[00:00:00.711]This is Amy Timmerman with this week’s Extension update.
[00:00:04.202]September is here and thus fall is here!
[00:00:06.882]Most pests reach their maximum population levels around August or September,
[00:00:11.602]and their favorite places to escape the heat of the summer sun
[00:00:14.952]or the oncoming winter cold are our homes.
[00:00:18.342]Keeping fall pests out can be a challenge, but being prepared and properly treating
[00:00:22.858]infestations can make fall a much more pleasant time for homeowners.
[00:00:26.858]The first type of invaders come in on the ground and include crickets, cockroaches,
[00:00:31.374]centipedes, millipedes, ground beetles, spiders and ants.
[00:00:35.889]These pests are attracted to the leaf litter and debris found around the
[00:00:39.889]foundation of houses, as well as the shade offered by surrounding landscape vegetation.
[00:00:45.429]From the foundation, these ground invaders will then
[00:00:48.399]wiggle their way into homes through any crack or crevice they can find.
[00:00:52.399]The second type of fall invaders enter homes from the air and include:
[00:00:56.523]multi-colored Asian lady beetles, house flies, cluster flies, yellow jackets, fruit flies,
[00:01:02.387]boxelder bugs, miller moths and mosquitoes.
[00:01:05.587]Many of these pests are also highly attracted to outdoor lights, such as
[00:01:09.157]porch lights, and enter homes when nearby doors are open.
[00:01:12.937]The exception is Fruit flies, that may enter homes as eggs already laid
[00:01:16.937]in fresh produce, or they are attracted to fruits and vegetables sitting inside.
[00:01:21.594]Fruit flies are small enough and can fit through window screens.
[00:01:26.643]Thus it is important to keep all produce in secure containers inside refrigerators
[00:01:30.943]and dumping compost buckets daily will help prevent homes from becoming
[00:01:34.643]attractive destinations for fruit flies.
[00:01:38.055]The good news is most of these invaders are simply seasonal nuisances.
[00:01:42.895]They pose little threat to human health or damage to the home.
[00:01:46.895]There are several things you can do to prevent these pests from invading your home.
[00:01:51.093]1. Secure points of entry, especially under exterior doors and windows.
[00:01:56.503]Caulk and seal around utility entrances, cracks in the foundation
[00:02:00.503]and gaps around fascia boards.
[00:02:02.710]Install screens over pipes and closeable chimney caps.
[00:02:06.283]Install weather stripping under and around doors and windows.
[00:02:09.903]Repair or replace damaged screens.
[00:02:12.372]Replace rubber seals along bottom of garage doors.
[00:02:15.252]Keep doors closed when not in use.
[00:02:18.082]2. Change lighting around the exterior to reduce attractiveness to pests.
[00:02:23.529]Switch bright incandescent bulbs for yellow ones.
[00:02:26.629]Turn lights off at night, otherwise put on a timer or install a motion sensor.
[00:02:32.254]3. Keep exterior of structure free of debris, leaf litter, piles of organic
[00:02:36.644]matter, firewood, excessive vegetation and clutter to minimize outdoor hiding places.
[00:02:43.664]4. Reduce moisture around buildings by practicing sanitation techniques.
[00:02:49.060]Fix leaks, remove debris from gutters, adjust rainwater runoff, change the
[00:02:53.780]grade, minimize condensation, increase ventilation in crawlspaces or basements,
[00:03:00.700]minimize dark damp corners and eliminate possible indoor retreats.
[00:03:04.976]And finally. Insecticide application in the form of an outdoor perimeter
[00:03:09.254]treatment may be warranted for major infestations of accidental invaders.
[00:03:13.826]Foundation sprays to keep ground invaders out should be sprayed
[00:03:17.776]3 to 4 feet up the house walls and 3 to 5 feet out from the house.
[00:03:23.356]Make sure to read the directions and follow the labels.
[00:03:27.482]There are some commercial baits formulated for crickets.
[00:03:30.922]In the case of overwintering pests, such as boxelder bugs and cluster flies,
[00:03:34.922]a residual treatment to the exterior may be performed by a professional pest
[00:03:39.302]management company to keep them from entering in the fall, but timing is the key.
[00:03:44.084]If you know you have overwintering populations in wall voids or an attic,
[00:03:48.658]do not attempt to treat and kill them while they are hibernating.
[00:03:52.588]Dead bodies will attract secondary pests such as carpet beetles.
[00:03:56.748]If you do find yourself with one too many uninvited house guests in your home,
[00:04:01.921]the simplest way to rid yourself of them is to vacuum them up any that you see,
[00:04:06.701]discard the vacuum bag contents and follow any preventative steps that we went through.
[00:04:12.584]For more serious problems, indoor-use aerosol sprays are available.
[00:04:18.387]If the infestation is severe, it is always best to hire a professional pest control operator.
[00:04:23.819]However, there is no need to call pest control at the sight of a single cricket or centipede.
[00:04:31.740]Any questions regarding the creepy crawlies in your home
[00:04:34.800]please contact the extension office and we will help in identification.
