To control pests, like everything else, the best form of control is prevention. Preventive pest control provides a solid base for your entire pest control system, and, if carried out properly, will provide almost all the pest control you will need.

What to check 0utside your home

Frequency: Monthly

1. Check the outside areas of your property for weeds and brush.

2. Check for trash, rubble, and debris. These provide cover and food for insects and rodents. Remove anything found.

3. Check all containers like bird baths, pet food or pet watering bowls for stagnant water, and left over food. If you are feeding more than your pet needs, you are inviting predators to dine on your lawn. If you leave standing water, you are inviting mosquitoes to breed.

4. Check for puddles, and standing water. If you find any, be certain to make and execute plans to provide permanent drainage.

5. Check the effectiveness of your mowing program. Look for the presence of thatch. If the grass is getting a little too high between mowings,  you may need to add an extra mowing day. High grass and thatch allow insects and rodents to move undetected in your lawn, and allows weeds time to mature and replant themselves.

6. Check for tree limbs, shrubs, vines, and landscape plants touching your home. Trim them back if they are. They provide a roadway for insects to get onto, and into your house.

7. Check for holes, cracks, and poorly sealed plumbing, electrical, and communication line openings, and seal any you find with caulk or other appropriate materials.

8. Check doors and windows to be sure that screens fit tightly, that the caulking  joints are in good order, and that weatherstripping and sweeps are are not letting light, and pests through.

9. After these steps have been taken, any outdoor pests remaining can be treated with the appropriate insecticides and herbicides. There should be few if any, if the above steps were taken correctly.

What to check inside your home

1.  Check all entries corresponding to those outside, such as cable, plumbing, and electrical entry, and door and window frames. Make any repairs needed.

2. Make sure that the inside of your home is clean, free of  clutter, and free of food crumbs.

3. Look for signs of insects and rodent entry and activity such as feces, and gnawing marks. Use traps for rodents before using rodenticides if at all possible. Use insecticides sparingly if needed, and then only according to label directions.

Home pest control by attrition

Most people approach pest control as though at some point, if we kill enough of them, they will eventually go back where they came from.

There are a few problems with this theory:

• Bugs and weeds do not think, they only react, and their reaction will always be the same as long as nothing changes in their environment.
• The bugs and weeds are already where they came from. When we build a home, we are the interlopers in their territory, and we have displaced them. They will always try to get it back.

Pest control by attrition is a life long commitment to the war against “bugdom”. It is a series of battles that will go on forever, unless something is done to modify the environment. We are occupying territory that they once dominated, and they are always trying to reclaim it!

Home pest control by prevention

In order to make any progress in keeping our property free from these pest insurgents, we have to make our property less inviting, and less accessible to pests. In other words, we must modify our environment to favor us and not the pests. We must make it difficult for pests to gain entrance, and difficult for them to survive. We must create an environment that:

• Denies them what they need to survive.
• Exposes them to natural predation.
• Seals them out.

That is pest prevention in a nutshell.

The practice of home pest prevention

There is a logical sequence that should be followed for controlling home pests by preventing them. The practice involves removing the things that insects and rodents need to survive from the outskirts of your homes environment.

1. Start by clearing away any brush, weeds, rubbish, or rubble from your property. That is what insects use for cover, and for food. If you remove the cover, they will fall back to the next available cover, which will probably be your neighbors yard, so, you might want to share this with your neighbors. Now move toward your home. Remove the things that provide cover throughout your lawn, and mow your lawn more often. I know it is a pain, but it really helps. If the grass is high, insects and rodents use it to provide cover for getting closer to your home.
2. As you move closer to your home, look at your trees. If they are hanging over your roof, or touching your roof, they are providing a way for pests to get to the top of your house, so, trim them back. Don’t just cut the ends off, but trim them back to a lateral branch. If you do this improperly, you could cause an increase in pests, and disease in your trees. Keep your own safety in mind, use ladders cautiously, and pay special attention to power lines.
3. Your landscape beds next to your home are an important area for your pest control efforts. The typical landscape bed is a hotbed for pest activity. Keep vines away from the walls, they provide a road for insects. The same is true for the shrubs in the bed, they should be cut back a foot or more from the wall. Landscape mulch should be kept at least a foot from the homes exterior. This is not standard landscape practice, but it needs to be done.
4. Regulate your irrigation carefully. Too much water invites all sorts of critters into your place. Too little can weaken the lawn, and invite weeds to live in the place of the lawn grasses and landscape plants.
5. Now, to the exterior of your home. Seal everything! cracks, openings around doors and windows, replace worn weatherstripping, caulk around frames, caulk around all pipes, wires, cables, inlets, and anywhere else a bug might get through. Make sure all eve and soffit vents are screened. The same goes for your dryer vent.
6. Do the same inside, with all the corresponding areas. Almost every hole in the outside will have a corresponding hole in an inside wall, and they should all be sealed.

Consider a lawn and landscape makeover

While going through this process, you should also consider major modification to your entire lawn and landscape. Don’t let the word major bother you, this is one area where a little change can be done over a long period of time, and have a major impact, without huge expense. In fact, this could save you money in the long run.

Encouraging natural predation can help lower insect populations. This can be done by adding native trees and shrubs, where lawn once existed, and replacing non natives with native plants in the existing landscape. The native plants will be less susceptible to pests, and the native birds will have more of a reason to hang around and eat the remaining bugs. See: Lawn And Garden: Less Lawn More Garden for more information.

Prevention is always the best means of control, and with mosquitoes, prevention offers the only control that is remotely successful for home mosquito control.

Pesticides offer only limited control for a limited time, mosquito misters are falling under increasing scrutiny, repellents are only moderately successful, and are often dangerous for the user, mosquito magnets and other types of mosquito traps are limited to the ones that are already hatched, and do nothing to stop the larvae, nets and screens are also limited in scope.

There is nothing wrong with any of these methods, they are all helpful in their own way, but they all fall short because they do not deal with the problem at it’s root. To ultimately win the battle against mosquitoes, and the diseases they transmit, attrition will not work. They can always reproduce faster than we can kill them! To win, we need to keep them from becoming a problem to begin with.

Home mosquito control through prevention

Mosquitoes, like any other type of pest, prefer certain habitats. In the case of the mosquito, they need:

• Water for larvae to hatch and grow.
• Cover to avoid predation.
• Blood for reproduction.

Eliminating any of these, will stop reproduction in your area.

Water:

If you have puddles of standing water, buckets, tubs, or any other receptacle for water on your property, mosquitoes can find it, and use it against you. If receptacles are the problems, dump them, and make sure that they can no longer hold water. If the problem is standing water in low spots or puddles, provide a way to drain the water either through surface drainage, that is, fill the low spots and holes, or sub surface drainage, such as a french drain, or a pipe drain with a catch box. If you use the catch box and pipe drain, make sure that the grade on the system is consistent, so that water doesn’t accumulate in the pipe. This could cause mosquitoes to use it as a basin, and become a home for other pests.

Don’t just look at the ground, there are other areas which might hold enough water to encourage mosquito populations such as home gutter systems, which should of course, be cleaned and maintained frequently.

If the water problem is a pond or lake on your property, the problem is not only water, but also cover. In fact, it probably has less to do with water, than with cover.

Cover:

If ponds or lakes exist on your property, you obviously do not want to drain them to get rid of mosquitoes, but you can reduce the amount of cover available. High weeds, and shallow water around the shallow edges of a pond should be removed. If filamentous algae, or pond scum as it is commonly called cover a large part of the body of water, the mosquitoes have a perfect habitat. They have water easily available for producing young, they have blood available from the animals that come to the water to drink, and they have cover in the water for protection from the fish who would otherwise dine on them! Skimming off the algae, or otherwise eliminating it will remove the cover, and and allow the fish to do their job.

If mosquitoes are exposed to natural predators, the predators work very well as a biological mosquito control method. If the predators can’t get to them, they can’t eat them. If you have brush and weeds around your home, it gives mosquitoes a place to hide from the things that like to eat them. It also gives them a place to find small animals for the blood needed for reproduction. If you eliminate hiding places like brush, weeds and high grass, you will drastically lower the population by exposing them to predation by their natural enemies.

Blood:

The female needs a blood meal to produce offspring. That may often come from you! Sometimes it comes from small animals. Reducing the availability of water and cover, reduces the numbers of small animals present to feed the hungry female.

Off site mosquito problems

If you paid attention to the mosquito prevention information above, and followed the suggestions, most of your problem with mosquitoes is gone. There are however, other circumstances that can allow mosquitoes to be a problem for you and your family, and some of them may not be within your means to control. This could include such problems as swampy areas on adjacent properties, or ponds and lakes that exist nearby, and are not properly maintained.  Even if this is your situation, you should still use the home mosquito control methods mentioned above, which will still eliminate most of the problem, and then concentrate on the things you can do about your off site problem.

Neighbors and Officials

Talk with the people who own the adjacent property about the problem. Do this before contacting public health officials. See if there is something that can be done by the owner before involving officialdom. If not, that is your next step. Encourage them to practice long term control rather than short term controls like pesticides. It will cost them less in the long run. If they are reluctant or obstinate, explain the health and public safety issues involved.

Prevention is the most natural of home mosquito control methods because it denies them what they need to thrive and reproduce, and exposes them to natural predators like birds, bats, and fish. These natural predators are the next step in our mosquito control system, biological control.

Biological mosquito control

Biological mosquito control is the next best step in home mosquito control, after we have used the best prevention methods. You have modified the habitat to work against the mosquitoes, now, you should modify the habitat to work in favor of their predators. This can be done by providing shelter and other encouragements for such predators as birds and bats. This can mean providing food sources like natural, native plants that birds enjoy, and a source of clean water like a fountain, or a well maintained, non stagnant bird bath. Bats require the same things. Bird and bat houses differ, but are fairly easily attained.

Other home mosquito control measures

In small areas where water cna not be drained immediately, a light spray of mineral oil over the surface of the water will prevent mosquito reproduction.

There are botanical products available which are effective in killing the mosquitoes that find their way to you. These, used in conjunction with a sound prevention program, work well as a backup.

Mosquito misting systems with plant oils offer a usable tool when used with prevention.

Prevention is where pest control should start, management is what we do for the ones that get by our prevention measures.

The first step in pest management is to be sure that the pest prevention measures we have taken are adequate and appropriate. If there are problems with this, they should be solved before any chemicals are used.

Pest management other than pest prevention

The progression should be from least hazardous to most hazardous, of course starting with:

• Pest Prevention.
• Soaps. It is possible to kill most insects with insecticidal soap, even dish soap and water will work in limited circumstances.
• Some botanical products consisting of various plant oils also work well, but may have a slightly overwhelming fragrance when used in tight quarters.
• Traps can be very effective when used properly, and are available for insects and rodents.
• Commercial chemicals.

Pest control, other than pest prevention should always be approached cautiously, and with safety in mind. It should be remembered that when it comes to pesticides, the label is the law. Pay special heed to the warning found on each and every EPA registered pesticide label:

“It is a violation of federal law to use this product in a manner inconsistent with it’s labeling.”

Keep in mind that the label instructions are not written solely for safety, but also for effectiveness. There are many cases where using more than the proper amount of a pesticide will result in lower product effectiveness. An example of this is the improper use of  glyphosate, the active ingredient in “Roundup”. If too much is used, it will result in the dessication of the top of the plant, without allowing time for the chemical to reach and kill the root.

Pest control should be an integral part of any home maintenance program. Pest control should also be a part of an integrated home maintenance program.

No matter how well your indoor pest control is handled, the insects and other pests on the outside will always try to find a way inside. An integrated home pest control program should include steps to keep the outdoor pests, outdoors. Doing everything possible to prevent pests is the first and best form of controlling pests.

Key points to preventing pests:

• Make sure that the outermost parts of your property are cleared of debris, weeds and brush.
• Mow your lawn in a timely fashion, and at a proper height.
• Trees should be properly pruned to keep them from touching, and if possible, from overhanging the home. This is a good point to remember when building a home, or planting trees.
• Landscape plants and mulch should be kept at least 1 foot away from the home. This is a good point to remember when building a home or installing landscapes.
• Irrigation should be monitored to prevent over irrigating and puddling.
• All low spots, and any receptacles should be drained. See Home Mosquito Control And Prevention for more on this.
• Seal all potential insect and rodent routes of entry into the home. Look for cracks , missing mortar and caulk, and small openings around cables and plumbing.
