Keeping pests away
by Barbara Ballinger and Margaret Crane
No one wants an unwanted pest – as in insects or vermin –inside their home, outside on their decks or in their yards.
Not only is it unhealthy, these pests can wreak havoc, cause stress and require pest control experts to remove them. And in worst cases, homeowners may need to hire contractors to repair damage.
Case in point: termites or carpenter ants chewing wood elements are particularly dangerous when they’re eating away at structural members of your home.
What are the best ways to keep your home free of common pests? We asked Dr. Sydney Crawley, an entomologist with Ortho for advice. Here’s what she shared about smart ways to prep your home to avoid the most common unwelcome visitors:
- Caulking can go a long way to shoo them away. Seal tiny cracks and holes near your doors and windows and along baseboards. Use a strong tape that you can find at most hardware stores.
- Store food in air-tight containers (or keep in the refrigerator), especially grains and sweets, and clean up after you cook so there are no crumbs around to tempt them.
- Reduce clutter since it can provide shelter for insects. Clean kitchen and bathtub drains, which can be another breeding place.
- Keep your yard free of debris so pests won’t find shelter in your firewood stacks, compost piles and yard waste. Never stack firewood against your home for the same reason.
- Know that there are stringent laws that dictate that insecticidal products be registered. Guidelines allow the government to evaluate a pesticide’s chemical toxicity to humans, pets and other organisms, as well as the pesticide’s environmental risks.
- Homeowners need to follow instructions on product labels, too. For instance, a pesticide registered for agricultural use would not be appropriate to use indoors. And those who seek a pesticide that does not remain in the environment for very long should consider a product containing essential oils. Also, the appropriate dose should always be used.
Here are more specifics about certain types of pests to guide you. Another good way to be prepared is to have several products from a company such as Ortho on hand to deal with your most common and recurring problems in advance.
Not only are they incredibly annoying as they buzz about — and bite — but they can transmit serious pathogens that cause diseases like Zika and West Nile viruses. Eliminate all sources of standing or stagnant water. Empty and replace water in planters, birdbaths and pet dishes. Keep other water-prone areas like gutters clear. Finally, set up a perimeter around your home that you’ll spray to keep insects away during spring and summer months.
These pests are very hard to eliminate from the home and treatment typically requires a multi-pronged approach including mechanical and chemical control, as well as preventative measures that help avoid a reinfestation. When travelling, make sure to check your luggage and clothes, as they’re known to hitch a ride with you back home. Never put a suitcase on the bed in a hotel, just in case.
To prevent cockroaches, store food in tightly-sealed containers, seal cracks in your home and replace torn window screens. Treat your home’s perimeter with a spray; many will last up to 12 months. Baits are another effective strategy because cockroaches are nocturnal (often feeding at night) and may be difficult to contact during the day. The benefit of using bait is that the roaches do all the work, spreading the bait to kill other roaches in hiding.
Seal up any cracks and broken screens to prevent stink bug entry into your home. Change exterior lighting to less-attractive yellow bulbs, since stink bugs are attracted to light. If you see one in your home, do not touch or squish it, because that will release their foul smell! Instead, gently coax the bug into a plastic bag to release it outside. Since stink bugs move slowly. You may also kill them by using ant and roach killer.
Keep the area under and around your house free from wood debris, above and below ground. Stack firewood away from the house and off the ground. Damp soil also puts your home at risk, as termites prefer moist soil. If you find termites in your yard, use a termite killer. If they manage to infest your home, call a professional to assess the damage, identify the termite species responsible, and eliminate the colony.
Not only can they cause structural damage to your home, they can also be a nuisance and crawl inside in search of food. Ants tend to follow trails along the perimeter of the home, baseboards, the edges of countertops and can use wires and pipes as a highway system within walls. Follow their trails to find and treat the nest. Like cockroaches, baits are also an effective strategy for killing ants.
Know what ticks look like? They’re usually oval and reddish or dark brown and range in size from one-half to two millimetres before feeding. Ticks parasitize a variety of hosts including mammals, birds, reptiles and amphibians. They feed by sinking their mouthparts (hypostome) into the flesh of their host and if left undisturbed, they may continue to slowly suck blood for weeks. Amazingly, they can also survive without feeding for several months. Ticks can carry vector pathogens and bacterium that causes Lyme disease – a very serious ailment causing joint stiffness, neurological problems, or both. In many cases, tick bites and the rash that accompanies them go unnoticed.
To prevent ticks from coming inside your house, form a barrier using an indoor/perimeter insect killer. Inspect yourself and your clothing time you’ve been outdoors. If you find a tick, remove it by pulling upward with pointed tweezers after clasping as close to the skin’s surface as possible. After removal, disinfect the area with rubbing alcohol.
Your pets should be inspected and treated for ticks, too. Inspect their ears or neck, the most common places ticks will bite and where rashes can break out.
Flies are also a major carrier of more than 100 disease-causing pathogens, collecting them on their legs and mouth when feeding. Sanitation is the best way to prevent flies. Eliminate breeding sites and sources of food, and make sure your trashcan has a tight-fitting lid and is cleaned regularly. Keep screens on your home’s windows and doors, and repair if damaged. If you see them near your home, you can kill them on contact with various products.
Ask a pest control expert for help when in doubt or when problems persist.
