assist you in showing cockroaches their way out of your home. Make a dough out of equal parts flour, sugar, and boric acid. Sit them around your home where you suspect or have seen roaches. The smell of the sugar should attract them. Once they start snacking, the boric acid will kill them.

While this is only 7 pests out of many, the task list we mentioned first should be sufficient to rid your home of all types of pests if done correctly and often enough. If you find you’ve tried everything and nothing works, contact an exterminator for help.

A pest problem in your home, whether it's rodents, birds, or insects, can really test your patience. Many invading pests are not only annoying to deal with, but some can damage your property and others pose serious health risks to you and your family. While there are all sorts of DIY solutions to pest problems, there comes a time when you need the services of a pest control professional.

When is it time to hire a professional?
Using DIY pest control products is certainly more affordable than hiring an expert, but these remedies are only effective for superficial problems. Consider the severity of your pest problem and the type of pests you're dealing with before going forward with pest control solutions you picked up from the department store.
Consider how big your pest problem is
If you have a significant infestation on your hands, sprays and traps from the home improvement store may be ineffective. To determine how big of a problem you're dealing with, look for the tell-tale signs of infestation.

When is the best time of year to spray for bugs? What you should know

Dealing with creepy crawlies is frustrating and exhausting, especially if you have to exterminate these invading insects year after year. Whether you're dealing with ants, flies, spiders, or roaches, having bugs in your house is more than just unpleasant. Many pests carry diseases and some can even cause damage to your home's structure with their burrowing, digging, and breeding habits. By engaging in a few proactive and preventative measures at the right time of year, you can minimize the bug population before it takes over your home.

The life cycle of most invasive bug colonies
In order to put preventive measures in place, it's important to know how and when these critters grow and multiply so you can plan your extermination around the times they're most vulnerable.
As winter approaches and the outdoor temperatures begin cooling down, pests start to creep indoors in search of a safe, warm shelter.  You may notice a few stray bugs during this time, but likely not enough to cause any alarm. Unless you hire a professional for an inspection, you probably won't even notice them.
When the weather outside is frightful, you won't see much activity from pests in your home. They are dormant and hibernating in a safe and inaccessible place in your walls, cabinets, or woodwork. Many of the bugs won't survive the winter and will simply die off during the cold season. Long story short, whether they're in the home or not, they won't be very active.
When the weather warms up around March and April, invading pests begin to emerge from hibernation. At this point, they're more active as they look for food and a safe place to breed. You may see limited activity from pests during this time, but not necessarily enough to warn you of their coming infestation.
The colony is most populous during the summer months when the pests have had ample access to food and water and several weeks to nest, breed, and multiply. This is when you'll see the most pest activity.
The best time of year to spray the house for bugs
The best way to prevent an infestation from occurring in the first place is to hire an exterminator to spray chemical pesticides around the house to deter bugs from entering and exterminate the ones that are already there. This is most effective during the early spring months when the weather is warm enough for the bugs to start emerging but before they've found a spot to nest. When bugs first emerge from their dormant period, they are weak and in search of food, so they are not yet breeding, so this is the perfect time to stop them in their tracks.
Treating outdoors for garden pests
Your lawn and garden also see their fair share of pest problems, with some bugs causing damage to your grass and vegetable plant. Destructive garden pests, like aphids, tend to hatch a couple of weeks prior to others, so they have a good amount of time to breed, hatch, and infest without any threat from predators. Spray your outdoor space with plant-safe pesticides in these early spring months once the outdoor temperature is consistently between 50 and 60 degrees F.

Do these 7 things to keep bugs away from your next party

Depending on the size of your bash, you may spend weeks or months planning an awesome outdoor party. The food may be sumptuous, the music perfect, and the decor gorgeous, but the guests will be miserable if they are harassed by bugs the whole time. Protecting your guests from flying pests is a consideration that you should handle well in advance of the party. 

Summer pest control starts with the condition of the landscape itself. The most common summer bugs, mosquitoes and ticks, have very specific habitat requirements that you can either reduce or eliminate altogether. With these few subtle bug control elements, you can ensure your guests will enjoy a great time without suffering itchy welts and blood loss.
Let plants do the work
Plants with fragrant foliage can help chase bugs away. Marigolds, catnip, basil, lavender, scented geranium, and lemongrass, to name a few, harbor a variety of insect-repelling volatile compounds that they release when the foliage is disturbed. Plant them in the yard, add potted plants to the patio, or fill your flower arrangements with them. The more of these plants in the area, the more effective they will be. Pro tip: Just before guests arrive, crush some of the foliage and scatter it in key locations to boost the fragrance and clear the bugs.
Tidy up the landscape
Tall grass, overgrown shrubs, and moist shady areas all harbor breeding mosquitoes and other bugs. Don’t wait until the day of the party to mow, as displaced bugs will simply fly around searching for a new place to hang out. A few days before the event, give the landscape a good trim to reduce insect breeding habitat, improve sunlight penetration, and boost air circulation, all of which deter pests.
Eliminate standing water
Any standing water can quickly become a mosquito breeding habitat. Run sprinkler systems on the lawn or garden only in the morning so that the excess can evaporate in the daytime when mosquitoes are most likely to stay away. Treat landscape water features, rain barrels, and other intentional water sources with Mosquito Dunks or Mosquito Bits that kill mosquito larvae but have no effect on people or pets.
